wifi: RTL8811CU (works!)

I just thought I would post my success story with a RTL8811CU USB wifi adapter on the kiwi. I had previously fought hard to get a MT7601 working and while it worked I had some stability issues. The RTL8811CU is cheap and getting it working was easy. I cracked the case open on mine and soldered a connector to be able to use an external 2.4GHz antenna (my kiwi is in a metal enclosure).

In a nutshell:

sudo apt-get update
sudo apt-get install -y build-essential dkms git
git clone https://github.com/fastoe/RTL8811CU.git
cd RTL8811CU
make
sudo make install
sudo reboot

The make step takes a while, like 20-30 minutes. Once you reboot, configure with connmanctl:

robot@ev3dev:~$ connmanctl
