Yes, the Move is S2 compatible - note however the Move will connect to your routers WiFi signal rather than the SonosNet signal - but that (hopefully) should not make any difference as I have had the Move installed in a similar setup in the past. None of the portable Sonos products, nor the latest Era-100/200 speakers use wireless SonosNet.

thanks for your kind and swift reply.  Based on your comments I am now thinking I can eliminate the Boost device from my system.  Your thoughts?

Yes, it will do not harm to try that and run all on your local routers WiFi signal instead. I currently run all my Sonos products on the routers WiFi (with no devices wired to the LAN).

Just use either fixed channel 1, 6 or 11 for the routers 2.4Ghz band, as those three channels are non-overlapping and less likely to suffer WiFi interference. See these two links too:
