Stuck on starting up screen

The arrows and wireless lights flashing indicate an internet connectivity issue and that the V6 box has lost the internet connection.  If connected via an ethernet cable double check that the cable is connected to both the hub and V6 and that the cable is snug and tight at both ends. Also try changing the ethernet cable.

If the V6 is connected wirelessly then check to see if any other devices are having problems connecting to the internet?

Double check that your hub is turned on. If it is turned on then disconnect it from the wall for around 30 seconds then turn it back on and wait 5 to 7 minutes for it to reset and fully boot up.

Also have you used the /check-services/ function to check for problems in your area? You can also a run a test on your equipment from there. 

If nothing is showing  you could also try the automated Service Status number  0800 561 0061.  This often gives details of more local issues down to postcode level.

Yeah still having issues. It seems the box gets data downloaded onto the box but still stuck. I used a wire from router to box. Im gonna try one more thing tomorrow. I have the hub in modem mode with a router i bought. Gonna try with the hub connected directly to wire.

I'll test it out and report back to you all.

Sorry for late reply. I tested everything suggested here. Still stuck on starting up screen with lights flashing. Might need a new box or summat. 

We have 4 boxes in total. Only this one is having connection issues for some background info.
