USB Wifi fails to conect on reboot

[wizardknight]

I am having a bit of an odd issue, and I was hoping someone could suggest a possible work around.
I have a A95x (S905x) running the latest stable release.
It has the generic N wifi onboard which is functional, but slow at only 150Mbits max connection.

I have a couple of spare 1200AC USB adapters that use the 8812BU Realtek chipset. I see the same issue with both, and they work fine on my PC. I think they are fine.

If I connect to the router with the onboard wifi, I have no issue. I can then plug in the usb adapter and it is found and will connect without issue.
However if I reboot the system with the usb adapter plugged in, I can not see any wifi SSIDs on reboot.

I then have to remove the usb adapter, reboot, disable the onboard wifi, reboot, and finaly re-enable the onboard wifi to see any networks.

Does anyone know of a work around that will allow me to use the a 8812BU based USB adapter, and be able to reboot the system?

Did you try to disable onboard wifi (wlan0) by blacklisting it in
/storage/.config/modprobe.d/blacklist.conf ?

I had not.

Here is my lsmod output.
Is cfg80211 the correct module I should blacklist?

I figured out that the correct module was wlan. I would have expected the wifi module to be called something that looked like the chip set name. However after blacklisting wlan and rebooting several times I think i finally got the USB adapter to survive a reboot.
Thanks for the idea.
The AC card is easily 4x faster than the crappy onboard 150n. Makes a huge difference when waiting for my massive movie collection to load from the sql server.
