We have a pair of booster plugs, supplied by VM, to enable us to use the TIVO box in a different room to the router without using the ethernet cable. This works fine.
The WiFi connection in my office (attached, integrated, converted garage) is patchy. Can you add a 3rd booster plug to the existing ones in order to improve the situation? If so, does this require a completely new set of plugs or can you buy/be sent another one to add to what we already have?
FYI, I did have a separate set of 'TP' plugs that were supplied by my employer, but these seemed to 'conflict' with the VM ones & didn't have any (positive) impact so I have removed them.
