Im running ubuntu 20.04 and have a AR9287 wireless adapter installed, I recently did a fresh install of both windows 10 first and then ubuntu. Windiws recognizes the card straight away but ubuntu fails to show any wifi options.

I tried these steps aswell but didnt work: https://itsfoss.com/fix-no-wireless-network-ubuntu/

Connecting to a rounter via ethernet does not work. Connecting a usb tetherded connection also does not work.

I ran the diagnosis script and described here: My wireless/WiFi connection does not work. What information is needed to diagnose the issue?

Diagnosis results: https://pastebin.ubuntu.com/p/Q2dtxMkbgv/

Any help is deeply apreciated.

  • Kernel modules are not installed for some reason. Was installation interrupted, or an interrupted upgrade? – Pilot6 Oct 26 '21 at 09:37

You are missing the linux-modules-extra for the current kernel,download http://archive.ubuntu.com/ubuntu/pool/main/l/linux-hwe-5.11/linux-modules-extra-5.11.0-38-generic_5.11.0-38.42~20.04.1_amd64.deb and copy it to a thumb driver/sdcard and put it on Ubuntu desktop, then double click to install, then reboot
