Kind of a big deal

New

  • Initial stable firmware for MR36/MR46/MR56
  • Client association syslog messages now use the verbiage "last_known_client_ip" for association and WPA authentication messages to better represent the IP being reported (All MRs)

Bug fixes

  • Air Marshal considered VAP (SSID) numbers 5-14 as non-Meraki and would report as spoofs or contain BSSID based on Air Marshal configuration (MR45/MR55)
  • 802.11ax information elements broadcasted after disabling in RF Profiles (MR45/MR55)
  • Incorrect WMM parameters (ECWmin/max, CWmin/max, TXOP) after 802.11 PHY mode change (802.11ac Wave 2 MRs)
  • Invalid memory reference leading to reboot for mesh repeater (802.11n MRs)
  • MR was no longer sending ARP probes to check for passive client associations (All MRs)
  • SSIDs configured with Umbrella integration did exclude domains configured exclusion if DNS query was TCP (All MRs)
  • Walled garden domains not updating for SSIDs configured with Umbrella Integration (802.11ac Wave 2 / 802.11ax MRs)
  • Mesh repeaters flooded DHCP Discovers when Client Isolation was enabled (All MRs)

  • SSIDs matching a blacklist policy were not contained if the blacklisted SSID used a non-ASCII character (All MRs)
  • Default RX-SOP configuration could contribute to degraded 2.4 GHz performance as compared to MR24.x firmware (MR42/MR52/MR53/MR84)
  • DFS event detection was overly sensitive (MR42/MR42E/MR52/MR53/MR53E/MR84)
  • Wireless Health Latency only displayed Best Effort traffic (802.11ac Wave 2 MRs)
  • Channel utilization graph on the "RF" tab of the Access Point details page did not populate data reliably (802.11ac Wave 2 MRs)
