I had this with my BT Home Hub
I fixed it by carrying out in this order:
Factory reset the now TV box - leave it to reset, leave it on and plugged in with TV on.
Go to your BT HomeHub and router - turn them both off at the mains, wait 30 seconds
Turn the power back on to the router and the modem
When all the lights are blue on the router (Power, Wireless and Braodband) go back to the Now TV box.
Use the secret wifi screen easter egg ( press home X5 then quicky press FF, Play, Rewind, Play FF, just once each)
When the secret wifi screen is dsiplayed make sure it says Network Ping Disabled.
Go back and then start the configuration process to connect ot wifi, and then log into your Now TV account.
you are a god!!!!!!
1.5hrs i spent on the phone to Virgin Media with 3 difference tech people today. Then did this and i'm sorted.
the last techy found you post, but didn't tell me to press in quick succession so got no where. Looked up you post myself before it got sorted.
Thanks for saving me more hours on the phone trying to get it sorted.
I've read through various posts intros and have a slightly different issue. My box was connected and working fine but I mistakenly switched off my router last night. Since turning it back on all other devices are connected except for the now tv box. It can see the router and the password is definitely correct but won't connect. Any thoughts?
Your issue could be an IP address conflict. You could try turning off all devices that connect to the router (including wifi enabled devices), turn off the router, wait a few mins (make a brew), switch it back on, wait a few mins, switch the Now TV box on and then the rest of the devices. This should force the router to allocate an IP address for the box first.
