What's more straight than saying: The team recommends that the only
firmware to be used with the new 2.6.25 kernel is 22.p18 and the only
known issue that this team has characterized so far with this
firmware, that can be of interest to the XS, is timing issues with
WPA? There may be others, but they are not "known bugs" so far.

By the way. Actually, no. Even the WPA issue should not interfere with
the XS. And, I would like to understand what is the connectivity model
that you are trying to implement on the XS. Are we insisting on using
active antennae as mesh gateways on the XS? Is it clear to you that we
do not recommend this at all?

Simply put. The model of having a bunch of school servers with a bunch
of active antennas to support hundreds of laptops in 3 mesh clouds
should be completely abandoned. The recommendation of the connectivity
team is: use access points (note: active antennae will act as APs
shortly, but this is another story). What are your reasons to do
differently?

Again: With the 2.6.25 kernel and older firmwares, you would
experience wireless "crashes". Other than that (i.e. previous kernel
with recommended firmware),  no one has reported any "overnight reset"
with the wireless firmware for months.

Firmware 20.p49 is deprecated for months now. I had no idea that
someone was using it (a communication flaw?), and I don't recall
reading any questions on what version should be used with the school
server, before now. Have this question been asked?
