Hi, I'm desperately hoping you can help me....
I just reinstalled windows xp professional service pack 2 on my HCL laptop and having installed the necessary drivers everything seems to be working except for my WLAN. I am able to connect to the internet using a cable, but I can't seem to turn on the wireless. (when i press the hardware button to turn it on nothing happens).
Looking into device manager I found a yellow question mark against Ethernet Controller and it says the drives for this device are not installed (code 28).
Unknown Device Identifier shows it as
Ethernet Controller (unknown device)
chip:Atheros Communications AR5007 802.11a/b/g Wireless Network Adapter
the only other unknown device showing up on Unknown Device Identifier is
Video Controller (VGA Compatible)
Chip: ATI Technologies Radeon Xpress 200M (RS410)
My laptop is an HCL Notebook K21 PDC.
Can you please advise me on how I might solve this issues.
