Update killed my USB WiFi adapter RTL8821AU

[richyg]

Linux noob here. I had previously followed this thread to get the drivers installed and working, I think possibly from this source https://github.com/diederikdehaas/rtl8812AU

AFAIK I didn't have it set to update automatically after a new linux kernel update (through dkmks?) so after the update my WiFi is no longer recognised.

As per advice here is my wireless-info.txt http://paste.ubuntu.com/p/7PYCBkPVB3/

Hoping this will be an easy fix and maybe to have the driver working after another such update without having to sort it manually.

Thanks in advance.

Please run and post:

sudo dkms status

I suspect that the dkms rebuild process went wrong.

[richyg]

Thanks for your help.

result:

rtl8812AU, #MODULE_VERSION#: added

I know that looks wrong, probably as a result of me tinkering away trying to sort this myself rather than asking for help.

FYI the downloaded files for the driver (from github I presume) are located at /home/richard/rtl8812AU

Thanks

Please run:

sudo dkms remove rtl8812AU/#MODULE_VERSION#

And, assuming there is no error, warning, etc., show me:

sudo dkms status

I hope it returns a blank.

If there is a warning, error, etc., please post it.

sudo dkms remove rtl8812AU/#MODULE_VERSION# --all

I normally change some of the dkms.conf so that dkms can be used normally

PACKAGE_NAME="rtl8812AU"
PACKAGE_VERSION=1.0
BUILT_MODULE_NAME[0]="8812au"
MAKE="'make' KVER=${kernelver}"
CLEAN="'make' clean"
DEST_MODULE_LOCATION[0]="/updates/dkms"
AUTOINSTALL="YES"

Then I just do the

sudo dkms add ./rtl8812AU
sudo dkms install rtl8812AU/1.0

The instructions on the github site show

DRV_NAME=rtl8812AU
 DRV_VERSION=4.3.20
sudo mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
git archive driver-${DRV_VERSION} | sudo tar -x -C /usr/src/${DRV_NAME}-${DRV_VERSION}
sudo dkms add -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms build -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms install -m ${DRV_NAME} -v ${DRV_VERSION}

UPDATE: OK so I managed to delete the folders manually from /var/lib/dkms/ and /usr/src

I should have waited for further instructions but I tried following the install commands from the Readme (carefully) but the WiFi is still not working after a reboot. Here is the transcript:

That looks good, so reboot and post results for

modinfo 8812au

Hopefully it works

[chili555]

Please post:

lsusb

And also:

modinfo rtl8812au | grep alias

[richyg]

Okay here are results from the commands in the two posts above. The last result doesn't look too good.
