Situation

I run Ubuntu 16.04 (4.15.0-48-generic) on my desktop and I would like to get my Netgear AC1200 WiFi USB adapter, model A6150 (with Realtek RTL8812BU chipset) to work.

I have followed the solution by chili555 in this SE question, and all the steps terminated successfully. I.e. I have installed drivers from this repo:

https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.2.4.4_26334.20180126_COEX20171012-5044.git

And I have rebooted my system.

Problem

It doesn't seem to work, i.e. when I unplug the ethernet cable I loose my connection (with the dongel in). I don't know what to do now (and I am very new to linux).

More info

  1. In the All Settings>Network I don't see anything wifi-related. Does my desktop need to be setup for to use wifi somehow?

enter image description here

  1. Output of lsusb (among others) show that my dongle is found

Bus 002 Device 005: ID 0846:9055 NetGear, Inc.

  1. Outout of lshw -C network (entire output)

  2. rfkill list all doesn't output anything.

Updates (e.g. based on comments)

  1. sudo modprobe 88x2bu doesn't produce any output. I.e. it instantaneously asks for the next input, without outputting anything.

  2. Output of dmesg | grep -i rtl

Do this in terminal

sudo dkms uninstall rtl88x2bu/5.2.4.4
sudo dkms remove rtl88x2bu/5.2.4.4 --all
sudo dkms uninstall rtl88x2bu/5.3.1
sudo dkms remove rtl88x2bu/5.3.1 --all
git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu</pre></code>
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

Reboot

  • This worked just as I had hoped! Just so I understand what went wrong and what you did - is this correct: I had tried to install two different (old) drivers that were in conflict. If I had installed either of them correctly it would still have worked (?). But your fix was to uninstall everything and install the most recent version of the drivers? – Toke Faurby Sep 06 '20 at 21:12
  • PS I think there is a typo in line 7. I used VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) from the github repo instead – Toke Faurby Sep 06 '20 at 21:13

    The older versions did not have your device listed at all but I found it in the newest version. I put line 7 exactly as what you used but there must be something in the format that removed some things. Changed the code tags a bit and it shows correctly now – Jeremy31 Sep 06 '20 at 21:18
