It was cheap, and it was "Amazon's Choice" - So I suppose someone is making a little extra profit...
I don't necessarily hate or love these RealTek chips. I haven't formed very strong opinions about WiFi chips. I've bought a ton of the Edimax EW-7811Un USB WiFI adapter things. They are small, cheap, and they just work every time. But they are only 'N' WiFi at 150mbps. New 'AC' WiFi adapters can hit gigabit speeds supposidly. So I suppose I really just wanted to start looking for a new favorite.
Anyway, I tried to compile a kernel with a rtl8812au driver... but that was difficult. Then I found MrEngman!
sudo wget http://fars-robotics.net/install-wifi -O /usr/bin/install-wifi sudo chmod +x /usr/bin/install-wifi
sudo install-wifi -h
What a life saver! Thank you MrEngman and everyone who worked to make my life easier. You are all heros in my book for writing such a usefull and well written script to install WiFi drivers on Raspberry Pi's.
Seriously made my day, cheers to you!
PS: Their script works with MANY different RealTek chips.
