I'm in! :) Where do I get all this magic?
I'm also on an AX210 in an ideapad. I'm on current that's about a year out
(kernel/world). So as I perform the world/kernel dance I want to get the
right driver setup. Sorry for all the questions. But the WiFi page is a
year out of date. You indicated fwget(8) as the procedure. But I build
*everything*. So not an option. It seems it'd also be hard for a first
time install where you (as yet) have no connectivity. :)
Anyway. Is it enough to add net/wifi-firmware-iwlwifi-kmod to PORTS_MODULES
in src.conf?

Thanks, and thank you very much for all the work you put into this!
