If this problem only occurs on a particular network, say your home network, you could be having problems with your wireless router (check for router firmware update, power off and restart router) or you could have interference with other nearby networks (change router channel, etc.). Your problem could also be unrelated to your equipment and be due to difficulties in your ISP network. You could check with their support people.
If this problem occurs on all networks then you may have a problem with your iphone hardware.
