Ubuntu hangs when configuring Gigabyte wireless card GN-WP01GS

[Marcin Gałązka]

Configuring network card via network-admin results in system hang on Ubuntu Dapper.

Step to reproduce:

1. Run network-admin
2. Choose GN-WP01GS wireless card
3. Click Properties
4. Enter settings (essid, wep-key, dhpc etc.)
5. Click Ok

System hangs after clicking Ok.

After booting iwconfig process takes ~100% CPU - killing or renicing process for some reason wasn't possible. To fix it wireless card must be removed from PC, then related entries deleted from /etc/network/interfaces after booting.

Workaround and more info is present here http://ubuntuforums.org/showthread.php?t=132980&highlight=ralink (I think this is solution for any RT2561 based card). Basically (for Dapper) it involves downloading firmware, config file, fetching config file with proper data (essid, wep-key...) and than enabling network interface using ifconfig or dhclient. Sometimes additional steps must be performed like adding default gateway using route.

Mentioned above workaround isn't 100% stable either. System still will hang if:
- config data isn't valid (e.g incorrect wep-key)
- access point settings are changed

There is also a (random) chance that system will hang when running ifconfig/dhclient (with proper data) or few second after that.

Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?

Partially - first attempt to configure this card on Feisty results in a hard lockup. After that everything looks ok, although it involves CLI - both network-admin and Network Manager were unable to do their work.

I suppose that Feisty uses a driver from http://rt2x00.serialmonkey.com instead an old Ralink driver so most bugs should be ironed. Not all nevertheless - https://bugs.launchpad.net/ubuntu/+bug/122774 ;-)

Same for dapper, please.
