Linksys WPC54GS-UK wireless card with Ubuntu Edgy

I dug up my ancient Toshiba Portege 3480CT laptop, and installed Ubuntu Edgy 6.10 on it by connecting the hard to my desktop PC (as the laptop doesn’t have a CD or DVD drive). Then I found that the wireless card I had, a Cisco Aironet 350, doesn’t support WPA. After trying and failing to get a Belkin card to work at all, I tried the Linksys WPC54GS-UK. With some help from the instructions on the Ubuntu wiki, which I’ve summarised in a new wiki page, the card works perfectly and I now have web access all around the house instead of having to go and sit in the study.
