No wireless after trying to patch driver

Asked by hogm

After trying to patch the wireless driver to be able to use it for wireless security analysis and testing Ubuntu 7.10 no longer sees my wireless card. It is an Intel Pro 2200. I would like to re install the original wireless driver that was working fine before but i can not find anywhere instructions on how to do it. Guess the only other option is to do a complete reinstall but i have lots of software and it would be a pain to re do it all over. Can somebody help???

Which steps did you take to patch it? Make sure the 'ipw2200' module is loaded, and not any other module.

I followed the instructions here: http://ubuntuforums.org/showthread.php?t=501148 but when compiling ieee80211 i get the following errors:

make[2]: *** [/home/hugo/patch/ieee80211-1.2.17/ieee80211_tx.o] Error 1
make[1]: *** [_module_/home/hugo/patch/ieee80211-1.2.17] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.22-14-generic'
make: *** [modules] Error 2

The compilations stops and i ended up without wireless.

Ah, apparently those directions have you use the "remove-old" script which I *assume* deletes your existing drivers. Not very smart to do before the compile, if you ask me. I would try reinstalling like so:
'apt-get install --reinstall linux-image-`uname -r`'. Make sure you use the backticks around uname -r to get your current version.

Can you help with this problem?
