How to install WIFI-adapter TP-Link AC1300 archer T3U in Ubuntu 20.04 LTS

I'm really new to Ubuntu. My laptop WIFI is stuck on "airplane mode on" and I'm not able to turn it off. I thought the HW is damaged and therefore I bought a new WIFI adapter HW. The adapter installation disk only run on windows and mac.Not in Linux I have tried some Linux commands I found on the internet to the install drives but without success. Can someone help if he thinks that the new adapter is the solution?

Thanks Skeyes


To reset "Airplane mode", Find the hardware switch, or a Fn key combination. Carefully read the keycaps, and the symbols along the keyboard frame just above the keys.
