Tp link T2E archer wifi card not working

Support Network

Hi everyone! I’ve been distributing hopping and need to know how to get my wifi card to work, I’m new to Linux of any kind and this is my first distro that just feels nice, I might want to use this as a main environment over windows. But I can’t seem to get this wifi card working for the life of me,

i think you have installed the wrong driver, provide also output from:

so remove this:
pamac remove rtl88xxau-aircrack-dkms-git
install this:
pamac build rtl8821ce-dkms-git
reboot and test wifi

12

didn’t work i will have to continue this tomorrow

13

try different kernel, install the 5.10
sudo mhwd-kernel -i linux510
headers:
sudo pacman -S linux510-headers
reboot and select it in the grub menu, under advanced options

14

that hasnt worked either
im sorry for being of no help, i bought some cheap usb wifi thing and it works but barely, 100 kbs max

post output from:
inxi -xN

Are you sure you don’t mean T2U?

The inxi doesn’t show any wifi cards only ethernet - if it is T2U it is connected using USB and lspci will not list the card - use lsusb instead

lsusb

I have a couple of those TP-LINK Archer T2U and in my experience it does not work OOB.

I built a custom package for it - let me see if I can dig it up.

Using the provided output - specifically the device id - I did some searching - I was mistaken - the device is a pci device and seems to require special attention to get working with Linux kernel.

From a topic on AskUbuntu

It seems possible using sources from something called rtw89 which can be custom-built from AUR

As this is a dkms package - you must install the kernel headers for your active kernel as part of the process to get it running.
