I returned to college last weekend and found that now that I am connected to my schools wifi, the game crashes after about 1 minute of being in game logged onto a character. Is there anyway to fix this or am I doomed?
You'll have to speak with you school's IT department. Sony can't help with that, unless you have the same problem with other connection sources.
Graye's right. You may want to try checking to see if they are able to handle gaming connections. You may also want to check to make sure the connection is successfully going through to the Vanguard servers.
