TP-Link Archer T3U AC1300 USB WiFi adaptor

Describe the bug or issue
I have bought the TP-Link Archer T3U AC1300 USB WiFi adaptor, it significantly boosts my WiFi signal. It does not work out of the box in neither Chromium OS (r92-r2) nor Ubuntu 20.04. Nonetheless I was able to make it work under Ubuntu following the instructions in https://community.tp-link.com/en/home/forum/topic/208022?page=1 .

First question first. Can USB WiFi adaptors be used with Chromium OS in general?

Describe your setup

  • Your Raspberry Pi model and spec variant, e.g. 4B with 4GB RAM
  • Your Chromium OS for Raspberry Pi release version, e.g. Chromium OS r92 r2
  • Your hardware configuration and setup, e.g. how you have wired the Pi board with any other peripheral connected to it - no, just external bluetooth keyboard and a wireless mouse. Both work fine.

To Reproduce
Steps to reproduce the behavior:

  1. Plug the TP-Link Archer T3U AC1300 USB WiFi adaptor in
  2. it cannot be used.

Expected behaviour
It can be used to boost the WiFi speed.

Additional context
The process of getting it work under Ubuntu involved compiling the driver and setting up dkms.

git clone https://github.com/cilynx/rtl88x2bu.git
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
  1. Can this driver be included in future Chromium OS releases?
  2. Can it be compiled within the linux environment under Chromium OS and then be used within the GUI?
commented

Well, I have made (a very limited) progress.

  1. I have found out that the kernel version available in the linux subsystem (4.19) does not match the kernel version used by Chromium OS (5.4.83 according to uname -a).
  2. I have also found the kernel you use (https://github.com/FydeOS/kernel-raspberry_pi) -- which seems not too big to be downloaded and unzipped (216 MB of the zip file) . I probably do not need all of it, but I am not experienced enough to know which parts exactly I need without trying it first.
  3. The Makefile in the rtl88x2bu driver has several options to use for arm devices (even one directly for RPi, even though I am not sure if this should be used in this case) -- Could you guide me which option to use, and I'll try to compile the driver when I have some time on my hands?

Support for specific peripheral devices is out of scope for this project, per the FAQ. I am sorry, if you find anything else useful you are welcome to share it here but I will have to close this for now.

I do understand and thank you for your answer.

Could you leave the issue open, just in case I it someone else can make some progress?

commented

And before I even try to begin, is it technically possible to use an external USB wifi dongle with chromium os @fydeos-alpha ?

I have no way of reliably finding that out..

commented

We have once used an unbranded generic USB wifi adapter and it worked. It states "802.11" on its enclosure and I remember it was quite small in terms of form factor. Chromium OS is actually an OS with the Linux kernel so yes of course it supports generic USB wifi adapters.

Maybe it's just because the AC1300 chips has limited mainline kernel support, it'd be ideal to replace with one that has known Linux support.
