You'd think what used to work wtill would, but...
Check (post if possible) sud lshw -C network to see if interfaces are recognized and ifconfig -a to see if they have IP address (probably won't...)

Dear Iowan,

I have the same problem after upgrading to Karmic.

My interface is recognised. This is the results from sudo lshw -C network:


*-network
description: Ethernet interface
product: NetXtreme BCM5754 Gigabit Ethernet PCI Express
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:08:00.0

And this is the result of ifconfig -a:

It'd been working well for almost 1 year with Ubuntu 9.04...

Thanks for your help...

...I'm sorry, forget my post.

Apparently it was a network problem here in the office (the DHCP server was down). It was just bad luck that it happened when I upgraded Ubuntu....

@Xmat:it's all good. @everybody!:I posted the logs a couple of days ago and it should have some info for all you UBUNTU Superheros....thx

*EDIT* I Upgraded to Lucid 04/30/10 or last night. *Note* Ubuntu 10.04 actually found my Linksys Wireless-B Network
