Hi,
I have a WLC5508 with around 70 AP's (LAP1042N) connecting over an MPLS WAN network.
WLC and AP's are running 7.4.100
From time to time I have an AP which disassociates from the WLC with the logging beneath.
Can anybody tell me if this is a problem with the AP, or is this due to network saturation between the AP and the WLC ?
And if so, should I change the default retransmit values ?
Thanks a lot !
