I half win. The toshiba bluray player (BDK23) is wireless "ready," which I figured by the big ol' WIRELESS READY on the front of the box meant it'd work just fine over my g-network after I put the mac address into the router.
Nope! After trial and error (trial being wondering why wireless network discovery didn't work and error being the whole unit freezing up when connected to the switch closest to it as opposed to working fine when connected directly to my router) I found out via the online FAQ that if I want to use wifi with it I have to purchase a proprietary usb wireless adapter from the toshiba direct website.... which doesn't sell it. Other places have it for $50-70. There's only 1 usb port, which is on the front of the system, so to use wifi I'd have to give up bd-live features that need a usb flash drive to run.
Also, for some reason until I actually PLAYED a bluray disc, the tray would stay open whenever I turned on the system. and THEN it wouldn't play anything (I tested on the avengers) until about the 3rd or 4th time I ejected and then loaded the disc.
Cost-cutting at it's finest. To it's credit, once it was online it got the latest update and rebooted just fine. And now it acts like it's supposed to and plays back content wonderfully. I contribute my problems to simple derps and first-time running of the unit. Still worth the cost, though. $40 hell yeah.
