I have a Linksys BEFSR41 router connected to my computer with a cat5e ethernet cable. But the port indicator light on the router doesn't light up and ubuntu says no network device is available. I am running 8.10 on a dell desktop and the cable is connected to the built in ehternet port.

maybe there's something with the wiring,specially that the light in the router isn't on

The cable is plugged in to both the router and computer and I tested ithe cable with another computer. I think the problem could be that ubuntu is somehow not detedticing the ethernet port it says unable to detect any network device.

Do you have a cable tester? I think it's a bad cable.

Then a bad NIC

Or a bad port on the router....provided that the ethernet interface on the computer is actually enabled.

Might be none of those things.....might be the driver for your NIC. I have had problems ever since I went to UBUNTU 8.10, it installs the wrong driver for my RTL8101 NIC. I have been going in circles trying to get it configured where it will even see the 'network device'.

Nope.
A functioning NIC will always light at least one LED when a functioning cable is connected to another functioning device.
OS or driver have nothing to do with this, it is hardware.
So if the LED is not lit, that means it's definitely a hardware issue.

So its probably a hardware issue and I still have warranty but I would have to reinstall XP to get warranty service. Is there a howto on installing windows without wiping out ubuntu?

I think you will find the default ip address is the same on the network card and the linksys befsr41. In windows you have to change the address of the router to 192.168.2.1 instead of the default 192.168.1.1. to get the system to work with this cabel/dsl router. Then the ip address of the computer has to be released and renewed. Linksys has a q&a on this procedure for windows I was looking here to see if anyone had done it for Linux. Reboot after you change it and everything should work fine. I have this same box and I was looking here to find the procedure for doing just this when I stumbled over your post.

the problem was that the integrated NIC was disabled in the BIOS setup.
