My white Macbook keeps dropping the wifi signal strength. The internet connect shows a variation anywhere between 2/3 bars upto the full 15 depending upon how long the laptop has been switched on and running. I have SMC fan control downloaded and the present temp as shown at the top of the screen now is 47C 5354rpm. Is this a normal operating temp or not ? Just normal use, email , safari etc no graphics or heavy word processing.
I am trying to eliminate possible causes of the varying signal level strength to pinpoint the problem.
Thanks

47 seems ok, heat shouldn't affect the wifi either way.

One thing to point out, if you're browsing and hit a flash site, eg; diablo 3 website, then it could cause the machine to warm up as it'll max out the CPU. So if you hit a flash site and switch to another app, there will still be some draw from Safari, so that could warm things up.

The temp might cause a problem with wi-fi, if it's a dodgy connection on the board, wasn't there some issue with things heating up and due to thermal expansion something would stop working? Could be same type of thing here.
