If you have an Intel Centrino wireless adapter, and get a Blue Screen of Death, update the driver to version 15. 13.x and 14.x can generate BSODs especially when connecting to commercial Access Points, like Alcatel’s.
netw5ns64.sys (or related errors) come up on the BSOD screen. Windows doesn’t update to the latest Intel driver, that’s the problem. Microsoft Update tells you it’s got the latest, but that’s untrue. You have to go to www.intel.com and check there for the latest driver for your Intel WiFi card.
