Big Problem: Connections Tray "Not Responding" => No Internet + Slow P

Hi !

Whenever I connect to the internet via my own WiFi router at home, the connection will terminate after 3-7 minutes and the wireless network will turn off automatic.

If I place the cursor on the wireless icon in the lower right hand tray, the following happens:
I get no response. If I right click on the icon, nothing happens. If I go to Start, Connect to, and wireless connections, nothing happens. The only way I can restore a functioning connection is to shut down the machine. However, when I try to shut down the machine, a windows box opens indicating an attempt to end the connections tray. If I click end program, the box shuts and shut down proceeds.

I bought this laptop last week during my trip to China (So I can't return it for warrenty and I'm sure it's software related...)
It's a HP Pavilion DV2000 / Compaq V3500 with built in Intel Pro Wireless 3945ABG Network Connection.

I have Windows XP Service Pack 3 installed with the latest new updates.
I already have done a virus and spyware scan, totally clean.
I have already updated my drivers to the latest version with DriverMax.
I have already tried running WinSock to repair damaged sock files.

I have seen the problem mentioned in other forums, I already googled and tried all given solutions on google, without luck. I'm desperate for help, please help me

Thanks in advance, I really need help fixing my brand new laptop
