RTL8188EU not recognised after upgrade

[Hume2]

Today, I upgraded the system using yay. After that, it doesn’t recognise RTL8188EU as WiFi module. It did before the upgrade (otherwise, I wouldn’t be able to run yay). If I recall correctly, I upgraded the system something like one week ago, so it must be a bug introduced recently. I installed https://github.com/lwfinger/rtl8188eu before the upgrade.

So now I’m without internet again. What shall I do?

Is there are least a way to undo yay?

I installed https://github.com/lwfinger/rtl8188eu before the upgrade.

If you updated the kernel then the old driver module will no longer exist.

I’d recommend using a DKMS module instead, then it will be compiled for each kernel version. For example, 8188eu-dkms-git or 8188eu-aircrack-dkms-git.

Or, just reinstall the module manually as you did before.

I tried reinstalling the module before. Now I tried to build it again and it works now, thanks!
