I'm a WUSB54G version 4.0 user and connected to WRT54G as my router. It works fine if I do not shut down my PC. However, everytime I switch on my PC again, the Power LED on the wusb54g ver4.0 doesn't on at all. I need to unplug/plug more than 100 times in order for the Windows XP to detect it as a valid wireless network adaptor again. The problem doesn't occur if i restart my pc. Is there anyone here having the same problem I faced? Is my driver problem (I've downloaded the latest driver from linksysinfo.org) but it still the same issue, or my mobo having issues (I can use the same usb port for my portable hdd/mouse)? any tweak needs to be done? If you have the solution, I really need your help. Thanks.
