Thanks for the reply.
Might have to....but first I'm check 'online', as per SidBarker's reply.
BTW, I did think of just extending the ethernet.
Only problem is the original room will have a guest staying there, which means I'll have to leave the modem powered on 24x7, as I won't really have access to the room.
Not a
big problem I suppose.
But if I can extend the coax, and can relocate the modem, meaing I can switch it off every evening, along with the other PC stuff
