Wireless Joint

Sorry but where do I buy this model?

Need some router advice.

Which router to get out of these? (ZBT WG1608, Wodaplug H721, COMPEX WPQ618)
Is it possible to do multi wan bonding with ROOter GoldenOrb? Two M2 modems for example.

Does M2 to mPCIE reduce performance if so by how much?

Supposedly there is an improved real 5G version ...
