I have an old (IBM) Thinkpad T42. It was pretty much useless running XP, so I decided to install linux. I first tried Puppy Linux, but eventually settled on Lubuntu. I couldn't run 12.10 because it requires PAE, which is not available on the Pentium M. I am now running only Lubuntu 12.04 (I didn't partition it or anything; I don't have XP anymore).
Everything is working fine, except for the wireless internet — which is a pretty big problem for me. Under XP, the internet worked. It still worked under Puppy... but now it's not working. The thinkpad sees my network, but is unable to connect.
This post: Wireless doesn't work with Windows 7 and Lubuntu 12.04 is similar, but doesn't help.
lshw -C network tells me that I have a "Cisco Aironet Wireless 802.11b" interface, and
rfkill list all returns nothing...
On the network side: I have an dual band Apple Airport Extreme. Most of my [new] devices use the 5GHz signal, but the thinkpad is obviously seeing the 2.4GHz one.
Any help is appreciated — I would really like to get internet up on this computer.
