Re: APs disappearing from network

Your NTP (port UDP 123) traffic is being blocked to the internet somehow.  If the time is incorrect, your APs cannot securely connect to the cloud to obtain their software image, because they thing the certificate is not valid.  Make sure NTP traffic is not being blocked to the internet, and then try rebooting one of the APs with the wrong image and see if it gets the correct time and then the correct image.

Re: APs disappearing from network

You can roll out a new version via SSH by:


IAP#upgrade-image name


image name for 305 should be ArubaInstant_Ursa_6.5.4.3_61959

however i doubt this will work for you, because of the same reason colin suggested.


NTP and internet acces should work first. A rough test will be pinging although NTP is on UDP ports.. But this will test your DNS and internet connectivity.
