Wireless firmware versions MR 31.1.7 changelog - Stable release candidate

[RaphaelL]

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 upgrade to the backup version (MR 30.7.1) 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_...)

Bug fixes

• General stability and performance improvements
• False positive DFS alerts in Japan on MR56 APs
• APs stop transmitting on wired interfaces (Wi-Fi 6 APs)
• Clients disconnect with error code 17 (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• Clients disconnect with reason code 0 (reserved) (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• Association ID mismatch (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• 2.4GHz 802.11n clients unable to connect (Wi-Fi 7 APs)

"APs stop transmitting on wired interfaces (Wi-Fi 6 APs)" yeee that's a slight problem there!

[cmr]

I think I've been suffering from this one:

• Association ID mismatch (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)

Also no known issues...?

[cmr]

I've upgraded a network with CW9166I, CW9163E and MR55 APs, devices have all reconnected, let's see how it goes!

• APs stop transmitting on wired interfaces (Wi-Fi 6 APs)

what does that actually mean ?

[dclay]

Yes, it would be nice if this could be elaborated on. I'm having issues with sporadic latency and I'm wondering if this is the root cause. 

[stgonzo]

Has anyone got this in a network with CW9176 APs, any issues with the firmware

Thanks

[stgonzo]

Version 31.1.7 has gone stable now, so I will upgrade some APs to test

[DEllerbrock]

Hopefully this fixes the GUestWifi Splash page issues?

[serialflush]

I just updated my APs from 30.6 to 31.1.7 and I'm having issues while trying to reach the guest portal from any client

[mhurley131]

I have seen the same in two different deployments running 31.1.7. Splash page issues using Clearpass, as well as the built in splash page. Is this a known issue?

[APGZach]

Been having issues with some legacy scan gun devices on a PSK network. Lots of DHCP issues and association issues. Rolling back to 30.7.1 seemed to resolve.

Hi...I just want to make sure I understand the implications of the above correctly. Does this mean that if I have MR42 and MR53 APs in my environment, they cannot be upgraded to MR 31.x.x?

And is it fair to say the last possible firmware version available to MR42 and MR53 will be MR 30.7.1?

[cmr]

Yes that's about the sum of it, though there may still be security bugfix releases.

[enigma27]

Thanks for confirming.

[r2kat]

But if i am right the access points are still showing the current firmware?
For example i have some networks with MR52 and MR42 and there the current firmware is MR 31.1.6 according to the information panel on the left side. But in truth it stays on MR 30.7.1?

[cmr]

@r2kat yes that's right, it will show the latest firmware that you have chosen, but will actually be running the linked legacy firmware (currently 30.7.1).
