Hello ,
I have problem with AP 1262 witch periodically lose his connection to the controller.
I have this situatuion. One WLC 5508 and two 1242 dual band controller based APs.One AP 1242 is connected to the controller through fiber link.The other AP1242 is connected to WLC through first AP on 5GHz Wireless Backhaul.First one is RootAP and second one is MeshAP.WIreless link between two APs have SNR=40dB and distance is no more than 30 metres(100 feet).Antennas used in this case is directioanl 5GHz "AIR-ANT5160NP-R" with gain 6dBi.
MeshAP have an IP and have alreaday downloaded IOS image and configuration from WLC. MeshAP is working fine when he si connected with WLC , and client can gain access two WLAN.
However the MeshAP is periodically dropping his connection to WLC.(once every 4-5 hours).
This is part of the log generated by the WLC before loosing connection with MeshAP:
