intel wireless suddenly stop working

It just dissapeared one day. It’s like I deleted the driver for my ipw2100 card. I tried to reinstall it, but it didn’t helped (so, it’s installed , from the beginning). Is there someone with similar problem? Help. Thanks.

I think there is a wireless package for that intel unit
check you have it

is this 11.2 ?

Does the wifi unit show up when you run the command below?

/sbin/lspci -nnk
