Wirelessly posted (Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3) One of my friends got a 4s last week, but she has problems with the WIFI. Every time she wants to make a FaceTime call it freezes within ten seconds and her WIFI breaks down. She has Internet TV for instance which breaks down when FaceTime freezes. There have been NO problems with iPad. Any suggestions?
