Have you retried with a more recent image? After I kicked them about the USB Ethernet situation Ndec enabled a few more drivers for the kernel in the Ubuntu images. Both my ancient Pegasus USB1.1 and a newer USB3 GBit card then worked out of the box.

The WiFi situation is indeed annoying and I've complained about it, they seem to be since looking into it, but as the driver is open source, someone else could check too and send patches. There even is a debug tool to intercept the proprietary QC driver commands (used in Android images). It should just be reconfiguring the filters away from their broken default state.

Yeah, I had a similar situation on the Hikey 96board. I ended up downloading their kernel source and building a bunch of additional modules so I could get USB Ethernet, as the wifi was basically useless there too.

Yeah, luckily that was very straight forward. Did that too before they released the new images.
