I am running 10.10 on a IBM X31 with excellent results. I use the madwifi drivers with the internal Atheros wifi card in the X31.

I am pretty religious about letting the software updater go through and update everything. About every 3rd or 4th time or so, the madwifi drivers are either lost or overwritten -- I basically lose the connection to the Atheros card. It happens enough that I have generated a script to reload them.

Any idea what package updates might be overwriting them, and is there anything I can do to tell the updater to leave them alone?
