Ok, so I've had my laptop for several years (I wanna say 4, but possibly more), it's a Toshiba Satellite. I'm running Linux mint 15, and am having a strange new issue, after several hours of running my wireless stops. It can SEE wireless networks, but refuses to connect to any of them. (On a sidenote, connecting to a router with a cable at this point works fine)
The fact that it can SEE the networks make me think the card is in good condition, and it's software related
The fact that it works for several hours before booting me makes me think perhaps the transmitter is getting too hot.
I don't use my laptop in dusty environments, and keep it on an elevated surface (alternatively, I actively try not to let it sit on soft surfaces where the vents get covered). I spray out the cpu fan about once a year with compressed air about once a year, so I really don't think the insides should be too dirty.
Finally, unfortunately, sensors only gives me CPU temps, but they run about 40-50 degrees C, which from my understanding is perfectly normal for an I3.
Does anyone have any suggestions on what I can do to determine the root cause of this?
