Mint 18 Network Manager

Post by DEcosse » Mon Jul 25, 2016 2:55 pm

I have an Asus AC56 WiFi dongle using RTL8812au driver (which I had to manually install)

No problems with Mint 16 through 17.3 - Now with LM18, it does not work

I discovered through this - https://github.com/gnab/rtl8812au/issues/81 - that the Network manager in the new Kernel is to blame, that it does not recognize this family of adapters
Users have been reporting issues with NetworkManager not recognizing this family of wireless adapters after upgrading to NetworkManager 1.0.12-1:

https://bbs.archlinux.org/viewtopic.php?id=210868

Arch Linux Forum user V1del hypothesizes that this issue is being caused by the drivers not putting the devices into the correct management state, which conflicts with a patch introduced to the NetworkManager source tree in February.

How can I downgrade on LM18 and/or is there a fix that can be applied to the current version so it works with my Asus WiFI adapter?

(Incidentally if I use another WiFi dongle I can connect - speed on that one is really slow however, compared to what I was getting with my Asus adapter in the exact same location - only 25Mbps vs 90 - not sure if that is also related)

I used Synaptic to "force" the older version (1.1.93) and confirm my driver now works

I won't mark it "solved" since there is still an issue with the current version.

did you see this?.. http://askubuntu.com/questions/642794/h ... k-on-linux
It did not work for you on LM18?
You need to install a driver for this dongle. Connect to internet another way and run in terminal

sudo apt-get install git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
cd rtl8812AU_8821AU_linux
make
sudo make install
Then reboot, insert the dongle and test. If there are any errors while running comands, then post them to your question.

To set it up permanently run these commands

cd ~/rtl8812AU_8821AU_linux
sudo make uninstall
make clean
sudo cp -R ~/rtl8812AU_8821AU_linux /usr/src/rtl8812AU_8821AU_linux-1.0
sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0
The driver will be installed using DKMS.

If the driver is installed first time the commands are

sudo apt-get install git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
sudo cp -R rtl8812AU_8821AU_linux /usr/src/rtl8812AU_8821AU_linux-1.0
sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0
Linux Mint Mate 19.1 k/4.15, Windows 10, Manjaro 18.03 Xfce k/4.19.24-1 MX-Linux 18.1 Lenovo Ideapad G50-45 8GB

Thank you for attempt to help - however please note my opening statement

(I was actually one of the early adopters to utilize abperiasamy's build & in fact identified some performance issues with the original revision which he subsequently fixed and for which I was alpha tester; I've been running this adapter with earlier versions of Mint for 2-1/2 yrs)

However you don't even need that manual build (or even most recent variants of it) any more - you can now install directly from ubuntu package

Code: Select all

apt-get install rtl8812au-dkms
But that has nothing to do with the problem, which as stated is an incompatibility with the Network Manger
Please refer to the links (particularly the archlinux link) in the opening post for more detail on this issue.
And again, I confirm that down-grading the network manager 'fixed' the issue.
It is NOT an adapter driver issue.
