TP-Link AC600 Archer T2E PCIe card is not recognized by Ubuntu 20.04

sd flag

I recently purchased a new TP-Link AC600 Archer T2E Wireless Dual Band PCIe Adapter for a new build. I have tested this card in 2 machines running Ubuntu 20.04, but I've gotten the same result. I couldn't even get the light on the bracket of the card to signal, leading me to think it was defective. To be sure, I put the card in yet a different machine running Windows 10, and it worked without hesitation.

lspci appears to recognize the card as "Network controller: Realtek Semiconductor Co., Ltd. Device b821" which is incorrect. I am currently on kernel 5.15.0-60-generic.

~$ lspci -knn | grep Net -A3

You need to install drivers for it. Connect to the internet by other means and run

sudo apt install build-essential git
git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make install

You'll have to make and sudo make install after each kernel upgrade.

But the 22.04 Ubuntu release with a HWE 5.19 kernel will support the device initially.

This set of drivers didn't work. After attempting this solution I did some additional digging with other drivers, but have had no success. I will put 22.04 on my new build and see it if works that way. Thank you for your help!

This driver should work. Did you disable Secure Boot?

I did not disable Secure Boot. I installed 22.04 on my new build instead and the device worked correctly (as you stated it would). The only reason I had instated 20.04 LTS initially was because I had a boot drive made and available to me.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
