My macbook recently started dropping its wifi connection randomly. Sometimes I stay on the network for a few hours, sometimes a few seconds... What could have made it suddenly start doing it? My landlord got a new router for my building (student accommodation), its a Belkin and is secured with WEP encryption (lol) whereas we used to have a netgear router where he had to register your mac address to get on. Could the new router/wep encryption be the cause? The thing thats confusing me is that often I need to restart my computer to connect to the network and often selecting the airport menu makes the computer beachball... Could it be a hardware/software problem on my end?
