Plex on OSx is giving me strange error

Hey all…

I’m having a terrible time trying to play anything on my OSX (MacbookAir)…

It repeatedly comes up with…
“Not enough bandwidth for any playback of this item. Required minimum bandwidth is 103kbps and only 64kbps is available”

The “Plex Media Player.app” sees all ok, and can manage (create libraries, etc), ok.

I am wireless, but test of file copies show 10-15Mbps, so it’s crazy I’m getting this message.

I tried to find an OSX player section under players in this forum, but can’t see one, am i blind??

I’m running PlexMediaPlayer-1.2.5.606-0b42eb77-macosx-x86_64.zip version.

Doubt it matters, but my server is on Synology DS412+ NAS. Upgraded to latest today.

It plays to my Android phone ok.

might also add that it plays on my AppleTV 4th edition fine.
(so the server on NAS is ok)
