We manage via airwave a customer site with 16 215 IAPs. Since OS 4.3.1 they have issues with roaming on 2.4ghz. Especially 2 android devices. It takes a long time to have a connection again. We have enabled client match, done proper channel planning on 2.4ghz en reduces radio signal strength.
Btw at another customers site they have trouble in a warehouse on 2.4ghz woth honeywell handguns.
In Airwave we can not find proper information what is going wrong with apecific clients - only globalnissies like too many frame errors for example.
Any can help or point into good direction?
