• How can I connect a cisco router to the internet via a cable modem / router gateway

  I have searched here but can't find the exact answer that I'm looking. I have a switch and a router cisco 1760 2950. The router has an added ethernet wic card so I have two ethernet connections available. I would like to connect the cable modem gateway the router through one of the connections on the router, then the switch ethernet. I can't get this configuration to work. There are several different ways, I saw displayed to accomlish. DHCP, without dhcp, creating a separate network and giving the e0/0 cable an ip address in the range of addresses network gateways. None of this has worked. Can someone after the commands that must be entered on the router to make this possible?

  Hello, I'm assuming that your ISP is to give addresses via DHCP...

  And I suppose also we want to implement our router DHCP in our local network to give our PCs and laptops etc...

  So what we need to do is:

  conf t

  !

  interface e0/0

  Description # INTERNET #.

  IP access-group MY_WAN in

  DHCP IP address

  NAT outside IP

  No tap

  !

  interface e0/1

  # MY LAN description #.

  IP 192.168.1.1 255.255.255.0

  IP nat inside

  !

  IP access-list standard MY_LAN

  permit 192.168.1.0 0.0.0.255

  !

  MY_WAN extended IP access list

  allow tcp any a Workbench

  refuse TCP a whole

  allow an ip

  !

  IP nat inside source list MY_LAN interface e0/0 overload

  !

  IP dhcp excluded-address 192.168.1.0 192.168.1.99

  !

  dhcp MY_LAN IP pool

  network 192.168.1.0 255.255.255.0

  default router 192.168.1.1

  Server DNS 8.8.4.4 8.8.8.8

  In this configuration, I applied an ACL for a protection to my router and my network to allow only established connections that Ive from my LAN to return to me. Anyone who tries to open a connection to your router will be refused. Everything is allowed. But you can change this option to be more specific rather than wide.

  On your switch, if you leave all ports in the vlan 1 and have as access ports, it should work.

  Hope this helps

• Need a cable Modem (have an Airport Extreme)

  I am a subscriber of internet high speed from Comcast in the Chicago area.  I have their most recent Wireless Gateway that supports the 802.11ac fall on my newly upgraded Airport Extreme.  I'm looking to buy my own cable modem and seeks recommendations based on the information.

  Anyone who wants to help out? Thank you!

  In fact, I would like to start with modems that that Comcast will be supported. The only ones you should avoid a potentially are the Arris / Motorola SB61XX-series modems as they have been known to be incompatible with airport base stations.

  For recommendations, I suggest you Cisco, as the DPC3008 models.

• XP using a Dhcp Server if you have a cable modem. This is a Must?

  XP, network, Cable Modem. Do I have to use DHCP because I have nothing between me and the router? I watched hours of stuff on networks and nobody don't never went that far in anything. According to their patterns, Cisco or other, passed between their machine and the cable box. I've set up with static addresses (most of filmmakers disliked that sceme) and everything seems fine, but I have several others [don't know what to back]. To begin: Net bios on TCP/IP, WINSOCK, do I need? Well, I should have tried to find it, I should have written it down before I got here. Is it possible to save a project to the present, and I can drive around the site for a while? Now I get all these good advice from Youtube, and I bet everyone's probably laughing at me because you get ten different opinions to the same question. I have to add this. You can add memmory to your system for free! Yeh, you just go here and change this figure there, bam, more memory (long live Ram). It took a while, but for some, it may be a joke, but sometimes I can't tell when they're joking. Yes, I'll change a few settings. OOOPPPsss. Spybot, Ouch, he hacked me upward when I wasn't looking. DNS servers... Monitor drive..., the link layer,... .packet scheduler and now all of a sudden the TCPIP6 is suddenly. I've never seen a video on any of them, except 6, they were running 8.1. Cool. I hate just to bog down everything by adding all these other things if I don't. My settings seem to work very well, but sometimes things get a bit dodgy. Affecting those other things would make the program more stable, faster, or it's just the way it should be done? I hope all of you can remember when you have no idea, "what the hell do I need a Winsock for? I live in the desert.

• Can I connect printer to the usb port on the cable Modem CM100

  Hello

  This may seem like a stupid question, but here goes... I know that the usb port on my Linksys Cisco CM100 cable modem is an optional way to connect the modem to the computer. I wonder if I can use the usb port to connect my HP 1020 laser printer instead.

  The printer is not a network printer, and so I know that it may not work, but I have seen a few cases where a virtual port and install it as a local printer got to work.

  If I can connect the printer to the modem, and then he would give me a way to print from my laptop in the other room.  My printer is just beside my modem configuration and the router. I have a Linksys router WGR614 wireless who sees the devices on my network share, so I think he could see the printer connected to the modem (?)

  I couldn't find the answer to this anywhere. I didn't damage my equipment by blindly try this without knowing a little something. (I assume that the heart of my question is, on the CM100 usb port can be used for any usb device)?

  (I have Windows 7 64-bit operating system, in case you need to know).

  Thanks to anyone who can answer.

  A standard print server will allow you to connect a USB printer to your network. There are models wired and wireless depending on how you want to connect to the network.

• E4200 and Arris TM702B cable modem

  I bought this router and expects a lot from it, but not what happened when dl a file: its starts enthusiastic and reaches up to 8000 Kbps, but unfortunately my cable modem loses internet contact then (seems to reset or accident or both). My network is fine, it's just the internet connection.

  I have updated the firmware of the E4200 (FW_E4200_1.0.02.013_US) and reset the router: no joy.

  Claimant stated that my modem is OK, but that leaves me with this annoying problem!

  Can someone help me please?

  Try these steps-

  Move the far the arris of telephone cable modem router... use of cordless telephones 2.4 Ghz also run a speed @ speedtest.net test and a ping test @ pingtest.net, and also keep all wireless phones away from routers, I found a huge improvement in my router speeds and no lag or dropped connection! also tips to improve your speed-

  SAVE THE SETTINGS

  access the router to change these settings - type 192.168.1.1 and enter admin, and the password (that would be your router password) or cisco software click router connection settings then click on advanced settings, then click ok, and then manually configuring the router

  This should also improve your 5 GHz & 2.4 Ghz speeds and make sure you have wpa2 password protected it and I am sure you will find a shocking improvement as I did in the speeds and singal...

  you will see a significant improvement in singal, I discovered cela if trail and error even had cisco replace my E3000 due to connection problem when all along, it was my cable modem wireless!  I would come down the router about an inch or more away the ARRIS cable modem! Good luck! my router went from 54.0mbps to improve 144.0mbps - so try to move the router away from the modem, it worked for me and there is a difficulty

• Cable modem link slow w ISA570 and CLI 'See the tech' equivalent

  Hi, I'm hand non-profit that has a link to 100mbs Mediacom, they get 90 + speed connected directly to the cable modem, but anywhere past the ISA570 they get only 50-60mbs. They spent the cables, added a port separated, tried different PCs, the results are the same, 50-60 MB max. In addition, it is their understanding that the ISA570 cannot do CLI, so how can they get the equivalent of a 'show tech' command in a file to be sent off site for troubleshooting, thank you. Jim

  Hello

  Is there something similar to show tech CEP.

  Log in to the web site GUI, go to device management > Cisco Services & support > Send Diagnostics.  At the bottom of this page is a download button that will collect the configuration file, newspapers and some outputs debugging in a zip file.  You can use this to troubleshoot the device, even though I generally prefer to be the device live webcam himself to see things.

  Before digging too deeply into those however, what type of security services currently have enabled on the ISA?   I was looking on the Datasheet , and even if the SPI is capable of ~ 500mbps, when you start to enable security services these beginning of speeds to drop.

  If we look at the flow measurements UTM (Unified Threat Management), which is roughly of 75mbps, which is pretty close to what you have found.  I go and disable various security services one at a time and test your speed.  My guess would be either A / V or IPS slows down your connection.  It can be one or a combination of these services, causing the slowdown.  You can disable these options, or just explain the extra security will cost a bit of speed.

  Hope that helps a little,

• cable modem-wireless combination or not?

  Hi, I'm going to switch from DSL to cable T - W (the only option in my building). I have an Airport Extreme on my TimeCapsule (it is the 500 GB disk version), that I use with my laptop. The iMac is connected to the router. I looked around at best buy where they sell T - W "approved" networking gear. Modems cable, all seem to be modem + units of combination of WiFi router at various points in price between about $80-200. My question is this: that any type of material that I use as long it's T - W compatible/approved. Any thoughts on the units of combination or is a cable modem + my Airport Extreme way to go. Not sure of the speed yet, but it is unlikely that I will contract for what that either more than 50 Mbit/s and perhaps even to 15 Mbps. Support some of the Motorola units that I was looking for very high flow rates, but they use the channel binding to achieve this goal. I read somewhere that if you buy the combined devices, you cannot update the firmware, but that doesn't make sense to me.

  Ask TW a modem without router built-in. And then run an Ethernet cable from the Ethernet port of the modem on the WAN on your AEBS port. You can connect your computer to the router either wired or wireless. It is the best configuration.

  If you do not need for Ethernet, then you can use a modem cable with router Wi - Fi as well. The main disadvantage is the difficulty you might have try to expand the modem/router using Apple hardware.

• Connect the Airport Extreme via Powerlink to the cable Modem

  I have problems with wifi at home as the location where the my cable modem is far from ideal. I currently connected to an Airport Extreme, which works like the router (the cable modem has the router function disabled). Attached to the AE is also a powerlink and I have an Airport Express connected to the powerlink, which has its own network.

  I was wondering if it would make sense to connect the powerlink directly to the cable modem and then put my Airport Extreme, a more central location in my home connected via Powerlink and there accumulate this way, rather than the current configuration.

  I'm getting a second Airport Extreme soon as well and I have several express in my house, but the problem is that my wifi is not fast at all.

  Powerlink adapters are Devolo 600 & 1200.

  Thank you

  I was wondering if it would make sense to connect the powerlink directly to the cable modem and then put my Airport Extreme, a more central location in my home connected via Powerlink and there accumulate this way, rather than the current configuration.

  It's always a good idea to place the 'main' AirPort router as close as possible of the area where most of the wireless devices should be used in this sense, your idea is a good thing... and in theory at least. ... .the powerline adapters allow you to do.

  However, in practice... you won't really know how well... or even if... this type of installation will work until you try you. The reason for this is there is so many different things that can affect the performance of a type of current line of the installation program.

  If you have time, there is certainly no harm in trying this type of configuration.  Post your results if you decide to try it.

• 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

• Time Capsule do not pick up address DHCP and cable modem...

  You just bought a Time Capsule and a couple of Airport Express. If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  That being said, I tried to create a mobile network instead of pure wi - fi and am studying various behaviors that are not as expected when I rear hub to the Internet Time Capsule, but need to isolate and go 1 bit at a time... (it works not as well as suggest Apple instructions on homelessness of installation)...

  If:

  1. configuration of the modem cable shows that DHCP is 'ON' and supplied address range 192.168.0.x by 192.168.0.y,.

  2 Cable modem wireless is disabled,

  3 Time Capsule Wan is connected to the cable modem, Ethernet

  4 Time Capsule is configured to request its address IP, DHCP

  5. Airport Express is in Bridge mode and have addresses such as 10.x.y.z (appears to be from a Time capsule).

  6. safe as Time Capsule is set to be as DHCP and NAT

  7. There is NO other device in this configuration connected by Ethernet except the cable Modem and the Time Capsule.

  So, why is the IP address of the time Capsule 76.181.45.xyz? (The address is NOT in the range of the DHCP as described in the #1; it is not supposed to be?) ....

  Whence this address?

  A friend says this address puts the "other side" Time Capsule of the cable Modem, directly on the Net?... (Shouldn't worry?) ....

  If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  It's because you didn't have the devices connected via Ethernet before you set up the. Given that the installation utility saw a wireless connection, it is assumed that this was the way that you want to connect devices on your network at all times... so he put it this way.

  If you had an established connection Ethernet before you ran the installer, then the utility would have detected this connection and set up the airport to "expand using Ethernet", does not extend to assistance of wireless.

  (it works not as well as suggest Apple instructions on homelessness of installation)...

  If all goes well, you don't talk about this document... Wi - Fi base stations: extend the reach of your network wireless by adding additional base stations Wi - Fi - Apple Suppo... .. Since the 'how' information in this article is at least 4 years late, bear little resemblance to the latest version of AirPort Utility and some of the information are simply not true.  This document if trash is what you... He'll probably do more harm than good with regard to the details of setting.  The article is OK for basic general information, however.

  6. safe as Time Capsule is set to be as DHCP and NAT

  It should not be if your modem is a modem/router "" or type 'bridge' of the device which is also DHCP and NAT services. The fact that you have disabled the wireless on the device confirms that it is both a modem AND a router. That being the case, then you have two devices that both struggling among themselves to try to control the same network... AND do you also have a network error called Double NAT... something you don't want.

  Probably the best at everything again and provide us with the number of brand and model of your "modem", that we can confirm what it is that you have, then the correctly configured time Capsule to work with this device. Once the time Capsule is set up correctly, it will be easy to put in place the other airports.

• Time Machine and Motorola SB6141 cable Modem is to create an internet break

  I had a SB6141 since I got cable internet 1/2014.  I had hung by a former Airport Extreme Base Station - it was all good.  I bought a time machine from Apple refurb > 6 months ago but < 1 year ago.  I had injury disruptions of the internet - I only know when I try to access the internet and airport utility shows time machine ok, but the router cable not connected.   I called the cable company, the last time it happened, and they showed the line was ok and had me hang directly up to the cable modem to get online - and I did!  They think that the router is messed up.  Once I unplug everything and hang it up, everything is ok.  Sometimes it happens one or twice a day, sometimes not for a week, it's not rhyme or reason - anyone have any ideas?   Thank you, Mike George

  The SB6141 is a good modem, and airport Time Capsule is a good router. But they don't seem to work together that well for a number of users including me.

  Make your choice... keep the modem and try another router... or... keep the time Capsule and try another modem. As soon as you make your choice, the faster your chances for a reliable Internet connection.

  You are not alone in your problems.  Take a look at just a sample of other users who have posted the same question:

• NETGEAR N300 Wi - Fi DOCSIS 3.0 Cable Modem Router (C3000) sees the backup HD Seagate but don't transfer

  V1.01.11 firmware, OS is Windows 10

  I bought the cable Modem Wifi Netgear N300. Except for the external hard drive Seagate (backup Seagate more 5 TB desktop external hard drive with 200 GB of Cloud Storage & Mobile Device backup USB 3.0 (STDT5000100)), all my devices connect to it without problem. However:

  1.) when I have the hood upwards the Seagate external hard drive, the genius of Netgear he sees, but says that the drive has 0 bytes available.

  (2.) that's why I can't back up by using the backup program WIndows 10 but

  (3.) I can "manually" drag files from my PC to the Seagate HD (the PC is connected to the modem router cable via wifi.)

  4.) when I connect the Seagate HD with a USB cable to the computer, the backup works.

  It's frustrating because I want to use the Seagate HD as a backup for some of my devices and I want the devices to send their data or the Netgear router.

  Can someone help me? It seems important that Netgear genius sees the HD Seagate but think it has no place.

  Richard

  I answer my own question (!) but is the answer that the HD 5 t is not compatible with the cable modem Netgear router? See:

• Cable modem of CM600 default after large downloads

  Hi-

  I use a CM600 modem with a router WNDR-3700v4.

  Recently, the cable modem has started to behave very strangely after the download of large files (1 GB or more seem to be the trigger point). Once the download is complete, I started experiencing excessive latency and packet loss to external sites. Ping times jump around 20ms for 3000ms and package loss ranges from 0% to more than 50%. Restart the modem cable does not resolve the issue until I download another file of large size. Interestingly, I found that if I disconnect the cable modem LAN cable when it is defective, the modem still shows an activity and a LAN link on it. I expect the activity ceases when he is physically disconnected and link drop. I swapped the ethernet cable and it made no difference.

  If anyone of you thin people have ideas?

  Thank you very much!

  The modem has been replaced and the problem disappeared. Yay guaranteed.
