Can't get TLWN722N V1 with AR9271 chipset to work on Lubuntu 19.10

Ubuntu

I’ve got an TLWN722N with AR9271 chipset which doesnt work on Lubuntu 19.10.

I have the Ubuntu installation on an external hdd, so I ran it on another dell computer and the wifi adapter started working perfectly, but when I try on my hp 8460p computer it doesnt work.

The wifi adapter is recognized when I type lsusb and I can see ath9k_htc when I type lsmod.

Until now I’ve found many asks on forums related to this in some way, but most of them aren’t solved and what I’ve tried from solutions given on them doesnt work for me.

Last thing I did was trying to install firmware-atheros, following the instructions given in this site: https://linux-gobmis.readthedocs.io/drivers-wifi.html

I got to install it but it didnt make any change on my problem. I rebooted the computer but it didnt work.

Sorry for my english, Im spanish and I started using Linux about 1 week ago.

Edit: The problem got solved; I though my laptop didnt have an internal wifi adapter, because it never worked on Windows but I dissasembled it and after I noticed that it was there, I entered the BIOS and restored to default configuration. Now the Internal Wifi and the TP Link USB Wifi are detected.

Thank you for your help.

All that I read in your post suggests me that the wifi is really working right for you, you just can’t setup the connection.
You may need to get rid of LXDE own network manager, and istall Gnome network manager instead:

Purge wicd*:
sudo apt purge wicd*

Install Gnome network manager:
sudo apt install network-manager network-manager-gnome

Reboot then, and try to setup your wireless network. I may be wrong, let me know please if this worked for you.

I recommend to be super careful with purging packages, especially when those are system packages so crucial to the basic functionality of the OS. Additionally, I only had good experience with wicd, so it is hard for me to imagine a problem with that piece of software.

@s4maritan

What do you mean by “the chipset does not work”? Judging from the command outputs you posted, everything seems fine. Can you not establish an internet connection or what exactly does not work?

When I did dpkg -l | grep network-manager I noticed that I already had the gnome network manager installed, not the lxde network manager.

I think this is a problem related to my computer, because I run the same system with my external hdd in my brothers computer and once I connect it, starts working just fine and detecting the networks.

When I connect the wifi card to my computer it is detected but there arent wifis detected, I got the driver and the firmware installed, and I thought that if the driver or the firmware were corrupted the same installation running on my brothers computer wouldnt have worked.

Yesterday I noticed that if I type ifconfig wlx10feed24713e up the wifi cards light turn up, but it doesnt starts working anyways.

I dont have an internal wifi adapter in my computer, I can just use the ethernet.
