SPEEDTEST WOW TV
I have a second router and a TV Cable box connected using the same coaxial cable, but I have unplugged them to do a test, with the same results. I live a couple miles from town, and I have tried with a Samsung Galaxy over wifi, which seems to get some faster speeds (into the 200mbps range) which seems acceptable because it is over WiFi, but still isnt close to the 500mbps I am supposed to get. What other devices are connected to the same coaxial cable that is connected to your cable modem/router/gateway device (splitters, cable boxes, etc)? How far from town do you live? Have you measured performance with any other device than your aforementioned PC? Any change in performance using alternate cables/router ports? Kinda impossible to label just one until you personally can rule them out.
SPEEDTEST WOW PC
There's half a hundred different possibilities, sorry, and may not have anything to do with your pc or the router, or they might.

The wiring itself might be suspect, even a single kink in the service wire will have bleed to ground, where certain bandwidths are basically nullified. Splitters alone can cause massive drops if there's more than one, and it should be a decent splitter, not the uber cheap variety. You could also be suffering interference, RF mainly, from a bad ground in any equipment, including splitters and/or amplifiers on the house. Windows has had some major upgrades, which have affected audio, graphics, USB and Lan drivers, so if you have older chipset drivers, they could be in conflict, check your motherboard support site for updates. There's also local traffic that'll change possible bandwidth, a test run when everyone in the neighborhood is online will show slower results than in the dead of night when ppl are asleep. Also there are sometimes bad connections on bumps, you'd have to run a ping test to see if your routing is actually good and not suffering lag at other junctions. The further you are from a node, the slower your connection. A lot depends on the hardware between your router and the isp.
