None taken.
The motherboard (if it is EVGA) is not custom built and unless EVGA fabricated their own wireless network components, that part is manufactured by somebody else.
On this little Compaq laptop I am resurfacing I have no CDs to reinstall any drivers either but I can see that the wireless adapter VENdor is 8086 and the DEVice is 4220 so that makes it an Intel 54 MBit/s Notebook WLAN Card.
To get drivers for that, I would not go to Compaq but I would instead go directly to the Intel site and get their latest drivers (which I did) and the wireless is now working perfectly fine and it took less than 10 minutes to get that working. Not two days and still no wireless (no offence :-)).
If I can't identify hardware or where to get drivers (or people are not sure what they have), if I can get the info from Device Manager, it is usually easy to find the drivers.
Besides I generally give up on following topics here when the problem is not successfully resolved after two pages of trying so maybe you will get it figured out (I'll just lurk).
