New PC, never had WiFi working on it before. Ethernet works fine. Trying to use Alfa AWUS036AC which uses RLT8812AU. Initially tried to update driver with Software & Updates > Additional Drivers in Gnome, didn't work, no response from adapter. Went searching and found info about adding:
[device]
wifi.scan-rand-mac-address=0
to NetworkManager.conf but that didn't work. Uninstalled the rlt8812au-dkms driver and installed the one from https://github.com/gnab/rtl8812au and now I can see the WiFi adapter using tools like iwconfig, lsusb, etc. and it shows in the system center, giving me the ability to turn it on/off, connect, etc.
The only problem is - it never connects, it tries but fails repeatedly. I monitored Network Manager and found that there was an error setting powersave 1 and I searched and found something to address that (sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf) but now I get error setting powersave 0. I don't know if the command I ran made things better or worse but that appears to be my only error while trying to connect.
I ran the network troubleshooting script and have it pastebinned for someone to look at @ http://paste.ubuntu.com/24798045/
Hopefully I didn't leave anything out - I'm new and frustrated and ready to move on to the next issue once this one is resolved.
