Hey Guys, really need someones advice. Here is my problem. I have a Wusb300N and my computer is running Windows Vista Ultimate. My problem is that the adapter will loose connection all of the sudden and will not connect any more unless I restart the computer. This doesnt happen under windows XP. I am using linksys latest WinVista Drivers. The other thing is that My keyboard and mouse are Bluetooth and I dont know if that affects the device. One notisable difference between xp and WinVista is that under vista the power led on the Wusb300n does not come on, only the link led. Under XP both leds come on. I also have a PCI card WMP54g 4.1 but removed it since it produced blue screens under vista so I purchased the WUSB300N believing it would have better support. I do have 2 routers, currently using a WRT54G but also have a WRT300N and got same ressults. Problem is most when doing many downloads. Looks like adapter is flodded or something. Any suggestions?
