Now this thread has 20 msgs already, and I have a release to work towards. Straight answers please...? 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? - There is an old issue (seen with the 20.49p firmware and oldish driver) with the device getting locked up, which gets solved power-cycling the libertas device. Is it fixed in recent drivers / firmwares? Which ones? Many things have changed since 20.p49 I am sure they have. Now, from the team that has been working on libertas day in and day out for the last N months... does it still reset overnight? Yes, no, dunno? 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.
