Apologies if a stupid question. Completely ignorant with this stuff. We’re converting our garage into an office space. Unfortunately the home wifi doesn’t reach out there. Could I just get some of the wifi discs that BT sell on the store and expect results or is it more complex than that?
The best way is to run an Ethernet cable from a home hub port, to the garage. Then add a wireless access point to the garage end.
The other option would be to use a pair of powerline adapters which have wireless built in, that would save running a cable.
The BT disks are unlikely to help with your problem.
