I live on a campus so there is no way to get a closer router, and there is no way to do a wired connection. I am currently using a Netgear A6100 usb (AC600) in my new pc build. The internet is extremely inconsistent, and I frequently time out. The wifi card on my macbook pro is far more consistent. Will I see significant improvement in performance (consistency) if I buy a rosewill n900pce?
It's less about the distance between you and the router and probably more about obstacles. I used to game only on WiFi and then my wife and I moved into a new house. My office is only about 15ft from the router but there is a 100yr old wall and a fridge between my antennas and the router so WiFi gaming comes with huge packet loss sometimes.
ALSO, I find that wireless gaming on anything less than a 5 Ghz band is not as reliable. So if you have a 5 Ghz net available make sure you are using that. "
I just noticed you are on a campus router too. At peak hours your connection will vary due to everyone being in the dorms at the same time. I tried playing a game on campus once and at the top of the hour when classes got out the connection would plummet. We're talking the difference of a 32ms delay to 400ms.
