Power cuts and surges make computers do strange things,
If it's on your desktop, try.. Pull the USB Wi-Fi from the machine, wait 20 seconds and put it back, it may sort itself out,
if it's on a laptop, check that hard block has not been invoked [flight mode switched on]
unfortunately does not work like that...
 
not sure how this should help. I tried restart router it didnt help. funny but even ChatGPT wont give me the right answers...

Did your kernel get an upgrade? if so your - make dkms_install - may no longer be there since it was installed to that specific kernel because inxi -N is not showing your rtl8812au - dkms usually generate Linux kernel modules whose sources generally reside outside the kernel source tree. The concept is to have DKMS modules automatically rebuilt when a new kernel is installed.
But sometimes this does not happen - why - there is probably a thousand different reasons as to why

If that is the case you will just have to rebuild it again

Also on your image it is showing - that your Ethernet is connected

from the routing perspective, while possible, it is not ideal to have addresses from the same network in different interfaces.
Routing expects a different network per interface, and ultimately one of them will take precedence over the other in routing, since they overlap. This may be why your WiFi is not working - The solution I know is having more than one interface connected to the same network is to aggregate them together in a bridge interface

tbh I dont know about kernel upgrade. but I have this error message when I hit dkms_install.

so how may I rebuild dkms module?

Regarding "Ethernet is connected" I connected my OnePlus to share internet via USB.)))
 
Has this worked for you as expected?
 
I will have to give a try.
