I am seeing 20mbps BOTH WAYS on the older 266 boards.  I also have a stack
of 400mhz boards here, got them from WISP-ROUTER a while back for a project
I was doing.   Just a FYI on the last question.

On the speed, I am speaking of the Ethernet, I am also getting one way
speeds in excess of 90mbit doing FTP transfers one-way.  This is just
eithernet to ethernet not wireless at all.  It would show that the 532 board
is capable of doing more via ethernet, than wirelesss if this is the case.
I will be getting some new wifi cards, to check out and see what the speeds
are though them in a test lab, will let you know!  Just a FYI, I do have a 5
mile, 5 gig link now that does 25 meg on-way using 532s, it is nstream, but
not dual radios/antennas.

But it is important that we define "both ways",  expecially when dealing
with Wireless cards.

The max data we've been able to get out of a Mikrotik 532 AP, with 20Mhz
channel 5.8G, connection tracking off, no type of compression considered,
is
about 20mbps thoughput.  That means 20mbps in the Ethernet and 20mbps out
the wireless card or Vice versa.  It Does NOT mean 20mbps Full Duplex over
the wireless.
The big advantage that StarOS had over Mikrotik was the ability to run on
a
533Mhz board allowing Wireless speeds as high as 35-40mbps without
compression on a single 20mhz channel.  Mikrotik 266Mhz boards in my
opinion
are wasteful to Wifi, if using 20Mhz channels, because the bottle neck is
the CPU not the Wifi Card.

With that said, I saw the press release on the Mikrotik 400Mhz 532 board,
however, I have yet to see one sold any where.
Are these available yet? Are they just 532 boards being overclocked? Are
they stable?
