Ethernet & USB Dongle not working

Question

My machine running Ubuntu 22.04.2 LTS is unable to connect to the internet. The ethernet and Wirless dongle do not appear as options in the settings and I'm unsure on how to fix this

The wireless dongle is a TP-Link AC1300

Browsed heavily through other posts and nothing seems to work

Here's some information which I've seen requested in other posts

lspci -knn | grep Eth -A3:

ifconfig -a doesn't show the Wireless dongle or Ethernet

I was attempting to install the Realtek drivers while offline but after follwing the README file I get this when trying to run their Shell script:

sudo ./autorun.sh:

Check old driver and unload it.
Build the module and install

No driver exists!!!

I've also seen this post which has a solution which I want to try but I'm unsure how to modify the solution for my Realtek devices

Please let me know if you need further information and thanks in advance

Answer 1

Jeremy31 had the answers here

Looks like the kernel version was problematic (v35), most likely due to some updates which weren't properly completed before a crash happened

Restarted the machine and held down Shift to open the GRUB menu, go to advanced options and load an older Kernel version (v28 in my case)

Once loaded, everything was working. So I ran the following to repair the v35 Kernel:

sudo apt install --reinstall linux-modules-extra-6.5.0-35-generic

Once completed, restarted and all worked well!
