WiFi network connection problems

[Guillou1976]

Hi, I have a old Asus laptop.

He ran under windowd 10.
Now I put Linux mint cinnamon 22.3 on it.
It looks good but I have internet only wired.
The integrated WiFi card is well recognised but after 1 minute connected on my WiFi network, the connection is down and on the connection manager it is writted unavailable

All updated was done with my wired connection.
So the computer is completely updated.
And each time I turn off the computer, the computer find my WiFi network and less than a minute he lose the connection, can't find any network and put the WiFi unavailable.

I can't use the computer wired I have no working place to use it likes that.

I think to buy a usb/WiFi dongle like TPLINK ARCHER T3U.
But following the TPLINK support this device is not compatible with Linux mint.

So, do you have any recommendations for a compatible usb/WiFi dongle.

My usb port supports usb 3.0 and I need a fast device.

Thanks for your help.

I've noticed that Wi-Fi receivers are among the most frequently damaged components in laptops.
Many Wi-Fi receivers also work well on Linux, but they require proprietary firmware, and that might not be good enough.
In some cases, to avoid compatibility issues, perhaps to get more signal strength than standard USB dongles (excluding those with antennas, which could be inconvenient), I get an access point with antennas (which I set as a client) and then connect it to the PC with an Ethernet cable. This eliminates compatibility concerns and generally provides a better signal.
obviously this solution only if it is kept almost always in the same place at home or in the office, if you have to carry it around it is inconvenient and a USB/WiFi dongle is better.
in one case where I saw that it didn't have enough signal with a basic one (since he had to move the laptop often) and needed a larger one with antennas but it was uncomfortable then I put a small USB extension cable on it, so I can move it quite easily to other rooms but it still has a good signal.
About "TPLINK ARCHER T3U" I've never had users who have it so I can't tell you, from a quick search it seems possible even on Linux but it could require manual operations, so if you're not very experienced I would recommend you look for another one with out-of-the-box compatibility (if you buy a usb/WiFi dongle)
