Dect 8262/AP400+G7A

[alcanoob]

HI,

I have a problem with my dect system. When i turn on the dect phone, the display says: "Out Of Radio Range" and the phone will not register.
If i reboot the AP`s i get "normal radio signal", and the phone sometimes register.
As you can see its kinda unstable..

I am using OS 6450 Switches, multicast enabled on the vlan used.
Dap manager version:INT 6.21.0163
