I just bought the Levelone WUA-0616 N_Max 300Mbps Wireless USB adaptor. The thing is..when I insert it in my USB port..there is no blue light on at the adaptor. and when I try to install it with the provide driver, it said that there is some error with the file. I try the adapter at my laptop, and it works. no need to install the driver. my pc is using windows xp with pentium 4.please help
