I'm away from home, and am using a different WiFi network, of course. The problem is that whenever I use the internet, it works for a few minutes before the spinning wheel appears. After is appears, the mac becomes frozen and I have to hold the button down to power off and restart. I've done this about 10-15 times tonight. However, the only thing I can think of that has been making my mac act differently is the WiFi network I'm on. I currently am not on this network, and am using my phone's WiFi hotspot; I have run into no problems yet, and my mac appears to be working normally again. So my question: is it possible for a network to affect a mac like this? It just seems really weird that it has been acting up so much and is suddenly fine again once I am no longer using the network. Thanks.
