Ubuntu – Ubuntu 20.04 issues with TP Link AC1300 Archer T4U

20.04driversnetworkingtp-link

I think this worked on the previous Linux versions, but with the new version, the dongle just doesn't get recognized. From the drivers offered on TP-Link's page, there is a Linux installation guide which doesn't seem to be working.

Anyone has any ideas if there's a way I can make this work? I have the feeling it has something to do with the new kernel…

There are several different hardware revisions, so first you'll need to figure out which one you have. There are a couple different methods:

  • Look at the the device

    • Either on the label of the device or on the metal where it plugs in should be the FCC-ID. The version is at the end of this value starting with V, for example TE7T4UV32 is v3.2

      For more information, see here: https://www.tp-link.com/support/faq/46/

  • Match the device ID

    • Plug the device in, and run this command: lsusb. You should see an entry like this one:

      Bus 001 Device 007: ID 2357:0115 TP-Link 802.11ac NIC

      The hardware ID should tell you which version you have:

      • 2357:0101: v1
      • 2357:010d: v2
      • 2357:0115: v3

Now you can install the driver depending which hardware version you have:

v1 and v2

These devices have the rtl8812au chipset and you should be able to do as Pilot6 suggested:

sudo apt install rtl8812au-dkms

v3

This device has the rtl8812bu chipset and you'll need to do a little more work to get it working. Thankfully there's a working driver available for it here: https://github.com/cilynx/rtl88x2bu

To get it working, you'll need to first install some packages and check out the Git repo:

sudo apt-get install build-essential dkms git
git clone https://github.com/cilynx/rtl88x2bu.git

Then follow the instructions here to install the driver:

cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

Note: I previously recommended the driver suggested by Diego (https://github.com/EntropicEffect/rtl8822bu), but I can no longer recommend that driver:

  • After resuming from suspend, it would no longer connect to wireless networks and I would have to unplug and replug the device
  • That driver is a fork of a fork and unfortunately there is no way to report issues
