Hello, about 6 months ago I put together a nice gaming system, however I did not have the money then to add any wireless cards (and obviously it is for gaming so i don't want to do that), however I have my computer set up in a room with no coaxial connections, and it is very far away from my router (which cannot be moved), so over the last 6 months I have had an apple airport express plunged in via Ethernet to my sabertooth Z77 mobo, and then the airport express connected to my 5GHz wifi network. I was wonderimg weather getting a power line adapter would give me a signification or noticeable network performance boost. (oh and my router is an apple time casual 3rd gen)? thank you
