• BEFSR41v2 hub switch

  I read a lot of posts online and think that I have figured this out, but I just want to know that. It seems that I am not not alone trying to do... I have a BEFSR41v2 and have since upgraded to a wireless router. Now, I need a hub and have read that I can disable DHCP in the BEFSR41 and use it as a hub. If I understand correctly what I read, I hang the cable from my current wireless router in the port of uplink on the BEFSR41 and then have correct 4 ports available for expansion without using the WAN port - making that noise? Also - is that what I should have the router (now configured as a hub) defined to obtain the IP address automatically, set a static IP address or what? Finally - the firmware is the original firmware 1.42.7 (April 2, 2002) and I've read where people have problems after the firmware update. Should I update the firmware? Thanks in advance for any help.

  In response to your questions:

  (1) the difference between a hub and a switch, it's when a hub receives a data stream, it broadcasts this stream to all the computers to which it is connected and the correct (receiving) computer realizes that the data are designed for it, so he picks up this flow, while other computers realize that the data stream is not for them While they ignore the flow.  A hub is limited to "a connection" at the same time.  A 10/100 hub would be a maximum bandwidth of 100 Mbps.

  A switch can make multiple connections at the same time, with all the ports running in both directions.  If a switch 8 ports can be up to 4 simultaneous connections to 100 Mbps in each direction, for a total bandwidth of 800 Mbps.  The key is that a switch can handle more traffic at the same time without having your data "bump heads", happening in your network.

  Because a switch costs only a few dollars more than a hub, I usually just buy switches.

  (2) when you use the Uplink port, you cannot also use port 1, because these two ports are directly connected.  The only difference between the Uplink port and port 1 is that two of the sons are reverse connected.   Port 1, 2, 3 and 4 normally communicate with each other through the firmware of the router (or switch), no direct wiring.  So normally the firmware controls the "switch" that is occurring.

  (3) you questions on a 'faster' switch    The data transfer speed is limited by the slowest links in any connection.   Note that a compressed high definition signal (the signal recorded by DVR) TV is probably only 6 Mbps or less.  If your DVR probably only has a port 10/100 on it.    If your DVR has a gigabit port to this topic, then you can consider a gigabit switch, but otherwise stay with a 10/100 switch.  The only time where a gigabit switch is beneficial, it is when two computers (or other devices) that are connected to the it are the sharing of data, and both devices can process data at speeds more than 100 Mbps.

  (4) if the SD208 a lack of ports, you must consider the SD216 (16 ports), or cascading two switches SD208, or a SD208 more the BEFSR41 (converted to a switch).  Yes, you can mount two switches cascaded in a row.

  (5) all your ethernet cables should be standard (straight through) cables.  All routers and the modern switches have ports "auto detection", meaning that they automatically cross the cable necessary for the system to work, so ADJUSTABLE uplink ports, and cables are no longer necessary.  This is why the switches, such as the SD208, do not have an Uplink port.

  (6) the switches I talked of should work with your Netgear router.

• GS728TP: PoE fault

  Hello

  We just purchased a Smart GS728TP PoE Switch.

  Unfortunately, when we plug in a new device requiring of PoE, the switch must be rebooted before will recognize (and power) of the new device. It works without problem once this has been done.

  I raised a support ticket and Netgear advised me, it must be a hardware failure on the device. They suggested that I return to the vendor.

  My initial intention was to buy a GS724TP, but was apparently it is now obsolete and the GS728TP was a direct replacement.

  We also have a GS748TP (purchased at the same time), and it works without any problem of PoE.

  Has anyone encountered a similar problem?

  Maybe I missed something obvious in the configuration. However, I have done a factory reset (and also waited 20 minutes to see if the switch recognizes the device without having to reboot).

  Many thanks in advance,
  Stephen

  Hello

  I am very happy to find a topic referring exactly the issue I encountered.
  I also received a replacement switch put the problem was always the same (latest firmware from the website, etc...).

  After hours of troubleshooting, I discovered that it is related to the switch cascading behind it.

  This GS728TP was connected on a GS724TP, both are POE switches, I disabled the POE feature on the two switches on the ports used for them and no problems cascading more.

  I don't know if you've had the same configuration, but in my case, it is now resolved!

  Kind regards.

• HP ProCurve 1800 - 24G of cascade switches

  Hello

  I have the following problem. I would like to connect/stack 3 switches not by RJ45 cables copper (which I do now), but by a cascading system or optical cables. In fact, I would have preferred cascading but I don't know if this is possible with my devices. My system looks like this now

• The proSafe (JGS524E + GS116E) Switches: Configuration Management Web GUI in VLAN specific

  Hello

  I use a JGS524E and a GS116E. The two are connected via a 802. 1 q uplink with all defined VLANS in him.

  A 802. 1 q other interfaces goes to a pfsense firewall, which serves as a router and dhcp server for each VLAN that I use.

  How can I configure the switches plug are in one VLAN specific and get his IP address of the dhcp server in this VLAN?

  At present, it seems to be random access: it is not predictable that range from intellectual property, it takes its IP configuration via dhcp...

  How management function works internally?

  Thank you

  Markus

  Hello

  Thank you. I tried it out, but the behavior seems to be a little different:

  I configured a static IP address for the switch (10.1.0.13 / 24). I have access to the switch web gui via the ip address of the host of a host directly connected (connected via a trunk port, where I put 1 VLAN on the trunk), but it is all the same, what VLAN that I use:

  When it is connected to the VLAN 1 I have access, but also through 10 VLANS, VLAN 20 and so forth (assumed, I configure my computer appropriate staticly in the IP network, for example 10.1.0.20 / 24). So it seems not be limited only to the VLAN 1. You have access to each vlan, only the IP configuration must be in the same network.

  I'm not sure, how it behaves when cascading the two switches, I have not tried.

  If this information can be useful for other users with the same question about this switching product line.

  For me, this behavior is not very well implemented from my point of view. For security reasons, you must limit access to the administration, for example by allowing access from a specific hardware port or a vlan. With the effective implementation, centralized management for a cascade topology is not easy to set up, perhaps because the behavior is not very clear and not documented in the manuals.

  Mentioned on the edge: there is no available TLS/SSL encryption when accessing the web gui (not https). So the password is transmitted in clear text... not a very good idea, I think.

  Thanks a lot for your help.

  Best regards

• Linksys E2000 to into acccess point/switch helps.

  Okay so here's the deal, we got At & T Modem/Router upstairs, and then we had a long cable ethernet connecting here in the basement. The problem is that this allows only a connection to the local network at the same time (a problem for LAN parties and others). I do have a Linksys E2000 router however and I want to be able to use it as a switch access point.
  I'm sure this is possible, but I forgot all the steps to do so.
  The att modem/router is running on 192.168.1.254 and my Linksys that is directly connected is on 192.168.1.1, so I have another address in this field.
  What I need to change my Linksys settings now, or do I have to change the settings for at & t?
  Basic steps would be appreciated, but I am familiar with the concepts of normal network, so you mustn't it level by the low that much.
  Also I will use this for Xbox Live at points so will I need to re - open all the ports on my Linksys, or at least put the DHCP to static IP Xbox to keep my NAT good?

  Thank you

• How to implement as a router WRT54G - Type of Internet connection in cascade

  Dear Sir / Madam

  Been scouring the Internet and seems that nobody begs the question...

  I'm trying to configure my Linksys WRT54G (v5) as a regular secondary router (turn off wifi) cascading off my another Wifi router that is connected to an internet modem.  I went through the web and found useful points on other areas of the installation program.

  However, in the "Basic settings" page under "Setting up the Internet" for "Type of Internet connection", what should I choose?  I am NOT connect the WRT54G to the internet modem, on the contrary, I'm linking to the internet via my primary router.

  Help, please!  Thank you!

  Simon Mak

  Hi, simon_s_mak. Yes, you can set it to auto DHCP. It wouldn't really matter, since the DHCP capability will be disabled.  Therefore, it will exercise a switch only.

• Cascade 2 routers?

  New to the forum, so I apologize if this has been covered. He's probably, and if so the directions to the correct thread would be appreciated.

  I originally installed a router Linksys 4 port in my house. When we had this House built I wired it for ethernet myself. The point where the router is installed is very close to what the phone company bark when she enters the House. Problem is back, then wireless is a thing of the future, and since all ran on cable it did not matter that this thing was off at one end of the House.

  Now, it is important, because with the advent wireless, I upgraded to a Linksys WRT54G2 a few years ago (I think). But I'm developing 2 new problems. The first (1st) is that I've not enough ports to support all the devices wired, we could have connected - I'm flat out ports and need at least 2 more. The second (2) problem is the wireless signal is just low enough to drop signals on some devices within the confines of our network. Most work well (laptops), but some do not (Kindle, smartphones).

  What I want to do is to install a new router 8 ports to the current location of router (problem 1). I want to spend the WRT54G2 existing at a more central location, then plug it into the first router that I hope will solve the problem (2).

  I would like some advice on which router to buy 8 ports, and any advice on the installation of a system of cascading of routers like this.

  It seems that I see today are wireless routers. If the new 8 port router is a wireless router it will interfere with the other wireless router or can they be used together to boost the signal still more?

  Thanks in advance for any help you can offer!

  1. for reading: http://homecommunity.cisco.com/t5/Wireless-Routers/Connecting-two-routers-wired-the-definitive-answe...

  2. you don't want to buy a router 8 port. You want to buy an ethernet port (or more port) switch 8. An ethernet switch extends the network wired with additional ports.

  3. If you need better coverage get an access point or router (set up as access point).

• Should switch BEFSR81 - wireless access point I use?

  Hello

  I have a cable modem connected to a Linksys BEFSR81 switch under the stairs. It distributes points of LAN cable to every room of the House - it worked perfectly for years and continues to do so.

  I need to add wireless (for iPhones etc.). I connected a Netgear WPNT834 DSL wireless router in a LAN points. It broadcasts a SSID I can 'see' on my iPhone - I can connect to it, but cannot access the Internet.

  Looking good, I found the two devices by default the IP 192.168.1.1, so I changed the IP address on the BEFSR81 on 192.168.1.2. Still no access to the Internet via the wireless Netgear.

  I guess that there is a relationship between the two devices share the bandwidth, but I'm at a loss to know where to start.

  These two devices are not compatible, or is there a way to their cascade work together? Or, is it a point of access wireless (linksys or cheaper universal device) that I can plug into one of the LAN edge to add a wireless network to the existing local network?

  Thanks for your help.

  Hi Mikey'it,

  The Netgear and Linksys are compatible when you want to set up this way. You must configure the Netgear router to a wireless switch. As disable the "router" function and DHCP. You must ask the Netgear support how to do it. Because the Linksys router works perfectly, you need to change anything.

  

• Cascade 2 WRT300N and have both sends a wireless signal

  I searched the forums, discover different cascading routers and posed this question in a different way, but I don't know if I'll be able to use a 2nd WRT300N in order to broadcast a wireless signal if I connect it to my 1st WRT300N. Routers will be connected with about 50 ft 5 cat. Is this possible? I connect the ethernet port to the port ethernet or go eithernet port 1 to the WLAN port on 2? Any help would be appreciated.

  1. you're not technically a wireless router but only one wireless access point. A WAP610N or similar would be the better choice in this case.

  2. you can use a router as a simple access point and ethernet switch. Change the address LAN IP of the second WRT to 192.168.1.2 192.168.1.1. Disable the DHCP server on the second WRT. Then, connect the two LAN - LAN. Do not use the internet port of the second WRT!

• VLAN in PC5548 - is required L3 switch?

  Hello fellow networkers,

  We have 4 PC s 5348 and several 54xx L2 switches used for desktop computers, printers, wireless APs, servers, etc. - without reflection or reason as to which is connected to a particular switch - has increased over time as many companies.

  Due to the audit of security, we must now separate the data traffic. desktop computers, wireless etc. and implementing local area networks virtual.

  We have 2 PC 5548 s recently bought to vlan servers with a cluster connection cascading other switches that will be take place computers in office, warehouse, printers etc. We were told the 5548 s also support features of L3, but reading of the record, it appears that they have no L3 routing function

  Simple question:

  Can the servers (on 3 VLANs) + 1 connection with any other switches, being able to communicate with each other on the 5548 s or will we need to have a L3 switch?
  (Our thoughts were that all ports may be able to communicate if they share the same vlan extra)

  Thanks in advance for your help

  Bill

  The 55xx series switches support the IPv4 routing and can be activated with the command,

  #ip Routing

  However, it does not support routing VLAN. You will need a 3 layer switch that supports of VLANS, routing, 62xx, 70xx, 80xx, 81xx.
