Blue Screen ndis.sys w22n51.sys Intel PRO/Wireless 2200BG

For those who spent hours to solve this Blue Screen of death..

Yesterday I spent like 8 hours or more to find out why my sick old laptop crash when I turn on the wireless radio switch..

The problem is: w22n51.sys

Even tough at first it said ndis.sys, but when I turned all services off the BSOD still happens and said w22n51.sys instead.

Many people couldnt solve this because everywhere on the internet they share the old buggy driver, even on the laptop manufacturer website (mine is acer)..

Intel have fixed this bug on 2009, and post the driver on their website.. So if you have same problem with mine, just go to intel websites and search for new driver for this Intel PRO/Wireless 2200BG and try it..

For me it solved my problem, no more bsod when I turned on the wireless device..

NOTE:
- many ndis.sys BSOD is simply solved by switching hardware slots (mostly memory)
- many ndis.sys BSOD is actually a different driver problem, so try turn off all windows services and see if the BSOD still happens and caused by other thing.
- turned off all services is done from msconfig (start->run->msconfig), on services tab click disable all services

good luck
