meross AC600 usb wi-fi adaptor not working with newer Kernel (resolved)

I am using peppermint 8 64bit

We previously installed this wifi adapter and it was working fine.

I have not used the wifi for around 8 months but need to use it this coming week so plugged it in and the adapter was not seen by the system.

There have been 2 Kernel updates since it was installed and just to see I booted using the original Kernel and the adapter was working OK again.
How do I make it work with the new Kernel or do I need to remove the new kernels and if so how do I remove them or force the system to boot from the original.

As always any help would be appreciated.

Can you post the output from:

uname -a


dkms status


lsmod | grep rtl8812au

Can you post the contents of

xed /var/lib/dkms/rtl8812au/4.3.14/build/make.log

can you also run

sudo updatedb

then post the output from

locate rtl8812au.ko

I have updated the information you requested.

Could any of the fixes at this site help. GitHub - abperiasamy/rtl8812AU_8821AU_linux: rtl8812AU_8821AU linux kernel driver for AC1200 (801.11ac) Wireless Dual-Band USB Adapter

Hi Mark

I have resolved this by doing a clean install of Peppermint 8 64bit.

Now working OK but how do I prevent the Kernel being updated?

Thanks so far for your suggestions.

Well I’m not exactly sure what your problem is…

I just followed these instructions

In Peppermint 9 64bit (with both the 4.15.0-43 and 4.15.0-45 kernel) and the driver built correctly both times.

Maybe they fixed the driver (there was a commit 19 days ago) and you still had the old source code, or maybe it’s a Peppermint EIGHT problem (though it shouldn’t be if they’re using the same kernel).

Gimme until tomorrow and I’ll try the same thing on PM8

It now seems to be working OK so marked as resolved.
