We have been using powerline adapters to get internet connections in various rooms around the house. Just recently, we struggle to get an internet connection for the TVs in the rooms furthest from the router, even though the powerline adapters all appear to work.
I want to call someone out to help with a better solution to transmit internet round the house. The trouble is, I don't really know who to call out. What kind of professional could I call to help with this problem?
Thanks in advance.
