EAP-110 Outdoor AP not retaining configuration on auto nightly reboot
We are currently using 7 EAP-115 and 1 EAP-110 outdoor APs in our apartment society gates for Wifi Access to MyGate Tablets. Recently we have observed a niggling problem with the EAP-110 outdoor unit that after reboot it does not ratain has its configuration and has to be manually adopted and WLAN group reconfigured. Here is the controller log:
(1) All our APs are configured to restart at 4:00 am in the morning everyday,
(2) The Outdoor AP (70-4F-57-74-40-B2) also follows this routine but when it restarts it does not come back to its configured state like other indoor APs (EAP-115s with macs ending with F2, F8, 4B octets in picture), despite controller being kept on. It just goes into Pending state with the correct IP and connectivity (layer 3 networking sems just fine because it is able to get on the network)..
(3) To bring out of its pending state, we have to
(a) manually adopt the AP
(b) assign it to the correct site and configure the WLAN Group on the AP again
(4) After this the problem goes away for a day or 2 or 3, till it reappears.
This has started happening after we switched from Auranet Controller to latest Omada Controller (now running 3.0.5) OR one of the Omada Controller software upgrades. It was defintely not observed for 6-8 months of operation with the Auranet Controller
Any pointers to debug further or resolve will be appreciated.
