Wireless firmware versions MR 29.7 changelog

Important note

• While Meraki APs have traditionally relied on UDP port 7351 for cloud communication, and TCP ports 80 and 443 for backup communications, with MR 28+ we are beginning the transition to using TCP port 443 as the primary means for cloud connectivity. In order to ensure proper connectivity to the Meraki cloud after this upgrade, please ensure that all “Meraki cloud communication” traffic specified in the "Help" > "Firewall Info" page is allowed through any firewalls or security devices that are deployed upstream of your Meraki APs. These requirements have been updated in November of 2022, so it is important that you review them. (Wi-Fi 6 and Wi-Fi 6E APs)
