I am using a Linksys WUSB54GC. I have tried both an older RALINK Vista driver and the driver available from Windows Update. I am running Windows 7 x64. What generally is happening, is randomly while I am logged on, the wireless connection will either become limited or will totally disconnect. If it totally disconnects, I cannot do anything but do a hard restart to remedy the problem. When I attempt to fix the problem by pulling it out and putting it back in, or uninstalling it in device manager, or disabling it in device manager, device manager hangs. I try using the troubleshooting wizard and try to create a new connection to no avail, once it hits this stage it will not connect to anything.Just to add, I am using WPA2 encryption on my wireless network.
