With the release of Ubuntu Gutsy, there remains questions as to whether or not Ubuntu wireless bugs with once working chipsets have been resolved. In today’s post, we look at what works, what will never work reliably and what you can do to have wireless access with 802.11g using WPA - no excuses.

Items of note:

• Uninstall network-manager. You can do this by going to System, Administration then choosing Synaptic, then doing a search for network-manager-gnome, removing all of it from there. Or easier yet, Applications, Accessories, terminal, then using your mouse to paste in this code.

sudo apt-get remove network-manager-gnome network-manager

• Now go to Wicd’s download page, install the ‘testing release’ (wicd 1.3.4).
• Making sure that this automatically starts up for you at each boot, goto System, Preferences, Sessions. Click ‘new’, then add a title and in the ‘command’ box, paste this.

/opt/Wicd/tray.py

As for how Gutsy sees wireless cards, generally it will be something like wlan0 or wlan1, etc. Use the screen shots below to help you get that setup. I recommend this MIMO card hands down. It is based on the Ralink chipset, RT61, while using another RT based driver. Another card that works is this one based on RT2500. And of course, this card based on the Prism chipset, which is not working in Gutsy.

Using your console and the simple iwconfig command to find out what your card is called in Ubuntu.
