network throughput

Does this sound like a problem with ESXi and, if so, any ideas on how to fix it?

It seems that I'm the slow file transfer rate to my VMs ESXi - 13 MB/s on average.  I'm trying to figure out how to get the best transfer rates.

My configuration:

File server with Ubuntu, 6 GB ram, 2.4 ghz double heart, an Areca Raid Controller (1230 w/1 GB of cache) and 8 Seagate 2 TB drives configured as a single Raid 5 volume and two ports bonded ethernet (802.3ab).

The Dell PowerConnect 2724 switch - gigabit 24 ports with 802.3ab support.

ESXi server with an i7 920, 12 GB of ddr3 (1600) and 3 Western Digital drives black 1 TB (10 k RPM), Intel Pro/1000 PT Dual Port Server Adapter.

My tests:

Base - how quickly a 700 MB file will transfer to the source file to the destination server.  I know... IOmeter, etc. is best for measuring performance, but please bear with me, since I have not installed IOmeter and I don't know how to use it yet.

Test 1 - destination is a desktop computer connected to the switch Gigabit, duplex full.  Transfers of files in 10 seconds.  The Office has a network utility that reports an average 65 MB/s transfer rate

Test 2 - destination is a virtual computer running on the desktop (VMware Fusion).  Transfers of files in 15 seconds.

test 3 - destination is a virtual computer running on the ESXi server.  Transfers of files in 55 seconds.

Test 4 - copy (and not move) the file from one folder to another within the VM ESXi.  File copy in 10 seconds.

Additional notes:

-ESXi a vmnet0, the two ethernet ports are added, joining a hash based on intellectual property

-On the file server CPU usage never exceeds 10% on any of the tests

-J' ran all the tests with Windows 98 and Linux (Ubuntu) virtual machines

-All the virtual machines have installed the VMware client

Conclusions:

It seems that ESXi is misconfigured somehow, because a file 13 MB/s transfer rate seems slow because the file server can feed the same file different destination 5 times faster.  I try to get ESXi use 802.3ab collage for a higher rate, but it seems that I should get more than 13 MB/s even with a port single gigabit.

What can I achieve the network greater throughput / faster?  That is to say. Make the file copy faster transfer of the file server to one of the ESXi virtual machines?  I have to configure something differently?  I have to install quad gigabit or 10g?  I have to go with iSCSI?  Or is there a configuration item that just needs to be tweaked for better performance?

Far switches will also, I like the Dell. I think they offer really good features for their prices relatively low. My choice would be to stick to those.

Thanks and take care.

  • 5.1 network throughput problems c7000 and vSphere

    Hello, I'm new to the forum and I want to say hello to everyone!

    Here is the main reason why I joined the forum:

    I have a weird problem with my HP C7000 enclosure and VMware vSphere 5.1

    I used a standard vSwitch to connect virtual machines and associate them with a vmnic for my traffic from public network segment. With this configuration, I found that when I tried the command SCP to copy some files from VM1 VM2 to, there where good productivity, just as planned, but when I tried to copy to VM1 VM2, it just drag at a ridiculous speed, like 16 Kbps up to it just hold. I could repeat the same behavior whenever I try. So I just tried using the vswitch distributed, and the behavior has changed. Now traffic of the CPS goes as it should be between virtual machines, but the problems of flow between a virtual machine and a physical host like this: when I copy from the physical host to virtual machine, flow is as it should be, but when I try to copy the VM on the physical host, yet once it stalls.

    Please can someone give me some clues?

    Here's another thing, I have a blade with vCenter in 2012 Windows installed it works as it should with external hosts.

    I used vSphere in other environments and never had something like this behaviour before.

    Thank you.

    Hello

    I found the problem, the switch was defective. Just changed to an e3800 HP switch and all together.

    Thank you!

  • Average throughput of the network to a virtual machine with PowerCLI

    I would get average network throughput for a virtual machine with PowerCLI including all e-cards, the virtual machine has for the last week (not including NFS or storage of traffic-related).

  • 5.0.15 server performance (El Capitan) poor SMB3

    I have a clean of El Capitan and Server 5 installation and recently spent all my clients to connect via SMB on the server instead of the AFP, but many users have reported to me very slow performance Finder, on a range of computers (MacBook Air, iMac, Mac Pro) so I can pin only which is a problem with the server itself.

    I read about the process of "sdmd' on the server by using unnecessary CPU, caused by actions that have iOS active sharing. I disabled this for all my actions, in the hope that maybe that was the reason for the client slow Finder performance, but that wasn't the case.

    I'm sure to SMB3, despite all the 'hype' and 'what's new' and 'faster' performance before it is sold.

    I checked the SMB connection on the clients that it is indeed SMB3 and not SMB2.1 (all clients are El Capitan).

    Anyone has any ideas, or to the settings that I can perform?

    With the help of Blackmagic Disk Speed Test I can get about 120 MB/s, so network throughput is not a problem.

    Return to AFP back a normal performance (fast), but with Apple seeking to interrupt the AFP in the future, I would really have confidence in SMB3... !

    Hi Robert, I've experienced a similar problem, but vice versa, AFP hangs for a long time while SMB is fairly elastic.  Same configuration, last El Cap with Server 5.  Very strange.

    My problem is with SMB I don't then open, and then save the files to the server, I get the message that I don't have permission (even if I use the same password on the server, and the volume and the files have the same administrator permissions).  If I go to the AFP, it works fine.  But this brings us to another problem where my volumes will not be displayed on my client computer with AFP only enabled, the only way to see these volumes is by clicking 'Connect to server' in the menu go to.

    It's a riddle here, I want the whole cake, but I am only able to get a slice at a time.  It makes me crazy!  I am very interested to see what people add to this thread...

  • JOINT inspection on 100% load

    Now I have JOINT with 100% load on the rush hour and followed by missed packets percentage increasing at this time where inspection.

    It's my network throughput will be limited by the load max JOINT inspection / flow which is 600Mbps?

    Thank you

    Marcel.

    No, the flow wil not be limited in the network when you are in promiscous mode. But your visibility for attacks is very limited.

    You must configure your settings of term/capture on the 6 k 5 only send so much traffic that this module can handle the method.

    Please keep in mind that the JOINT-2 is a system of ten years and cannot catch up with the typical traffic demand, we are having today. It's time to change the JOINT against a real external sensor.

  • Effects of the performance of 802. 11B clients on customers 802.11 g

    Can someone tell me what effect in what concerns the speed a 802. 11 customer b would have on a customer 802.11 g. Especially on a network using AIR-LAP1242AG-E-K9 access points.

    I've read elsewhere that when you use the older client 11 b AP will be degregate performance for 11g clients. Is this always the case for the AIR-LAP1242AG-E-K9?

    Does anyone have a stat for this?

    Dylan

    Hi Dylan,.

    Yes, customers of 'B' will be stil have a significant effect to take a look at this clip.

    When 802. 11B clients are * associated with an access point 802.11 g, the access point will start a protection mechanism call Request to Send/Clear to send (RTS/CTS). Originally a mechanism to address the "hidden node problem" (a condition where two clients can maintain a connection to an access point, but due to the distance can not hear the other), RTS/CTS adds a degree of determinism to the other network to multiple access. When RTS/CTS is invoked, the clients must first request access in the middle of the access point with an RTS message. Until the access point replies to the client with a message from the CTS, the client will refrain from access to the average and transmitting its data packets. When received by customers requiring abstain to access the average, other that the one who sent the original RTS, CTS control is interpreted as a command "do not send". You can see that this mechanism will prevent 802. 11 customers to transmit simultaneously with a 802.11 client b g, which avoids collisions this drop in flow due to attempts. You can see that this additional RTS/CTS process adds a significant amount of protocol overhead, which also translates into a reduction in network throughput.

    In addition to the RTS/CTS, the 802.11 g standard adds another important condition to enable 802. 11B compatibility. Where a collision occurs due to simultaneous transmissions (the probability that is greatly reduced due to the RTS/CTS), client devices 'reverse' the network for a random period before attempting to access the average again.

    Note that the increase in throughput for 802.11 g running in mixed mode is relatively modest compared with the 802. "11b and is a fraction of the flow provided by 802.11 g, when he supported not customers not inherited.

    It is well described in this great doc;

  • vSphere 5.5 with ethernet Intel x 540 - AT2 10BG question

    VMware ESXi 5.5 with 10GB network card upgrade and switch hosts cannot do more than transfer of 750MBIT

    vSphere 5.5 with ethernet question intel x 540 10BG

    https://communities.Intel.com/thread/48512?start=0 & tstart = 0

    We have dealt with this problem as these cards have been installed. We only run a custom lenovo ISO of ESXi 5.5 U3 on our 4 hosts. We have a complete infrastructure of 10 GB (switch/router/host). We do not seem to make more than 300 MB/s speed between Windows clients with network throughput tests, such as iperf and psping.

    Between two VM linux on the same vSwitch, we can get a full 10GB and a little less during the delivery. We have not activated jumbo frames. We have tests with frames and get better speeds, but I don't think it should be necessary since we can get the full flow under Linux. I have a box to open with VMWare and no real progress has been made, they suggested tuning some settings on the network adapters in windows nothing helped.

    Before I linked to similar problems with Intel 10 GB cards, other persons must have met as well.

    I ended up resolving this issue. It turns out that RSS wasn't working properly in our test VMs so she distributed no treatment on the other cores of vCPU. It was indexing a processor and the others were at 0%. After the active spin up to two virtual machines on 2012 with RSS, I could easily break our previous limits. Another adjustment is possible, but we were getting ~8.5Gb/s with only the active RSS.

  • Maximum traffic for a vmxnet3

    Assuming that there are no bottlenecks elsewhere, what is maximum penetration network traffic that a unique vmxnet3 adapter on a virtual machine can receive network?  It is 10 Gbit/s (gigabytes per second) or 10 Gbps (GigaBITS per second)

    Thank you!

    In theory and in the physical world, the maximum data rate would be 10 Gigabit/s, since vmxnet3 emulates a 10GBASE-T physical link.

    This flow is governed by physical limitations and traffic on the wire of the standard, but these do not apply in a purely virtual configuration (vSwitch and port group 2 virtual on the same host and same computers).

    Invited on the same host and vSwitch and port group are able to exceed beyond 10 Gbit/s. I know, we could think that for example the e1000, which has a link from 1 Gbps to the guest, is limited to 1 GB/s maximum. or vmxnet3 is limited to a maximum of 10 Gbps. But this isn't the case. They can easily exceed their "speed of the virtual link. Test it with a tool of network throughput as iperf a see for yourself.

    This is because only the true physically imposed restrictions do not apply in a virtualized environment between two virtual machines on the same host/port signalling group. Operating systems don't artificially restrict traffic to match the speed of the agreed line unless it is physically required.

    To give you an example, I am able to reach 25 + Gbps between 2 virtual Linux machines with a single on the same host/network vmxnet3 vNIC

    For reference, I am able to get 25 + Gbps with the test tool of network throughput iperf between two virtual Linux machines with a vNIC vmxnet3 unique on the same host/port group. (Yes, 25Gbps. Even if a vmxnet3 emule link 10 Gbps, throughput is not artificially capped without physical limitation of signal).

    Once you get to the external communication outside a host then you are limited by your physical host of ESXi links limitations.

  • vmxnet3 driver performance

    I'm looking to increase performance on our environment.

    I plan the update to the hardware versions 7 to 9 of the guests for our database servers and know that this includes support for vmxnet3 driver with 10GB network connections.

    My question is, if the underlying hardware switch has only 1 GB of the physical switch ports. If the guests are on the same host they will communicate within the hypervisor at speeds of 10 GB or that it will always be limited to 1 GB.

    Any help would be appreciated.

    Thanks in advance

    Karl

    I plan the update to the hardware versions 7 to 9 of the guests for our database servers and know that this includes support for vmxnet3 driver with 10GB network connections.

    vmxnet3 is already supported since VM hardware version 7.

    My question is, if the underlying hardware switch has only 1 GB of the physical switch ports. If the guests are on the same host they will communicate within the hypervisor at speeds of 10 GB or that it will always be limited to 1 GB.

    Invited on the same host and vSwitch and port group are able to exceed any vNIC well beyond 1 Gbit/s you use. I know, we could think that for example the e1000, which has a link from 1 Gbps to the guest, is limited to 1 GB/s maximum. or vmxnet3 is limited to a maximum of 10 Gbps. But this isn't the case.

    To give an example, I am able to reach 25 + Gbps between 2 Linux VM with vmxnet3 on the same host/network with iperf.

    The main advantage of the vmxnet3 vNIC is that it provides features of unloading and paravirtualization, which reduces the CPU load imposed by their high throughput. I'm under it years since 4.x on Windows and most Linux virtual machines as our standard vNIC.

  • Can not know why my VM download high speed but horrible upload speed... help?

    HI -.

    I hooked 5.1 on a gigabit network and just do a few network tests. I tested a Win 2 k 12 virtual machine using LAN Speed Test and got up to 475 Mbps down but only 38Mbps verifying against a NAS part I. By way of comparison, I checked a physical machine against the NAS share and saw 350-400 on both sides. I'm naïve about why the download speed would be so slow when downloading indicates clearly that I have gigabit speeds. Has anyone ever encountered this before?

  • Best way to access the 2 TB volumes +.

    Please tell me if you think this is the best approach.  I'm new on ESXi and I'm still learning how to take advantage of it...

    I have a server with 8 x 2 TB Seagate drives, a material in Areca 1230 raid controller and an additional Seagate hard disk of 500GB.

    I want to get the highest throughput and the best performance since records of 8 x 2 TB and the Areca raid controller, support RAID 5 and the ability to use disk space in ESXi.

    The system is currently configured as follows:

    -ESXi is installed on the hard disk of 500 GB; I would like to use a USB flash drive,

    but the motherboard does not support boot from a USB flash drive.

    -8 x 2 TB drives are assigned to a RAID, and within the entire raid, raid volumes 5-8 x 2 TB have been created.

    -Inside the ESXi, the first raid volume created a store of data and then I added the remaining volumes as extensions.

    -Gigabit ethernet (full duplex) - no jumbo frames

    -6 GB of RAM of the system with a processor core 2 duo

    Amount of space between the new data store has been assigned to one of the machines virtual and all tested well.  For example, I was able to copy a 2.4 GB file from one directory to another in 24 seconds.  This looks pretty good to me, since the specifications of disks show that they can maintain 95 MB/s of throughput.  I am trying to find how to install / use IOMeter to get more accurate test results.

    I created a SAMBA share and ran two tests.  Copy a file to the server from the network suffered between 50 Mbps and 54 Mbps.   Reading a file from the server also maintained between 50 Mbps and 54 Mbps.  This seems odd for two reasons.

    First, I tested the system with Ubuntu and SAMBA (no ESXi) and the files copied to the server at 66 MB/s.  Would imply it that ESXi General encurs that slows down the performance of the network by about 12 MB/s to 16 MB/s.  This seems a lot and gives me the impression that I did something wrong.

    Second, with ESXi installed, network throughput was between 50 Mbps and 54 Mbps all the time.  There was no initial explosion of high performance and throughput does not slow down over time.  This seems odd.  Wouldn't buffers / cache come into play?  For example, the Areca raid controller has 1gig of ram.  All least, shouldn't expect higher rates until the cache is full?  I've seen this problem on other NAS drives and I'm a little surprised that I'm not work in here.

    Thanks in advance for any thoughts, comments, or recommendations you have on any aspect of this - I should get this or comment on the raid controller, how it was configured, how better understand space in ESXi, or even advice on what kind of network throughput.

    For once I disagree with (sorry) DSTAVERT - given that all eight extensions are hosted on the same underlying RAID volume, there is no additional risk [/ b] in this configuration compared to a single set of 8 TB RAID-5 can be used without ESX.  If something goes wrong in this scenario, all eight extensions would be affected simultaneously.

    With respect to performance, this seems reasonable to me.  Keep in mind that for virtualization are generally is much more on random IOPS throughput / s sequential read (or write) block.  Eight batteries will help with that but disks SATA quickly bogged down unfortunately.

    You have to have one-Core 2 Duo, I would suggest running with 1 vCPU only guests.

    Please give points for any helpful answer.

  • Network: 2 routers Apple broadcasting separate wireless networks; one (Xfinity/Comcast) cable modem

    Hello community!  Need help, I want to use two routers to establish two separate wireless networks on a cable modem connection.  I searched for my answer and see some other threads on this topic, but all are either a bit too technical for me, are incomplete on the answers to my questions - and all seem to be locked.  I have also searched YouTube and only see videos to extend a network with two routers - not my goal.  So here is a long, but a detailed post on what I need someone help with - thank you very much in advance if anyone can all small-not me-I hope it will be useful to others in the future.

    The program installation/hardware: I have internet Comcast/Xfinity that runs to a Motorola surfboard cable modem (SB6141).  I also have two routers apple - a Time Capsule from Apple AirPort (to end 2013) and a new (2016) AirPort Extreme.

    Purpose: This is what I need--I need two separate wireless networks.  Before going further, by using the guest account and 5 GHz of a single router isn't an option for me.  I need to have both wireless networks separate (one of each router), do not talk to each other, or allow access between the two - the only is that they share the Comcast internet gateway.

    My plan is to have the cable modem Surfboard connect to airport Time Capsule, which will then connect to AirPort Extreme (even if it could be reverse - no difference, except that the data that I show below comes from the time Capsule, which is currently connected to the modem cable).

    To read the previous discussions, it seems that the starting point would be: modem router #1 Ethernet WAN, then a router cable #1 LAN Ethernet to the Router #2.

    First issue of clarification - the connecting cable should go to the Ethernet WAN port on the Router #2 or a LAN Ethernet port?

    Now that the first easy question is the road, I need help to configure two routers connected to allow two separate networks.  A lot of discussions about the positions of static IP addresses, cascade, etc..  I need specific help with AirPort Utility on what to change on what router.  It seems obvious that the settings under the 'Internet' and 'Network' tabs are those who need to set - the 'wireless' tabs simply treats the name of the wireless network and settings - these, at least I can understand!

    I'll organise this tabbed - here go us.

    First of all, the "Internet" tab/window Airport utility. Here are the options:

    Connect using: Router #1 has currently DHCP (which I think is OK?) What should it be set to Router #2?

    This tab lists also the current address in IPv4, the (255.255.254.0) subnet mask and the router address.

    It has grayed out information in the boxes for the DNS servers; Name of domain and DNS IPv6 servers.  At the bottom of the window, there is an IPv6 Internet WAN address listed.

    If I click on the "Internet Options" button at the bottom of the window, it takes me to the 'Internet Options' window. Here, there are various IPv6 information - it seems that I can choose the configuration of IPv6 and the IPv6 mode using the drop down boxes/selections were also chosen.  There is also a checkbox 'Enable IPv6 connection sharing'. Are the current settings for these for Router #1: configure IPv6: automatically; IPv6 mode: Native; and check/yes to enable sharing of IPv6.

    Next up, the 'Network' tab utility AirPort/window.

    Here, there is a drop-down menu "Router Mode", a DHCP range listed, and the ability to add or remove reservations DHCP and Port settings.  The DHCP range listed for Router #1 is 10.0.1.2 to 10.0.1.200.  There is currently no reserves DHCP or specified Port settings.  Finally, there is a checkbox to the bottom to "Activate the access control" - it is not currently checked/enabled.

    If I click on the 'Network Options' button at the bottom of the window, it takes me to the "Networking Options" window Here I have areas of entry to specify the DHCP lease duration, can specify the DHCP IPv4 range, as well as part of the extended DHCP IPv4 comments.  There are checkboxes: enable NAT Port Mapping Protocol. Select the host by default (with input if selected text box); Enable the IGMP Snooping; Block incoming IPv6 connections; Allow the Teredo Tunnels; and allow inbound IPSec authentication.

    For this window, here is the current settings on the Router #1:

    DHCP lease is 1 day; Beach DHCP IPv6 is 10.1.2 to 200; Hosts IPv4 DHCP Range is 172.16.42.2 to 200.  The following check boxes are enabled/checked: enable NAT Port Mapping Protocol. Block incoming IPv6 connections; And allow inbound IPSec authentication.

    Who can help me? What parameters, if all do I need to change the #1 router?  How to set up router #2 to make a second wireless network?

    Purpose: This is what I need--I need two separate wireless networks.  Before going further, by using the guest account and 5 GHz of a single router isn't an option for me.  I need to have both wireless networks separate (one of each router), do not talk to each other, or allow access between the two - the only is that they share the Comcast internet gateway.

    What you really need is a combination router / Ethernet switches that s supports VLANdedicated. Given that Apple routers do not, at best, you can potentially get the results that you are looking for, but at a performance cost. In other words, you can have two separate WiFi networks where clients connected to a network can not 'see' those related to another and both routers will always provide access to the Internet through Comcast modem. Note: Arris / Motorola SB6141 isn't a gateway device. Instead, it's a simple modem. A gateway is a router modem combination.

    To do this, should do the following:

    • The Time Capsule (TC) would need to be directly connected to the modem using an Ethernet cable. This base station would remain in its default configuration of the router. In other words, the router Mode (in AirPort Utility) would establish: DHCP and NAT.
    • AirPort Extreme would be directly linked to TB by Ethernet. The cable must be connected to one of the LAN ports on the TC on the WAN port to the extreme. It must also be configured as a router. However, there are differences in the extreme:
      • Use a different name to the Wi - Fi network.
      • Use another range of IP DHCP address. By default, Apple base stations use IP addresses in the 10.0.x.x range. I suggest that you set the base station of the second on 192.168.x.x range.

    There is a major drawback with this configuration. The second base station will be in a State of "Double NAT". Although this "separating" the two networks on different subnets, this condition is not very effective and connected to this network of customers will get lower throughput performance. There is no way around it and it is not recommended.

    First of all, the "Internet" tab/window Airport utility. Here are the options:

    Connect using: Router #1 has currently DHCP (which I think is OK?) What should it be set to Router #2?

    The two should be: DHCP.

    This tab lists also the current address in IPv4, the (255.255.254.0) subnet mask and the router address.

    These leave it as what. The TC is information of IP address of the modem. The extreme, he'll get the TC.

    It has grayed out information in the boxes for the DNS servers; Name of domain and DNS IPv6 servers.  At the bottom of the window, there is an IPv6 Internet WAN address listed.

    These leave it as what.

    If I click on the "Internet Options" button at the bottom of the window, it takes me to the 'Internet Options' window. Here, there are various IPv6 information - it seems that I can choose the configuration of IPv6 and the IPv6 mode using the drop down boxes/selections were also chosen.  There is also a checkbox 'Enable IPv6 connection sharing'. Are the current settings for these for Router #1: configure IPv6: automatically; IPv6 mode: Native; and check/yes to enable sharing of IPv6.

    Unless your ISP provides your IPv6 service, change the IPv6 configuration option to: 'Link-local only' on two base stations.

    Here, there is a drop-down menu "Router Mode", a DHCP range listed, and the ability to add or remove reservations DHCP and Port settings.  The DHCP range listed for Router #1 is 10.0.1.2 to 10.0.1.200.  There is currently no reserves DHCP or specified Port settings.  Finally, there is a checkbox to the bottom to "Activate the access control" - it is not currently checked/enabled.

    Router mode should be: DHCP and NAT to two base stations. Ignore the DHCP reservations and Port settings for now. Let the current DHCP range for the TC. Change the DHCP range for extreme for: 192.168.1.2 a.200. At this point do not access control for each base station.

    Since you seem to need the step by step instructions or need help to understand the different terms networking, I highly recommend that you help you to become familiar with networking, specifically on Apple systems. I suggest you consider taking the e-Book to the next control: take control of your Wi - Fi Applehttps://www.takecontrolbooks.com/apple-wifi network

  • For pavilion a6030n wireless network adapter

    Can anyone recommend a card for my Pavilion a6030n wireless network?  Maybe a good router too?

    Based on the specifications of your HP Pavilion a6030n desktop, you can use the traditional PCI cards and more recent PCIe wireless. In addition, you can also use an adapter without wire/USB dongle, if you do not want to open your computer.

    I would say get a dual band 802.11 wireless network card b/g/n at least, but you might want a wireless 802.11 adapter ac its better range and throughput. With respect to the router, I suggest to get an ac wireless router.

  • BEFSR81 and static IP to be assigned to the members of the network

    It's perhaps a little noob question.

    I have to (192.168.1.2 DHCP server OFF, wireless) WRT310N cascading through my BEFSR81 (192.168.1.1, DHCP ON), but for the life of me I can't understand where they were hiding a DHCP reservation. If there is no page for it, I was unable to find anything that looks like a workaround solution. I want to put in place so that the members of my network get the same IP addresses addresses DHCP and time "guests".

    Can someone help me?

    Thank you

    An obvious option is that you can replace the BEFSR81 with almost all new Linksys routers.  You can use the RVS4000 (a DHCP reservation has been added with an update of the firmware), or you could use a wireless router and turn off the wireless.  If you're thinking the RVS4000, know that it can handle only about 15 Mbps of throughput of your Internet connection, so if you have a faster connection, you'll be out of luck with this router.

    If you wish to continue using your BEFSR81, note that Linksys has certain rules very specific on how to manually setup fixed LAN IP addresses in your network devices.  You must follow these rules carefully.

    Rules for use of the LAN IP fixed address on the Linksys routers:

    With Linksys, routers, a fixed (static) IP LAN addresses must be assigned in the device that uses the address. If you enter the fixed address to the computer or the printer, not in the router.

    When you use a Linksys router, any fixed LAN IP address must be outside the DHCP server rank (typically 192.168.1.100 thru 192.168.1.149), and may not end with 0, 1 and 255.

    That's why any fixed LAN IP address would normally be of the order of
    192.168.1.2 thru 192.168.1.99 or
    192.168.1.150 thru 192.168.1.254
    assuming that you always use the default DHCP server line.

    In addition, in the computer, when you configure a static LAN IP address, you need to set the "Subnet mask" 255.255.255.0 and the 'default gateway' on 192.168.1.1 and "DNS server" on 192.168.1.1

    It is also important that the same value static LAN IP address no two devices on your network.
