Cisco WAN :: 2611 - Connecting Home Lab Router To Cable Modem Over Wireless Access
Mar 11, 2012
My home lab is in a different room than the cable modem. I have a wireless N router in the room with the cable modem. I have a wireless access point that is connected to a Cisco 2611XM routers fa0/0 interface. The 2611 accepts the DHCP address from the wireless router. However, I can't ping past the wireless LAN 192.168.10.0 network. I know with the wireless router it's two layers of DHCP. Should remove the DHCP settings from the wireless router? The wireless router is a TrendNet TEW-651BR. I can ping my iphone or any device conntected to the wireless router. And my laptop can ping default gateway of the wireless router, which I assume is the cable modem, however the 2611 cannot. So I'm assuming that's why the hosts behind the 2611 can't get to the internet. I followed the below instructions. I know the instructions don't assume your using a wirelss router between 2611 and the cable modem. But, I really don't want to run a cable to the cable modem.

I am with Virgin media and have a home lab (2611 routers, 3550 switches, 2950s etc) which i usually just use for testing things on and practicing.
Now I tried to connect it to the internet and got some weird things happening.
I got NAT and DHCP client all setup correctly on the router (or so I think!) along with DNS settings but I still can't get Internet access.
My network is all setup right so that through using OSPF the router is the gateway (0.0.0.0 route) for all devices. Doing a traceroute confirms this.
Yet I never get any further than the router? I see IP nat translations ticking up as I send more requests but never get a webpage or a reply from any of the machines in my network.
HOWEVER... The router itself does get some replies from Google.co.uk and bbc.co.uk but doesn't seem to want to give anything else on the "inside" a response?
Here is a dump of config:

I'm trying to connect my Cisco lab to the internet. I've configured my 2611 to accept DHCP. I can ping the Linksys E1000 router but can't ping the modem on the other side, and cannot get out to the internet with the PC that's connected to the lab. When I look at the DHCP table in the E1000 the 2611 shows up in the table. I can ping all other computers on the lan, just not the modem to get out to the net.I have the configuration for the 2611. Did I miss something. Is the modem blocking ICMP traffic?

Have had ADSL installed through a router, connected the wireless router and it works fine Have since connected the original router via -120mtrs of CAT5 cable to extend to the house. Connection through LAN is fine into desktop however the minute we try to connect an additional wireless router the connection fails. We have even put the LAN from the second Wireless into the desktop and there is no connectivity.We have had a technician come to sort the problem, they advise that they have no explanation as to why the LAN works from the distance but the wireless does not. They have suggested that we need to cut the CAT5 half way and put an antenna up to connect the two routers.

I am trying to connect a Netgear wirless router to my cable modem. I have followed the instructions on the set up wizard but it fails to get a connection with the IP and DNS info I provide.I got the IP address info by connecting intially direct from the modem to the PC and then went to Run CMD and type ipconfig /all. I then started the set up wizard and followed the instructions, turning things on in specific order etc. After input the IP and DNS info it reports an error and tells me to check the address information is correct.My internet is a static IP connection (so it tells me and the IP information doesn't change).

I want to create a DMZ by having a less sophisticated router connected to cable modem, which would have the webserver which contains no sensitive information, and then the EA3500 to which my laptops and desktops which contain sensitive information would connect to. Can CCC work through that first router?

Lately I've been experiencing connection problems between my router and cable modem. Every night after 11:00 PM EST, my Internet connection sporadically goes out. I called my ISP who said there was nothing wrong on their end. Plugging directly into my modem allows me to access the Internet. When I wake up in the morning, the connection is back until 11 or later again. I ran WireShark but I'm not sure what to be looking for. There are a lot of random things from the LLMNR protocol like standard query A zmtvrjaql.

Management has decided to put in a Wireless network and want to keep it sepeate from rest of the network. I have been asked to scope out DSL/Cable internet connections.
I am not familiar with setting up 2504 with dsl router.
Any basic guides for setting up 2504 with a dsl? do i need any static ip addresses for this setup or dhcp lease provided to cable modem would do?

I have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?

I cannot access my Motorola SB6141 cable modem status page at 192.168.100.1 thru the EA6500 router. I can bypass the router and can connect to the status page with no problem. Is there a setting to change or can I possibly do port forwarding to access it?

What I learned was it was bad to connect directly to the modem because you are left open to the internet. Currently my friend just got the internet and I told them to buy a router but they did not, and just have it directly connected to the modem. Is this fine, because they only have one computer, and it works fine for now, but wouldn't this be prone for attack?

The network card in my PC supports 1Gbit ethernet, my 2TB NAS also supports 1Gbit ethernet, however both of these are currently run through a 100Mbit cable modem/router thus reducing the connection speed. I was wondering if I purchased a 1Gbit switch and connected all my devices directly into that, then connected it into the cable modem, would the PC communicate with the NAS directly via the switch or would it go through the cable modem?

I have a 3560 series switch and two comcast cable modems. I connected the modems to them switch via cross over cables and set an OSPF routing on their subnets. I connected my wireless router to another port of the switch and set its gateway IP on the switch port. I can ping the modem with the switch and I can ping the wireless too. But I cannot access to the Internet via the wireless router.
I need load balancing on two cable modems and get a single network connection via the wireless router.

Ambit U10C018 send light not working. All other lights indicate proper functions. Usb not in use or connected. Enet, power, ready, receiving and sync all appear to be working properly. Have rebooted both modem and computer countless times, replaced Ethernet card (DFE-530TX+(Rev f), checked cables, all appear normal. Suddenlink service, cable guy didn't locate problem (didn't try very hard either).

I've never setup a router before, but when I tried to setup this one it required me to put in the isp ip, subnet, gateway, and dns. I assumed that this was not my ip but the ip of zoomtown which when i looked at the old routers info i figured this was the ip under the configurations summary that said wan ip, perhpaps i was wrong, i'm not sure but this ip info is static it does not change , but I believe the individual computers ip addresses use dhcp and are not static.

I current have a Cisco 2100 Cable modem (192.168.100.1) connected to a Cisco Linksys E2000 (192.168.0.1) that is connected to a Cisco 3550 (192.168.0.10). I would like to relocate the E2000 to another room. This would require me to connect the 2100 and the E2000 through the 3550. I have had to set a MAC address clone on the E2000 of the PC that is also connected to the 3550.
The question I have is how do I get this all to interconnect so that the E2000 is used by the 2100 for validation to the internet provider (Time/Warner). I am also using the E2000 for DHCP.
Here is a copy of the running config:
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime

The detected problem is the connection between my access point, router, or cable modem and the Internet is broken.The network gateway is accessible, but Windows couldn't receive network traffic from the Internet.All other devices (iPad, Xbox, android phone) have no problem connecting to the Internet.Desktop is the only one experiencing the connection issue.

My laptop died last week and have been using my husbands, which I hate! We had some issues with computer freezing on some webpages or after being on webpages for awhile (like facebook). Yesterday it froze and I could not get it back on. When he got home he did scan disk (which I also did) and got it working after going into safe mode and doing system restore. He said an update had gotten through and messed things up. Anyhow, after he was on it a few hours last night, we lost connection. I figured the crazy weather was the culprit but it has been off all day. Our router is working and connecting but the adapter is not. Also our home phone says there is no line. We have unplugged everything several times, checked to make sure everything is in the right spots, I have even reset the router and rebooted the adapter. I uninstalled and restalled the adapter also. It is now telling me that "the connection between your access point, router, or cable modem and the Internet is broken". The only lights I have on the adapter are power, battery, DS and now the US light is blinking. The online and link lights are not on.

I can't get a new IP from my ISP when my Cable modem router(EPC3925) is set to router mode, i have tried factory restore, unplugged etc..but still no luck. It changes each time i reset it when i set it to bridged only mode but then i won't be able to connect other devices to it since it doesn't uses DHCP in bridged only mode. It changes back to the IP i had when i set it to router mode. I don't want to change my router settings to bridged only because it would disconnect the other devices in my house. Why my ISP assigns the same IP address when it's set to router mode but assigns different IPs when it's set to bridged only, how is this possible ?

is it possible to connect the wan port of a cable modem to a lan port of the home network? the reason is, i need some wifi access and more ports to my wired network, and the most reasonable solution would be a cable modem router with wifi and 4 ports just plugged into one of my routers.

I have a Thomson TG585 v7 router which is in bridge mode. I also have a NetGear DGND3300v2 router which I would like to connect to the Thomson (eventually I will purchase a switch and connect another device along with the NetGear). The problem is that the NetGear only has 4 LAN ports and no WAN ports, which I assume you would need to set this up.

I've been given a used Dell Latitude laptop and need to access the web to register Microsoft Office, which is currently unlicensed on my machine. I took the cable connector from the back of my PC and put it into the port of the Dell, hoping that that would be sufficient. However, it doesn't connect. The gubbins that is displayed for the local area connection status says something about 80 packets sent and only 8 received.
