Every time I download a new app or updates for existing apps after a few seconds my modem/router will stop sending any data to any device connected to it. So I have to go disconnect my router and modem to regain connection. It only started a few days ago and since I don't have a data plan at the moment it's becoming a real pain. Any ideas why it's doing this? Anything I can do about it? Using an iPhone 4S by the way.
