Internet not working on functioing WiFi adapter TP-LINK TL-WN722N V2.0 - Dave Bruwer - 01-31-2021
I have just installed Linux Lite on an old desktop PC.
It uses a TP-LINK TL-WN722N V2.0 USB adapter for WIFI access.
The wifi seems to be working fine, and I was even able to access local shared files over the wifi.
BUT, the internet connection doesn't seem to be working.
I can't see anything obvious wrong.
I connected to the modem with an ethernet cable, and performed all the updates, but to no avail.
Any suggestions?

What DNS are you using?
What is the output of:
Code:
route -nand

Not sure what you're like installing drivers, but this looks very well suited and optimized - https://github.com/abhijeet2096/TL-WN722N-V2 only do 1 -7, nothing else! Hopefully it will work with the current kernel. Take note of the section 'Activating/Deactivating LED' before you do step 3.

Thank you for finding that.
I might need a bit of help understanding what i am doing.
When I try to do step 4, I get this message:
(also, see attached make.log file)
Code:
sudo dkms build -m 8188eu -v 1.2

Try this one - https://gitlab.com/kalilinux/packages/realtek-rtl8188eus-dkms click on the Download button next to 'Clone' and select 'build'. You should have a file called master.zip, extract the .deb file from that zip and double click on it to install the driver.

That one installed successfully, but unfortunately the problem persists.
It is quite interesting that the internet works fine over ethernet cable, and the WIFI seems to work fine for shared local files etc., but the internet just won't work over the WIFI. :-\
