MR 29.3 Beta Out

Getting noticed

MR 29.3 Beta Out

General Fixes and it appears some rather specific bugs fixed.

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 on firewalls that are deployed upstream of your Meraki APs. (Wi-Fi 6 and Wi-Fi 6E APs)

Legacy product notice

  • When configured for this version MR12, MR16, MR18, MR24, MR26, MR32, MR34, MR62, MR66, and MR72 will run MR 26.8.3.

Bug fixes

  • General stability and performance improvements
  • Disallow RF mode switching for CM64 boards
  • Intermittent low power mode (MR53, MR56)
  • SES-imagotag bootloop (MR30H, MR33)
  • Honeywell printers unable to connect to hidden SSID

Known issues

  • Sporadic packet loss & instability on Layer 3 roaming & Teleworker VPN SSID's (Wi-Fi 5 Wave 2 and Wi-Fi 6 APs)
  • No DHCP response error is seen after a client performs a successful L3 roam (Wi-Fi 5 Wave 2 and Wi-Fi 6 APs)
Kind of a big deal
Kind of a big deal

It seems to be stable on an MR55/56 mixed network

Kind of a big deal

Same here on a mixed MR36/45/46 network.

Comes here often

we were experiencing same performance issues.

MR56 speed degrades over time but after restarting AP, speed restores to max.

raised case with Meraki/advised to upgrade to 29.3 BETA. 


under observation now since few hours and stable.


any idea when 29.3 STABLE release will be out ?
