Wireless Networking: Using a Cisco/Linksys WUSB54GC on Gentoo

November 13th, 2011 1 comment

We live in an old house, which has the unfortunate side-effect of lacking a wired network of any kind. All of our machines connect to a wireless network, and my desktop is no exception. I’ve got an old WUSB54GC wireless stick that was manufactured some time in 2007. In computer years, this is way old hardware. But with a bit of work, I managed to get it working with my Gentoo install.

This bitch is old... but it works

I started out by installing the NetworkManager applet with a tutorial on the Gentoo Wiki. This was a straightforward process, and after a restart, the applet icon appeared in the top right corner of my screen. If you left-click on the icon, it drops down a menu that lists your wireless interfaces. Under the Wireless Networks heading, it said that it was missing the firmware necessary to talk to my hardware.

The next step was to look around the net and figure out the firmware/kernel module combination that supports this stick. I found my answer over at the SerialMonkey project, which is run by a group that took on maintenance of older Ralink firmware after the company of the same name dropped support. According to the SerialMonkey hardware guide, my stick (or at least a very similar stick called the WUSB54GR) works with the rt73usb kernel module and related firmware.

This known, there are two methods of proceeding. Those running older kernels may need to manually compile the necessary packages using instructions similar to these, from the Arch Linux project. For more modern kernels, the Gentoo project provides a Wiki entry detailing the necessary steps.

After following the steps in the Gentoo Wiki entry, I restarted my system, and now have full wireless support. Genius!

Ubuntu 11.10′s WiFi crashes my router

October 19th, 2011 9 comments

No seriously, it does. Whenever it makes a connection to the router it causes it to enter some bad state wherein it refuses to allow any connections to occur. This also has the effect of booting all other machines from the network. Apparently I’m not the only one to have this problem either.

I did manage to find a bit of a work around though:

  1. Set your wireless router to Mixed B/G mode only (yes I know, you lose out on N by doing this…)
  2. Enter the following into a terminal:
    echo "options iwlagn 11n_disable=1" | tee /etc/modprobe.d/iwlagn.confg
    sudo modprobe -rf iwlagn
    sudo modprobe -v iwlagn
    sudo service network-manager restart
  3. Maybe reboot?

I’ve also heard of some people getting it to work by enabling this instead of disabling it. To do so simply change the 11n_disable=1 line above to 11n_disable=0.

Hopefully they will have this annoying bug fixed soon.




I am currently running a variety of distributions, primarily Linux Mint 17.
Previously I was running KDE 4.3.3 on top of Fedora 11 (for the first experiment) and KDE 4.6.5 on top of Gentoo (for the second experiment).
