I have HP Pavilion n204tx laptop. It's been 2 years since I've bought it. The WiFi was working just fine while my windows 8 started encountering problems. So I went back to win7. Later on I upgraded to windows 10. But ever since I've gone back to Win7 the WiFi seems to have gone bad. The wireless network key doesn't work at all and my device manager also doesn't show the wireless as well as bluetooth adapter. Sometimes suddenly both get activated for some time and then they die. I've tried updating the HP drivers for my laptop and the respective OS. Every wireless driver I tried to install has failed installing.This seems to me as a adapter loose connection. Help me out.
