Hi, you cannot attached files in github issues. Post it to https://gist.github.com/ .

You had same repo in `/etc/apt/sources.list` line 2 and 4, remove one of them.

Hi, `0bda:b812` is the default ID, it had already in the driver. What is the result after run `modprobe 88x2bu`?

Check `dmesg` output, your kernel may not allow unsigned modules to be loaded.

You have to compile and sign your own kernel in order to use it with secure boot. The distribution's private key is not publicly available, so you cannot sign self-compiled...

You can try run `modprobe 88x2bu` and see what happened in `dmesg`.

I never able to reach 800 Mbps. In my high density WiFi area I can do about 400Mbps if I enable USB 3.0. https://github.com/RinCat/RTL88x2BU-Linux-Driver#usb-30-support

It should shows DOWN if you are not connected to any WiFi, that is not an issue. The driver is successfully initialized and you have `wlp2s0f0u7`. You should check NetworkManager...

I don't see any suspicious, and this one has nothing to do with MTU. NetworkManager did found the interface, I don't know why it did not shows.
