Hi, I have a macbook 7.1, Ive bought it in mid 2010. And recently it keeps disconnecting from the internet, and I cant reconnect. Ive tried almost anything, and the only way to reconnect is to turn my mac off entirely, and then turn it back on. Only to be able to have an internetconnection for 10-20 minutes. Then it disconnects again, and I have to restart my mac once again. Its extremely annoying to restart the entire time, and this makes it basically impossible to do some other tasks which require a stable connection for a longer period of time.
