Do you mean 802.11g? I had been streaming HD captures from a HDHomeRun
over 802.11g without too much trouble. That was through 2 drywall walls
and was fine as long as the microwave was off and no other computers
were on the network. You are correct though that 22/24mbps is about the
max realistic throughput for 802.11g.<br>
<br>
802.11n is another matter, I just updated my router firmware and now
the 802.11n chipset in it plays nice with my MacBook Pro 802.11n
chipset. I now get real-world speeds that max out around 72mbps, the
router is much more tolerant of the microwave and other computers can
easily be using the network while I stream HD content (~22mbps). My
usable range for HD streaming also increased by ~ 25%.<br>
<br>
I will say that fast-forward over the 802.11g connection wasn't the
best but I really only used the 30second skip forward 5 second skip
back buttons. Now that I'm on 802.11n fastforward/rewind work better
but the skip buttons are still the easiest.<br>

<pre wrap="">This is *exactly* the behavior I saw. And this was with recorded

on the combined FE/BE, so I don't think it's a seek-table issue. I'll
yank the FE out of the bedroom and try it hardwired tonight. Any
metrics I should try and gather at the same time? Anything in
particular I should look for in the log files that might be of use?

If you're trying to stream ATSC HD over 802.11n, stop right there. Don't
pass go, don't collect $200, go straight to jail.
802.11n's real-world throughput is 22 mbps. Yes, the specification says 45
mbps, but there are a bunch of technical details as to why real world you're
going to top out around 22mbps. And that *assumes* that your AP and laptop
are both in the middle of a cornfield. Once you add in neighbors with their
own APs, wireless phones, microwave ovens, and all the other things that can
gunk up the 2.4GHz spectrum, your throughput goes wayyyyyy down.
...then add in that you're trying to push the stream 3x, 5x, etc. faster
than normal via fast forwarding, and it doesn't surprise me that it wouldn't
work well over wireless. (or at least, not 802.11n.)
Besides, do you *really* want to broadcast your porn collection to your
neighbors? (Or worse, do you *want* them to know that you watch Oprah?
:) )
