Thanks for the prompt response! Yeah, was hoping for a usable on-board wifi option. I have a good AC Router (TP Link) as sidestepped my provider's ActionTec -- which isn't terrible, but it's not terribly good, either. ;-)
I can add a local router in bridge mode, then. A little more cumbersome, but not a show-stopper. There are, of course, other options as well, all more expensive that what the wireless adapter might have been, but I can make it work. The Mede8er has been such a rock solid 1080p media player that it's worth breathing some life into extending its use on a secondary TV. Plays well with my Plex/Plex Open Home Theatre library, too, so I'm pretty well vested in keeping it around.
Thanks again for the response.. and, I have to say, it's pretty amazing to see this community still active and posting. Most products this age would have dead forums by now, imo and general experience.
Best Regards
