Wireless???? Ok so I fixed my problem with my audio! Now I have another "bump". There is no wireless. When I go to device manager it just says ethernet controller. When I try to update the driver, it says it can't be done. Does anyone know where the driver update for this is?

Check in the Device manager to see if all the devices are enable and working.
The one with a yellow ? against that device requires a driver installation.
Is the LAN device OK?
Source :Wireless Adapter
IF all the above is fine then here the which shows the on off key.

5 and 6 is the On and OFF.

Are you able to see any available wireless networks?

Make sure the wireless radio is on, the wireless switch should be located above the keyboard, it has the picture of a satellite.

Check that wireless service is running
XP: Click Start, click Run, type services.msc, then press Enter.
Scroll down to "Wireless Zero Configuration" and right click on it and select Properties. Set it to Automatic and not Disabled, and press the Start button, then click OK.
That should start the service.
7 (vista): Click Start, type services.msc, then press Enter.
Scroll down to "WLAN AutoConfig" and right click on it and select Properties. Set it to Automatic and not Disabled, and press the Start button, then click OK.
That should start the service.

check your wireless adapter is on... the switch is on the front of your laptop and you should show a blue light when it's on, also go into device manager and see network adapters.. you should have 2 (the wire one built-in and your wireless network adapter.. if you only have one network adapter, check the front and see if the light indicating the status of your wireless network adapter is amber.. (if it's showing amber and you're sure it's in the on position you may have a motherboard problem and you may need to send the system back (I just had one of those with a compaq computer and since the item was within warranty the fixed in a week)

if your wireless adapter light is blue and you see your wireless adapter in device manager follow this instructions and you should be ok,

i belive that when your computer boots you press F2 and the wireless card is automatically turned on

This IS the solution: Set it to use 802.11b _ONLY_ Do this in Windows: Start->Settings->Control Panel->System->Hardware->Device Manager->Network adapters->Intel(R) PRO/Wireless 2200BG Network Connection->Advanced->Wireless Mode = 802.11b only Driver version: 9.04.36 (04.04.2007) PROset/Wireless Software: not installed OS: Windows XP
