Troubleshooting Network Card Issues in Fedora

[redwarrior]

Hello everyone. I got a bad early Christmas present this morning...my integrated network card is showing a steady amber light and I have no network. I've already swapped cables and made sure my router is working fine, so I've isolated it to either the actual integrated NIC or else software on the PC.

I've run ifconfig and it is only showing a IPv6 address, which is strange since I'm not running IPv6 on dhcp on my router. I've tried bringing the device down and back up hoping it would grab a good dhcp lease, but no dice. I'm planning on going out and getting a new card and seeing if that resolves the problem, but I was curious as to what other troubleshooting steps I could do from a Linux point of view.

If I were using a certain product from redmond I would probably do a "repair" on my connection which would flush all caches and do a release and renew in dhcp. I was wondering if there was a similar option in Linux. I'm also wondering if some network cards work better than other for Linux. I'm running a wired connection from my Linksys 802.11g router for this particular PC and my current integrated NIC is an Intel that is built into my Dell mobo. I have plenty of spare PCI slots, so that's not an issue. (Although keeping myself restrained to just a new NIC might be. ;) )

Thanks for the help...I'm still learning!

Any chance that the nic could have somehow become mysteriously disabled in the bios? Have you checked?

Also, as root user and in console, type the command:

lspci

to know what card are you using. Put the output here.

Turns out it actually was a dying onboard NIC. I bought a new linksys, disabled the integrated NIC in the bios and poof! Network lives. It does make me wonder about the health of my motherboard, though...I'm hoping if it goes that the power connectors and such aren't too proprietary...darn dell! :rolleyes:

Thanks for the help, though, guys...I'm still finding my feet in the Linux world!
