WiFi connected to network, internet not available - Tribolonutus - 06-10-2020

I'm having the same issue as in this topic: https://www.linuxliteos.com/forums/network/wifi-issue-in-linux-lite-5-0/.

I'm using TP-Link TL-WN722N. On live USB its working, but after installation system is showing me that it is connected to the network, but internet is not available.

Following request by user Jerry, response is as follows:

Hello.
I cannot help much about your problem but I know that rfkill list all has to return something, and if it doesn't, something is definitely wrong.

The output should be something like this:

Code:
0: phy0: Wireless LAN

    Soft blocked: no

    Hard blocked: no

1: acer-wireless: Wireless LAN

    Soft blocked: no

    Hard blocked: no

2: acer-bluetooth: Bluetooth

    Soft blocked: no

    Hard blocked: no

3: hci0: Bluetooth

    Soft blocked: no

    Hard blocked: no

I notice there are many network issues with Linux in general, not just Lite, same as described in the OP. I tried several distros before settling down with Lite, and I had the same problem with some of them (Mint, MX, even Lubuntu), not just with networking, but with touchpad, keyboard, etc...

Looks like the live environment is kind of a demo mode, to make you want to install. Once you've done that, you discover that what worked perfectly when running live in RAM doesn't work anymore, and that's why Linux has trouble gaining traction with the average user.

Those things should work out of the box 99.9% of the time, barring your running some exotic hardware (I have not-so-fond memories of Alps touchpad on Toshiba laptops working perfectly in Ubuntu live, then completely falling apart after install). That's far from the case.

Users should be able to save the live environment parameters and settings upon install, instead of having to customize their install from scratch. Once the partitioning is done and the users are created, I don't see why an option to save the current (live) parameters and settings could not the offered to the user.

My two cents on the subject. I have enough irons in the fire myself with Lite at the moment... :-)

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/tp-link-tl-wn722n-driver-stopped-working?noredirect=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:
'https://ninja4it.wordpress.com/2015/04/05/inside-linux-and-wi-fi-atheros-ar9271-drivers/´

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