Just moved into a new property and my old homeplugs; Solwise AV500 passthroughs drop the connection to my PC every 2-3 hours at random. The connection isn't dropping at the router, all other wireless devices work fine and I know the homeplugs are ok because they worked fine at my old property so I can assume the wireing is at fault? Is there anything I can do or do I need a rewire to solve?
