My cheap 150n D-Link DIR 601 router is at least 4 years old and has suddenly gotten to the point where it delivers only 19% of the download speed delivered by the Arris modem (90-95Mbps). My ISP is Comcast/Xfinity so I'm thinking about swapping the modem for a Gateway combination modem/router (Comcast allows you to do that free and it does not increase your charges). However, I'd like to know from anyone who has one how satisfied you are with the router side of that modem. I.e., what % of the "hard-wired" speed do you get with wireless connections?
