Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have been reading various other posts on the matter but none of the solutions are working so I thought I might as well ask.

Just installed Ubuntu Server 11.04 on my old Dell Optiplex 330. It has a wireless PCI card installed that I bought for it's compatibility with Ubuntu 10. It was working on Ubuntu 10 prior to the new install.

After the install there were no lights on the card and I can not use it.

When running; sudo lshw -C network

the device is listed but labelled Disabled.

The card is a Ralink corp, RT2561/RT61 802.11g PCI

This is a headless install so command line help only please.

Thanks in advance!

sudo lshw -C network

What is the output from: sudo lshw -C network and iwconfig? I am using that WiFi chipset, but in an external device. –  david6 Dec 2 '11 at 21:23

The Ralink Technology cards, and specifically RT2561/RT61, have compatibility issues with later drivers (developed for later cards).

see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/665364/

Your best bet is to try blacklisting the later drivers, which will stop them trying to control the card (and failing). The only other alternative is to compile your own driver.
