Might be added in new image that will be released very soon.
I would still say 2-4 weeks. It is not our priority subject and we highly do not recommend it as wifi = more troubles.
Thanks, I'm just waiting for that, wifi is good and bad for various reasons, I know a friend that fried his PC because his lte router was struck by lightning, his lte router was connected directly to his computer via ethernet, yeah is rare but it happens in some parts of the world where lightning is constant, if you know how to do it properly, wifi is good, just make sure there are no more than 8 computers in your wifi network and where you live there are not many 2.4ghz radio connections, and you should be fine.
