[SOLVED] Wifi adapter not detected

Post by bradeythedev » Mon Jan 24, 2022 11:24 pm

Hello everybody, I have recently installed Linux Mint XFCE on my PC. After managing to get it to boot, I realised I could not connect to wifi, as when I select the wifi tab it tells me no wifi adapters are connected. I have since installed Nvidia drivers (with the driver manager), Budgie DE, and written this forum post by USB tethering from my phone. I also had a shot at installing https://github.com/xtknight/mt7610u-lin . wifi-fixes and https://github.com/aircrack-ng/rtl8812au drivers, with no success. The instructions were not entirely clear, so if you have some better and more detailed methods, please share them. I have a «TP-LINK Archer T2E Wireless-AC600 Dual Band PCIe Adapter» which worked fine when I was using Win11. This is the result of the command «iwconfig»:

usb0 no wireless extensions. lo no wireless extensions. 

When searching about drivers, I have seen the word USB tossed around a bit, so is it worth mentioning my adapter has a female port which screws onto the circular male port on the PC (definitely NOT a USB)?
Any help is appreciated — I don’t think USB tethering is a very good permanent solution. Thanks

Did you try it with tethering disconnected?

Also, can you post what this shows:

Everything points to that using the RTL8821CE chip.

Run the following, 1 line at a time:

sudo apt install git dkms build-essential git clone https://github.com/tomaspinho/rtl8821ce.git cd rtl8821ce sudo ./dkms-install.sh
