Wireless firmware versions MR 31.1.5 changelog

Important note

Wi-Fi 5 Wave 2 MRs support - This version and subsequent MR 31.x.x are only supported on 802.11ax (Wi-Fi 6) and newer MR models. 802.11ac Wave 2 and older products will not upgrade if they are in networks configured for MR 31.x.x versions, and thus, the new features will not be available. The bug fixes listed below will also not apply to Wi-Fi 5 Wave 2 and older MRs. (https://documentation.meraki.com/MR/Other_Topics/Cisco_Meraki_MR_Firmware_Restrictions_Overview_and_...)

The recalcitrant CW9166I AP that won't broadcast on 6GHz is being RMAed as it cannot find the cloud after upgrading to 31.1.5 and then being factory reset... I'll let you know how the replacement gets on, both with 31.1.5 and the 6GHz band...

Had to switch back to 31.1.4 due to CW9166I's frequently (every few minutes) loosing connectivity. 😐

That's what happened to mine, so I performed a factory reset and they wouldn't find the Meraki cloud... New one arriving today... 🤞

New one boot looped the same, so downgraded the network to 31.1.4 but it is still bootlooping. Pulled the patch cable and lets see if that recovers it.

Still bootlooping, out of date config and it thinks it is in the Netherlands (possibly related to the config issue) so downgrading network to 30.7 🤞

Wow, that's a huge bummer!

Looks like 31.1.5 killed the replacement CW9166I and after I reported this to support the release was pulled...
