I got this trouble with WIFI connection. At the beginning just turn off when my laptop was on for 2 or 3 hours, and i needed to reboot.

But, i tried to fix it and just become worst. I follow this steps: https://www.taringa.net/+linux/realtek-8723be-wifi-ubuntu-solucionado_v6xou and my WIFI turn off. Don't work anymore.

I tried other solutions of the HP official page, but nothing works. Please,if there exists some way to return to got 2 or 3 hours of connection, just let me know. I really need (or can) return to default values for WIFI?

What information you need to help me? Also let me know.

I adjunt my wifi-info-script

  • Please see: https://askubuntu.com/questions/762254/why-do-i-get-required-key-not-available-when-install-3rd-party-kernel-modules You probably should disable secure boot. – chili555 Jan 25 '19 at 14:42
