I have just removed the installed version and reinstalled this version 220.127.116.11.
I'm using WinXP SP3 on the ASUS notebook N61J.
There are 2 versions on the Intel Download center. and I have used both of these with the same results - auto connecting - disconnecting - reconnecting. And, the speeds are always either 130 or 144 Mb/s, not 300 Mb/.
--Wireless_15.2.0_Dx32.exe 11,767 KB
--Wireless_15.2.0_X32.exe 38,142 KB
There is no support from ASUS; I just wanted a 300MHz Wireless & Intel's always performed well.
The Bluetooth has been equally troublesome with the Nokia 6350, when it connect reports "Only audio files will be transferred" followed by "disconnected" about 20 seconds later.
Maybe this device was designed for Windows 7, which my clients and I will moving to in a few months. Maybe I should have purchased a different model such as the N6235, but I'm not sure there are WinXP drivers.
