Internet not working on functioing WiFi adapter TP-LINK TL-WN722N V2.0

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.  :-\

Did you read the entire page?

I'm curious about what's going on here. If you like, install Teamviewer from Lite Software, run Updates then send me the ID, pass via a PM here.

Solution for those with an already functioning WiFi, but no Internet. Disconnect Ethernet if connected.

Remove any existing WiFi connections from Edit Connections in Network Manager. In this case it got rid of duplicate IP's on the one adapter.

Set some reliable DNS:

Code:

sudo mousepad /etc/resolvconf/resolv.conf.d/head

Code:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save.

Set IPV6 to 'Ignore' in Network Manager.

Reboot with Ethernet cable NOT plugged in.

Should be good to go
