Wifi not working in ubuntu 20.04

Ask Ubuntu Asked by AnxiousConcert on December 12, 2020

WIfi is connected but there is no internet in ubuntu only. Wifi works in windows dual boot so I know it is not a hardware problem.
Main problem is disconnectivity. The internet stops every 1 to 2 minutes and this only happens in ubuntu.
Solutions I have tried so far:

  • Disabled power management for wifi

  • Reloaded in built drivers using sudo modprobe -r ath10k_pci sudo modprobe ath10k_pci

  • Restarted network manager

  • Disabled ipv6 settings and set ipv4 to automatic DHCP.

Pasting the output of iwconfig

enp2s0    no wireless extensions.
