Sudden problems with internet connection
I just bought a brand-new macbook this summer, to replace my old computer which pretty much died. I've had no problems with it, but all of a sudden my internet connection keeps dropping out. It's gotten to the point where I cannot download or upload anything, or use programs like Skype or AIM because my connection keeps going in and out.
I honestly have no idea if the problem is with my computer or not. I'm in Paris for the year, and am staying in a hostel-like public housing situation. The problem could be with the wireless here, although since it's just public wireless I wouldn't know. It was working fine until two days ago.
If the problem did happen to be with my computer, is there anything I could do to stop the connection from dropping in and out?
MacBook, Mac OS X (10.5.7)
