OK, when I am logged in, I get almost always 300 speeds, but, it has kicked me 4 times in the last 10 minutes, to the point where I have had to unplug and replug back into the same usb port. I am using a powered hub, I don't know if that makes a bit of difference or not, but when it loses connectivity, it only loses it to the internet, I can still browse my network. This has not been a problem on any of my other machines, all using XP pro. And it is not that I am simply losing internet connectivity all together, because other PCs will be able to surf just fine.
And my router firmware is 1.11 as well.
