[CUWiN-Dev] Cisco cards

Hi
I have a question about wireless card compatibility. The CUWiN
documentation says that Aironet/Cisco chipsets have problems working
with the network:
"...just one Hermes chipset mixed in with other nodes can cause a
serious network split. Firmware upgrades do not appear to completely
solve this problem. Aironet/Cisco chipsets have the same problem."

But in regard to the Atheros chipset, the documentation says that: "This
is the chipset currently recommended by the CUWiN team. Most tri-mode
a/b/g cards on the market use the Atheros chipset." I'm hoping that it's
only the older 802.11b-only Cisco cards that are problematic and not the
newer a/b/g ones, since I think those do in fact use the Atheros
chipset, e.g., see: http://www.networkinstruments.com/support/osup1049.html
So are the Cisco a/b/g cards among those recommended?

By the way, my understanding from one of the MIT Roofnet developers is
that in regard to loss of throughput at each hop: "We're also
experimented with 54mbit 802.11g radios and found they actually do worse
than the 11b radios. "

Do you have similar experience in regard to that? About how many nodes
are in the largest current CUWiN installation? And what's the most
number of hops you see on a regular basis from any nodes?

      Thanks,
