Upgrade to 24.04 failed - no networking

[oshunluvr]

I have an old Chrome Box that I converted to Kubuntu 18.04 a ways back. Upgraded it to 22.04 a couple years ago - no problems. When I tried the 24.04 upgrade, I have zero network capability.

So it seems I have neither driver available in 24.04. I rolled back to 22.04 (thanks to the btrfs gods).

The first thing I discovered is this in the 24.04 boot log:

[FAILED] Failed to start systemd-modules-load.service - Load Kernel Modules.

which might explain why I have no network. However, I went into 22.04 and this was in the boot log there:

[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.

so maybe it's a red herring.

Doing the above suggested command reveals:

stuart@asus-cn60:~$ sudo systemctl status systemd-modules-load.service
× systemd-modules-load.service - Load Kernel Modules

turns out this is a ACPI error relating to a sensor so nothing to do with networking.

So the network cards are:

Ethernet: RTL8111/8168/8411
Wireless: AR9462

The wireless card also has bluetooth and it's not working either. I guess I need to figure out why and what I need to get them back up.

What firmware (if any) did you use for Linux? It might need updating.

[oshunluvr]

I never had to install anything special before (18.04 + 22.04) so I have no idea where to start. The above errors are python script errors so I'm wondering if it's a bug or whatever. Everything I've seen so far says both network interfaces are supported by current kernels and no joy when searching on any of the errors so far.
