Edit -> Solved as Router.


Could use some help here.

I have a D-Link DWA 552 XtremeN Desktop adapter.
A Linksys/Cisco WRT610N Router.

Connected to Shaws 50Mbps plan.

Yesterday, for whatever reason, speeds dropped off from the 40-48 Mbps range down to the 5Mbps to 7Mbps range as reported by speedtest.net.

My ping, if it helps, remained excellent at 20ms.

So reboot the router and modem, and it gets a little better(18Mbps) for about 4-5 minutes, then back to 5-7 range.

Upload speed through out the testing is pretty much bang on 2.12 to 2.13 through out the duration.

Oddly enough when accessing the Router, the menu switching is slow. Like waiting for a webpage to load on mid 90s Dial-up, sometimes not fully loading at all.

So next step -- > Rewire basement. (Oddly enough, having a 4 year old girl beaking off for 5 minutes about how ugly all the cables strung around HER tv area and how they'd be better under the carpet, is to say the least, somewhat rage inducing, followed by said 4 year old's mother asking if I could either put it under the carpet or around the couch....)

Plug the modem directly into the tower and it gets normal speeds as usual. (Oddly enough, slower upload speeds)

So I am guessing there is an issue, either the router or the wireless card.

The problem is, from my books it could be either one, but I am not sure of a somewhat sure-fire way to to diagnose this.
