Not obtaining IP address / timed out

[Jmc781]

After the connection dropping a couple of weeks ago, and a message on a device around ipv 4 vs ipv6, I'm be managed to get tv/ PlayStation etc back connected, using a booster that is wired by Ethernet cable.  The only device I'm struggling with is the q box- in set up/ re activate it can't obtain ip address and is timing out- even though the signal strength in the room is really high.
