Ok so here's the thing. I've just moved house and sky told me my internet would be active the 28th of this month, fine I'll make do without. So i've moved into my place and I plug my stuff in. Here's my setup. Skybroadband router wired into - Sony Bravia TV, Playstation 4, Desktop PC, Sky HD box Connected Wirelessly - PC laptop, Iphone, Ipad So on friday morning right before they disconnected me everything worked perfectly. 3 days later i've moved into my new house, Plugged everything in, I know my internet isn't going to be working for another 2 weeks but thats fine. Until I notice that my internet IS working WOOHOO sky must have connected me earlier than they had said. However, here's the problem, only the wireless stuff works, everything that uses an Ethernet cable doesn't which is strange, so I test out the WiFi connections on the TV, PS4 desktop pc, and the internet works fine. I can't really get my head around why the router would stop letting me use ethernet cables? Any ideas?
