Hello,I recently bought a new house I have got my HUB 4 and self set up kit installed it downstairs in wall socket 1 and I was getting 500mbps, then upstairs In what will be out office room I see another virgin media wall socket, we shall call this (wall socket 2) so I assumed this one may be for multi room, but I would rather have the HUB in the officer room so I can have all our office devices wired. So I plugged the HUB in upstairs in wall socket 2 and it was all connected and working but was only getting up to 50mbps, so I was thinking maybe them cables to wall socket 2 can’t transmit 500mbps so I took my hub down to the original wall socket 1 and I’m only getting up to 50mbps downstairs now too? I should be able to just have it plugged in the upstairs one and still get 500mbps surely? Im paying for 500mbps but now I can’t get above 50 in any? I was only getting 500mbps on day one of install, any help would be wonderful
