Need help installing EDUP wifi driver

Hey y’all! I bought a EDUP usb wifi card off amazon and, at first, it worked. I restarted my computer after an update today and now the wifi isn’t working at all.

I had rtl88x2bu-dkms-git from the AUR downloaded and I’ve tried redownloading that a few times. Whenever it tries to use dkms it gets this error message

==> dkms install --no-depmod -m rtl88x2bu -v 5.8.7.4.r129.15c214d -k 5.11.19-1-MANJARO
Error! Bad return status for module build on kernel: 5.11.19-1-MANJARO (x86_64)

==> depmod 5.11.19-1-MANJARO

and then just finishes.

I’m really confused by this. I’ve rechecked a bunch with lsusb and yeah it’s realtek rtl8810bu. If anyone has any idea let me know. I tried searching on the forum but didn’t find anything. Thank you!!

Hello @maryball :wink:

Looks like kernel v5.9 is not uninstalled properly. Remove it completly

Mate!! Thank you so much!! So it wasn’t just 5.9 that was improperly done it was also 5.11. I upgraded to 5.12 and uninstalled both 5.9 and 5.11 and that fixed it!!! Thank you so much!
