I have the 7100 build of W7, and a Belkin USB N wireless dongle. It works fine, except that whenever I switch the computer on or it comes out of sleep, it doesn't recognise that it's plugged in and I have to take it out and put it in again, which is kind of annoying. I have a USB keyboard and that doesn't have this problem. Any suggestions?

Which driver did you install for this?

The Vista 64 bit one that came with it I seem to remember...

From a disk or from a website?

from the disk supplied with it.

First can you try downloading the latest driver from Belkin, failing that, uninstall all instances in device manager and see if Windows installs a fresh one for you.
