I have successfully JB my ATV2 (after a few attempts) and have the ‘computers’ and ‘settings’ (with FC logo) on the screen, but cannot connect to any wifi networks. Everything else in the home is connected to wifi ok.
If resetting, or restarting ATV from the settings menu, all I get is a black screen (with the solid light on the ATV).
I then have to re JB it to at least get it back to the above scenario.
Has anyone else had this issue ? Any help or suggestions appreciated.
