Same here;
Hi guys, i have a very big problem regarding iPhone's wi-fi and bluetooth connectivity,
whenever i try to connect any password protected wi-fi iPhone says 'incorrect password' soon after i realize that even bluetooth doesnt accept any device which are password protected and i recieve same error, im not sure but i think it happened after 5.1.1 update, i tried everything but nothing happened, things i tried are below;
- tried different routers/modems
- tried different iPhones (which are connected but mine NO)
- reset Network via iPhone
- hard reset
- tried different kinds (WEP, WPA etc) and combinations of password
- tried different channels (12-13-11-9-Auto etc)
None of them above solved my problem now im trying restore, it will take sometime i guess (internet speed is low)
im using iPhone 4s
ios 5.1.1
If you know anything let me know, help me Please.
Kind Regards.
