It's almost like that list is ... all of the options.

No. /FLAGSHIP/ models certainly have a high chance of supporting
802.11ax, but that doesn't mean "any" phone.

Again, what are you *REALLY* trying to ascertain here? 

The most basic support is still 802.11b; and that'll probably be kind of

10mbit is still the most basic ethernet-over-twisted-pair support.
