This article is regarding how to install the Edimax EW-7722UTn v3 adapter in Ubuntu/Mint. We use Ubuntu 22.04 Kernel v5.15.0-58 in this instruction. This instruction is confirmed in Mint 21 Kernel v5.15. As of Jan 24 2023, the official Ubuntu driver on our website can only support kernel up to v5.8.0. Therefore, we need to use open source driver on GitHhub on https://github.com/kelebek333/rtl8192fu-dkms. Thanks to kelebek.
We recommend you check kelebek's web page for updated information.
