I never did get an answer on how the particular Auto Fallback options impact performance or exactly how they work.
Could one of the SB techs chip in on this please? If you have client radios set to Auto Fallback, but you do not set Auto Fallback on the AP, what is the impact? If you have Auto Fallback set on the AP, but not on the clients, what is the impact?

Fallback can be nice to have if you start to see problems with a client or the AP. But should normally not be needed. But say you have a install with poor LOS the tress got leaves on them and it rains and they get wet. Now your signal start deteriorate very quickly. Your client is locked at 11Mbit and he lost say 8dB signal and he is not doing just 1-2dB below 11Mbit limit the wind blows a little moving the antennas and trees causing temporarly drops 1-2dB and the client starts to "chop" he start to see lot of package drops and his connection feels slower then a dailup connection. If autofallback had been on his radio could dropped down to 5.5Mbit and things would worked fine. Another thing If you don't allow autofallback then the client can only speak when the AP is in the right speed. So if a 1Mbit client lock up the AP with a lot of traffic the 11Mbit client just have to wait can't send a single package until the AP is yet doing 11Mbit (I might be a bit off here but this is my understanding). One thing though is that I heard from numerous source that say that many radios seems to autofall back way to fast way to easily which means clients that could run with a steady 11Mbit signal but are at the fringes gets dropped to 5.5Mbit or maybe 1Mbit and it will take some time before it goes back to 11Mbit speeds again. By preventing autofallback you get a more stable and faster network.. Decision decisions.. Actually not so much.. Just be sure to do good installs. Weather seal the snoot out of your connectors and install with good LOS and have a decent (10-15dB) fade margin (SOM) and you should have minimal problems. TB> I can definitely see the major advantage of running everything TB> at the highest Mbs would the ability of the AP to support more clients TB> because it can get each transaction done faster. Absolutely. When you run a mix of clients in different speeds it's easy to lose a lot of throughput on your network because of the slower clients. It's not so much a problem when there is little traffic and/or a few clients. But when you have a decent amount of clients and large amount of traffic then you will quickly start to notice it. I had for example on one of my segments a client that had so crappy signal that I could only get a 1Mbit throughput.. One different client (actually myself at home) had a 3Mbit signal (this is a Alvarion BAII FHSS segment but same goes there as with DSSS). When the 1Mbit client was online (a heavy gamer) and played his online games (EverQuest) my downloads was <100kbit when I normally could hit >150kbit when he wasn't online. He didn't create a lot of traffic nor a lot of pacakges just his steady stream of traffic became noticable. When I got him to be able to do 3Mbit signal things where ones again good. He would be playing and I got >150kbit downloads. TB> Thanks in advance for any enlightenment you can share. I might be a sales guy. But in heart I'm a geek.
