Yesterday I unlocked my phone (all legit via Orange) but now every time my phone locks and I then unlock it the wifi has disconnected and I have to go into settings > wifi> and re-enter the password. Every time!! Please can someone advise?!
Wild guess is that during unlock process you restored and updated your phone and new ios does not like the unoriginal network names. Just rename it in something original. Like "Netgear" to "my own network"
Is this a new problem, or has it always been there? Is your router's network name (SSID) still the default? If it is that is likely the problem. You can also try Settings/General/Reset - Reset network settings.
