Low power user here. Just upgraded from DSL to Comcast cable a few months ago. Turned in the Comcast gateway a week ago in favor of a Motorola SB6141 modem, and of course my trusty Dir-655 (Hardware A4, Firmware 1.31 NA). The default settings haven't been touched.
I have pretty basic internet service...."as high as 25 mbps." Hard wired directly to the modem, I am getting around 29mbps; hard wired to the router, 25 mbps. Immediately testing wireless 6 inches from the router, speed is 4.5 mbps. (speedtest.net) That's consistent with both laptops and one tablet in the house, regardless of location. Two Windows 8 and one Windows 7. We have a couple of DVRs wirelessly connected, though it's pretty rare that we stream programming in. We are in a single family house, but see eight networks nearby, two with two bars, and the rest with one; our immediate neighbor is a heavy gamer. It is rare that more than two wireless devices are in use in our house. We would enjoy streaming Youtube and occasional movie with out interruption. Sounds like the DIR-655 should be able to do it.
I have read lots of earlier discussions on this board, but they are a little above my head. I know how to access the router on line, but that's about it. Anyone have the patience to help me out? Thanks!
