Hi guys, want to thank everyone for their advice, I have tried using different cables, but to no avail, so I will take the plunge and buy the booster. How my set up is, I have a brown box, with a splitter, then a white box in my living room for the internet, and a white box in my bedroom for the TV. I opened the white box in my bedroom, and it has a single splitter, so one wire goes in and one comes out. My question is will this splitter still work, I'll have a spare port on it... Will I just need to cover that up...
