Even the corrected URL (.com) does not. It refers to a home page with
no apparent links to a speed test.

Yes.

Full-duplex should help then there are more than 2 machines using the
network.

They claim 11Mbps. People often don't notice the "UP TO".
Wireless adds a lot of overhead.
Range will be significantly less than advertised.

With my 5xxx, the file sizes are about 880MB/hr for Medium and
1.6GB/hr for Medium. What do you get?

I do streaming between 2 Replays (both 5xxx) a lot, but have a good
wired connection through 1 ethernet switch. High worked (but made the
units sluggish) when I tried it (but that was just a test, there seems
to never be a need to actually use High).

And the limitation would be your broadband UPLOAD speed, which is
likely to be a lot less than the download speed people talk about
more.
The difference in download and upload speeds is one reason why I use
newsgroups when I need a certain show. My cable internet is 1024kbps
down/128 kbps up (and you can actually get most of that).
