I've recently had my IPad 2 repaired, front screen and back. However now the wifi signal is really strange, I have to be literally sat on the router and its really slow?? Both at my mums and sisters it was fine before the repair and on ios 5.
The repairers failed to send the Sim card slot back so it hasn't got its own network, or that part of the casinng covered, would this effect signal on wifi??
Any help would be appreciated
