" that's addressing the strange SM not reachable issue "
Ok I'm confused . The wording there appears to be talking about the problem where the SM loses network connectivity, becomes unreachable, but return to working if you force them to reconnect (boot them off the AP) or reboot the AP. However the link goes to is posts about the AP's becoming unreachable/crashing and requiring a reboot.
So are these two problems considered the same ? We never had a problem with the APs becoming unreachable or crashing but have had to downgrade all our APs to 2.3.4 (could probably use 2.4.# but haven't tried it) because random SM's will suddenly stop passing traffic and become unreachable. At first we was just rebooting the affected AP but after posting here about it we discovered we could just kick the radio and it would work fine when it came back up.
If they are different problems does anyone know if the unreachable SM problem is fixed in this release ?
