WRT54G

But note that all of our other devices "work" using this router. Even this wireless card on this computer when using windows.

In the grand scheme of things I might need to just get a different wireless card.

seems you are not the only one with this kind of problem.
I also suggest you experimentally turn off wireless N at the router. it won't affect the other units ( a bit of slowdown)
you could try the backport drivers (they used to work ok before all the updates)
If the problem persists, let's install a backported driver. Please get a temporary wired ethernet connection. Download this file to your desktop: http://www.kernel.org/pub/linux/kernel/ ... -1.tar.bz2

Right-click it and select 'Extract Here.' Now open a terminal and do:

Code: Select all

sudo apt-get install build-essential linux-headers-generic

Code: Select all

cd ~/Desktop/backports-3.13-rc2-1

Code: Select all

make defconfig-wifi

Code: Select all

make

Code: Select all

sudo make install
'make' takes a few minutes; please be patient. Reboot and let us have your report.

I don't think my router has "N" as an option. It's an early/old linksys wrt54g that only offers B and G.

I saw some errors while installing. I've rebooted. How do I use this temporary wired connection?

do you actually have a wired ethernet connection on this PC?
Also make sure your router has the last firmware.
I really don't know what to try else...
