I think all APs do multicasts over WiFi as unicasts to every client.
WiFi could, I guess, in theory do true multicasting, but since it's all
acknowledged at the radio level, and encryption and what not, WiFi do it
all by unicasts. But that is basically hidden away, and usually works fine.
Much worse is that with DECnet you want to change the MAC address, which
WiFi gets really messed up with, and it usually do not work well at all.
And that especially gets messed up when in combination with the
multicasting.
I didn't know that IS-IS had problems over WiFi. I learned something new
today. Cool. Thanks.

Ethernet multicast

(This is the same problem as running IS-IS in your home network...)

Indeed, for Phase IV and IV-plus. Fixed
(obscurely) in IV-prime, and in Phase
V.
Some day I should implement IV-prime in PyDECnet. It's not all that hard.
If you just want to use WiFi to run IP based tunnel type protocols, there is no
issue. And if the router you're going to doesn't restrict the remote IP
address for its traffic (in PyDECnet, you can only do that for TCP based
protocols: Multinet and DDCMP) then you should be able to do "ad-hoc"
connections just fine.
