Hi,
my first problem is now resolved. The ports were in different VLANS.
Now my next Problem is, the 2 new IAP don`t join the exists Wifi ?? Why ??
When i connect the 2 IAP to the switch port, my whole wifi connection will be interrupted.
and i don`t have any connection to the VC.
When i disconnect the 2 new IAP, my Wifi and all AP are UP und runnfig fine.
I don`t know what happen in the background.
regards
Salvatore
