No WiFi Connection After Suspend

Ubuntu Version:
Ubuntu 24.04.3 LTS

Release:24.04 Noble

Desktop Environment
GNOME

Problem Description
Hi everyone. This my first post here and I’m a total Linux/Ubuntu newbie.

I’m using a Microsoft Surface Pro laptop which will no longer be supported by Microsoft as it can’t be upgraded from Win 10 to Win 11 as the CPU is not compatible. So I thought I would try Ubuntu instead of buying a new laptop.

Forgive the preamble, but I thought some background info may be useful.
I’ve not dual booted and am using a clean Ubuntu install which I managed OK.

A whole new world to learn, but I have my first problem that I can’t overcome with my severely limited knowledge. Whenever I come out of suspend mode, I have no WiFi and have to reboot.

I found some info here to create a text file and post it to pastebin, but I kept getting errors. Then I couldn’t access the txt file due to no permission (another issue). I did open it via Writer so I pasted it below this. My apologies if this isn’t the correct way. I assume it’s a driver issue or such maybe. In Windows, I could sort it, but this is a whole new board game :slight_smile:
I’m looking forward to learning though . . .

With many thanks

Just to offer some info about Microsoft Surface devices, there may be something pertinent here and also here

In the meantime, after suspend, you could try unloading and reloading the kernel module via the terminal:-

sudo modprobe -r mwifiex_pcie && sudo modprobe mwifiex_pcie

Thank you for your help and suggestions tea-for-one. I tried unload and reload of the kernel module, but it was still the same.
I followed the pertinent info links to install the linux-surface kernel
and that has cured the wifi problems and I can also now use the touchscreen.
There are some very clever people around who are able to write/code these things. Amazing!

Now the Ubuntu learning curve for me starts. I expect to make a few visits here as this Silver Surfer is keen to learn.

Thank you :grinning: :+1: :hand_with_index_finger_and_thumb_crossed:
