It didn't spring to life until after after I moved USB dongle to a different slot. I leave it be for now, perhaps next go round, I'll be repeating with the "possibly newer version" at the bottom of the last set of instructions...

Wifi didn't survive reboot, but revived upon moving to a different slot

So is it working now ?

It looks like the "newer version" is the same one from the repos, which didn't work earlier but may have just been the USB slot.

its working... but not gonna mark it solved just yet...  :-\

Might I also assume I'll need to go thru these motions with each upgrade of the kernel?

Theoretically NO, that's supposed to be the whole point of dkms (they get recompiled automatically against a new kernel) .. dunno what went wrong the last time though.

If they stop working after the next kernel upgrade, see if just running:
Code: [Select]
sudo dkms build -m 8812au -v 4.2.2
sudo dkms install -m 8812au -v 4.2.2
fixes things.

Stick with the default kernel unless you have a specific reason to change .. if you manually install 4.9 you'll have to manually stay on top of security patches.

Happpy to report relatively working wifi over the last few days. Each time I boot or reboot though, I have to pull out then re-insert the USB dongle. Seem to recollect reading something about the power down command along the way messing with Realtek chipsets...

Also noted that I now have two folders related to the RTL8812AU in my home folders now... which I perhaps need help clearing out after recollecting where they're supposed to be located?...

Those directories are deleted/removed. Gonna mark this as reSOLVED, as I'm letting myself become accustomed to letting the desktop stay turned on and allowing the powe management settings to put it into hibernation/suspend. The wifi dongle remains connected to the wifi network when returning from that state w/o having to be pulled out and plugged back in. I'll start a new thread if I begin having more issues with it later.

:o Well, I am quite frankly, stunned :o updated my Antec Aria desktop rebuild to Peppermint 8 two days ago with an ethernet connection. Wasn't expecting the wifi usb dongle to work without some fanagling. Turned it on this evening and noticed the blue light indicated it was working. Voila! I'm typing over the wifi network once again, without having to pester PCNetSpec... #KOW  8)

Seems a storm knocked out our power while we were away and the wireless WiFi usb dongle may have suffered...
Any particular reason you're not just installing it via the repos:
Code: [Select]
sudo apt-get install rtl8812au-dkms?

Decided to go back t this thread to see if I could get it fired up once again... but first intruction turned up an error:

Code: [Select]

As I plow thru the prvious set of intructions I realize I'm making one mistake...  but the terminal output provides a sigh of relief as it says:

Code: [Select]
spence@antec ~/RTL8812AU $ sudo dkms install -m 8812au -v 4.3.8

8812au:
Running module version sanity check.

Good news! Module version v4.2.2_7502.20130517 for 8812au.ko
exactly matches what is already found in kernel 4.10.0-28-generic.
DKMS will not replace this module.
You may override by specifying --force.

depmod....

DKMS: install completed.

Meanwhile, here's the rest of what I had done... and will now redo in a bit with proper kernel info...  ::)

Even as i scratch my concussioned head about modprobe?

Code: [Select]
spence@antec ~/RTL8812AU $ sudo modpobe -r 8812au
sudo: modpobe: command not found
spence@antec ~/RTL8812AU $ sudo modpobe 8812au
sudo: modpobe: command not found

ahhh, see mispelling
