I don't mean to hijack this thread, but in case you missed it and looking for the Ubuntu 22.04 Jammy Jellyfish driver (kernel 5.15.0-27-generic). You may try this workaround instead. I hope this helps.

Edit: I have successfully tested this driver with T3U Plus and T4U.

Do you still need help?

I had the same problem as you and i was stuck for housrs.

But its a secure boot problem. I turn it off and it allowed me to install it and it works.

Im using ubuntu 22.04 and it works perfectly

  @MonkeyDLuffy Hi a newbe question. How do you do that if you don't have internet. I have a usb stick that I could take to a friends house to download the file from Git, but how do I get it to work on the linux computer at home from USB?

Hi

Followed all the steps except I had already installed the card onto the motherboard.

So after the installation, the wireless card is not found, is this due to the fact that the card was already in the machine when the driver was installed?

The installation instructions state to "Make sure the adapter is unplugged"
Do I have to tear open the case pull the card do the installation and then plug in the card?

Is there just a command I can invoke to tell the OS to look for the new device without opening the case?

Thanks.

  @jw4wellness you can share internet to the pc by use USB tethering with your phone 

Hi,

I'm a beginner on ubuntu, so sorry if I'm asking stupid questions, I followed your instructions but it doesn't work, I think it's because you need the internet for it to work, but that's why I'm trying to install Archer T3U, is there a solution to install Archer T3U without internet connection?
