"Max retransmission count" error connecting Cisco APs to WLC
Posted on 2016-10-05
We have a number of Cisco AIR-CAP1702I-E-K9 APs and a virtual WLC (v8.0.140). Four of the APs talk to the WLC ok, but the remaining two won't connect with the following error:
One of them was working previously but had a factory reset; the other is out of the box. How can we make them connect to the WLC to be managed?
Oct 5 15:48:06.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.50.50.119 peer_port: 5246

Hmm... looks like some patience is required. They connect nevertheless after many minutes.

Just posted in the other question, but yes, it looks like the APs are struggling to talk to the WLC reliably.

It looks like I just needed some patience; I've got them all connected now and their IPs set to static. Thanks.

Different problem now so have asked new question: no wireless output from the APs despite WLAN and groups being set up. Must be something simple somewhere...? Thanks.
