WLAN device driver loading Issue

Hi,

I currently own a Compaq Presario V6000 and have had it for roughly just over a year now. Lately the WLAN device is having issues. Sometime when I start up the Laptop the WLAN driver does not load up. I check the device manager and the "broadcom 802.11a/b/g WLAN" device comes and goes and does not register sometimes. I also check the HP wireless assistant for "Installed Wireless Devices" and the WLAN device is not detected only the bluetooth device is.
Can you please assist me with fixing this problem? I hope I have provided enough information to understand my problem, If any more information is needed I am more then happy to assist.

Thank You
George.
