A network cable is unplugged

Make sure that the cable is not plugged into the uplink on the router. That it is plugged in to a numbered port.

I DON'T THINK YOU CAN RUN 2 ROUTERS ON THE SAME NETWORK UNLESS ONE IS USED AS AN ACCESS POINT.
1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).

3. Disable DHCP - To avoid IP address conflicts between all of the devices on the home network, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.

Instead of adding a second wired router to an existing network, consider adding a network switch instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying configuration.

you will need to connect direct to your router to figure this one out.connect a network cable from your laptop to your router port 1,2,3 or 4. now open internet explorer and surf to (instead of www) type 192.168.0.1. you should be prompted for username and password. try the were, try admin and leave the password blank. you can configure your wireless settings tab in the web interface. try using settings WPA or WPA 2 and make up a password., once complete. exit the interface, unplug and see if you can connect with your password you set. Note. its a good idea to change the routers defaut password if not done yet.

Here's a link to the Cisco (Linksys) site with directions on how to connect your range expander.

Hi, either there is a broken cable or faulty connector some where or the Lan card in your pc is faulty.

1/ Check all cables
2/ start with one router and connect that up by its self, without any other router.Connection should be made as close to the pc. You know the usual setup, modem,router,pc.
We are trying to narrow it down.

If pc still says network cable unplugged then make sure the lan card, in your pc is seated properly.Are you using a seperate lan card or the the motherboard connection.

I have just found that this product was discontinued in 2003,you are probably better of buying a new one.

But any how let me know how you get on.

If you are connecting to the Internet using a wireless connection and your LAN card in the computer does not have a LAN cable connecting it to a hub or router then you will get a message "A network cable is unplugged".
If you don't use a wireless connection and you only connect to the your network/Internet then the problem is either the LAN cable has come loose in the computer's LAN card or at the router or the LAN cable is faulty.

Most likely the connection inside your new gateway is bad - you should return it under warranty & get a new one.

I would start with the simple things first:

1) reseast the ethernet cables
2) change the ethernet cable
3) change to different port on the router
4) uninstall/reinstall drivers
5) run spyware cleaner and anti-virus

this is something simple
2 things you will have to do

the router when a problem like this happens again
unplug router for 1 minute this is packet build up and then plug back in i found this out by service provider that its a build up of packets it relieves packets

now the other thing since you went threw all the little areas of trying to reset modem go in remove your network connection
delete it and build a new network connection threw the network setup wizard then your done restart comp everything should be back to normal and you wont have to ever reset network settings again
just unplug the router let sit for minute and plug back in

mairelina, if all was well 2 days ago then resetting the router should fix your problem. usually a small button on the back of the router.

chelliepooh, you need to check that the router's wireless function is on. connect using the ethernet and go to the config page (usually 192.168.1.1) make sure wireless is on and security is set to wpa-psk.
