Driver for rtl8811cu?

[tpkellis54]

Hi All

Whitebatman rtl8811cu driver works for me. Wow. So i now have blazingly fast wifi 100 plus mbps on 5ghz 882.11ac wifi usb donle. Amazing.
i just followed Whitebatman instructions (had to find out how to clone github but its easy) and it worked. Wonderful.

Guess the driver thingy for rtl881cu is solved now!!!!

Thks to Whitebatman's driver (RTL8821CU), it works for my RTL8811CU (yes, the chipset no. don't tally but it works). For my case, I have to do this in Terminal:
sudo apt-get install linux-headers-generic build-essential git
sudo make
sudo make install

I didn't try with DKMS. FYI, my USB dongle is a generic no brand 600mbps dual band AC adapter (bought cheap from eBay). Got it for my HTPC (an old Dell Optiplex Core2Duo desktop).

I've managed to build the driver by modifying Makefile in kernel headers. It isn't the best possible solution, but it works. You can find my workaround in readme of my repo.

Mate! Thanks you so much for all the work you've put on it! Just made my day happier

Cheers!
