Just signed up for the android beta and got the latest build - can confirm that it resolves the WiFi syncing issue. There's also a thread about this issue in the beta forum. Thanks!

There is known issue that windows firewall blocks MMA accessing MMW server even MMW correctly added exceptions

Do any UPNP apps on Android see MMW DLNA server?

Did you update to the latest betas of both MMA (subscribe to beta program) and MMW (from Beta forum)?

I'm having the same issue, after updating to N my WiFi syncing no longer works.

I'm having this problem as well. But on top of that, synchronizing doesn't work at all. Just updated to Android 7 on a Nexus6p.
MMW will say Preparing List of Files, and then it freezes on its first transfer.

Has anyone gotten WiFi syncing to work on the "final" release of Android N? USB syncing works fine for me, but WiFi won't find any MMW server.
