I have a MBP running Mountain Lion 10.8.2 connected to Mediacom using their standard Netgear modem and it constantly loses wifi signal. Every other device stays connected at all times so I know it's just the computer. It started awhile back and has gotten to the point where I can't seem to do anything without having to turn the wifi off and reconnect. This sometimes solves the problem I usually have to do that 2-3 times before it works. Sometimes it may last 20-30 min but some rare occasions it will only load one webpage for a min or two. This is getting very annoying and has made any video streaming a no go. I've ran diagnostics done everything I could its all good... a ghost problem for me.. Any help?
