Hi. Bit of a dilemma as I am getting conflicting things told and I need clarification. In future (I already have a zgemma) but in future i'll be buying at least another 2 zgemma's (one for my sister and one for my dad) now my sister I won't have a issue with as she has fibre optic in her room so it will be a easy case of connecting her box via ethernet cable she's sorted. My dad though it's a different matter. Now his box will be downstairs and nowhere near any routers. I been advised the best option for me is to get a powerline adapter but I not convinced as how that could work? I do have some understanding that one of the adaptors has to go to into the fibre optic modem via the ethernet but how would I get the 2 power adapters to talk to 1 another? (Hope somebody understands what I mean)
