WiFi connected to network, internet not available

Hi Tribolonutus,
Please go to this link and try the v3 driver of your TP Link TL WN722N wifi adapter.
`https://static.tp-link.com/2018/201805/20180521/TP-Link_Driver_Linux_series7_beta.zip`
It supports linux kernel 2.6.18 ~ 4.4.3
Support monitor mode on ubuntu and mint.
It is a beta driver.

There is a unanswered post about this on the tp link community forum: ´https://community.tp-link.com/en/home/forum/topic/213386´

Based on another post I would suggest you to try the following commands: https://askubuntu.com/questions/1263591/...ct=1&lq=1´
Does the driver load automatically, as expected? Check:
lsmod | grep ath

If not, try to load it and see if there are any errors or warnings at the terminal:
sudo modprobe ath9k_htc

If it loads without complaint, check to see if a wireless interface, ideally wlan0, was created:
iwconfig

If no wlan0 is created, see if the message log has any clues:
dmesg | grep -e wlan -e ath9k

Do you have installed the linux-firmware package?

At last, this guy seems to solve the problem installing another network manager called wicd:

Although the post are five years old I think they could help.
