Looking for 5760 QoS configuration example to solve 7925 phone connection problems

[Heiko Kelling]

Hello,

we still have problems to connect 7925 phones with a 5760 controller. First we had suspected, the channel allocation because the controller had 8 of 12 APs with the same channel config. Now we use only a-standard with manual channel config but the phone says: "connection failed" and "leaving service area".

The last hope is a good QoS config for 5760 controller. Can anyone recommend a good qos config.

May be the qos config so important that a phone can not connect without it? Our wireless network is not in use by nobody so far.

Thanks in advance.

Hello,

the reason was the QoS config. Now everything works well with this config:
