I have had this iMac for a couple of years, and I have had constant issues with the wifi periodically disconnecting (only recently cared because I have actually started using it). I have recently upgraded to OS X Mountain Lion and that hasn't seemed to solve the issue. My Linux and Windows Machines that are right next to the iMac have never had any issues with wifi dropping out. What could be the problem here? I honestly do not like macs so I have never spent any time on them and therefore don't know much about how they work, so please keep that in mind when answering.
I have attempted to search it, and it does seem to be quite allot of issues with this, but no answers (at least not in the first 20 pages of most forums).
