For no reason that I know of today my touch has dropped its wifi connection - it's been working perfectly since day 1 - I don't understand it keeps asking for password again saying it's incorrect when I know it not?? If I go into settings and switch wifi off, then on again - it sees the network, the tick shows up and if it connects then abotu 2 seconds later the tick dissapears again?? Any ideas anyone please??? Other wireless stuff in the house is working fine, I've not put any new software on it the last few days. It was plugged into its dock the other morning when we had a powercut but its been fine since until today????
