Stable release candidate MR 28.6 released today. Discussed with support and this specific bug wasn't mentioned in the changelog which annoys me. They assured me it was fixed. I just updated 201 AP's in my High School. Wireless firmware versions MR 28.6 changelog Important note Meraki APs use UDP port 7351 for cloud communication and TCP ports 80 and 443 for backup communications when running MR 27 and older firmware. When running MR 28 firmware, Meraki APs will now use TCP port 443 as the primary means for cloud connectivity. In order to maintain connectivity to the Meraki cloud on MR 28+ ensure that TCP port 443 is allowed to communicate with 209.206.48.0/20 on firewalls that are deployed upstream of your Meraki APs.
