HP notebooks equipped with the Intel Wireless WiFi Link 4965AGN adapter may experience wireless connectivity issues after upgrading to Windows 10. The wireless adapter may connect successfully in 802.11g mode, but enabling 802.11n mode can result in system instability, including Blue Screen of Death (BSOD) errors.
