New Wireless RC 31.1.6 - Lots of Fixes

[Mloraditch]

Lots of Bug Fixes, several having to do with Radius that sound suspiciously like random forum posts I've seen!

EDIT: "Sporadic packet loss & instability on Layer 3 roaming & Teleworker VPN SSID's (Wi-Fi 6, Wi-Fi 6E APs)" was moved to fixes by Meraki after the original post. Very very long outstanding bug that may finally be fixed.

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 only 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_...)
• Includes support for Wi-Fi7 APs (https://documentation.meraki.com/MR/MR_Overview_and_Specifications/CW9176I_%2F%2F_CW9176D1_Datasheet, https://documentation.meraki.com/MR/MR_Overview_and_Specifications/CW9178_Datasheet)

Bug fixes

• General stability and performance improvements

• MR57 ethernet port flaps occur when connected to MS355 at 5Gbps speeds
• MR46 not responding to Probe Requests from clients
• Channel & power not configurable via LSP on CW9163E APs
• Wildcard NAS-IPv6-Address AVP sent on config change (Wi-Fi 6, Wi-Fi 6E APs)
• NAS-IP-Address discarded (Wi-Fi 6, Wi-Fi 6E APs)
• RADSec authentication failures (Wi-Fi 6, Wi-Fi 6E APs)

Most important part : 802.11ac Wave 2 and older products will only upgrade to the backup version (MR 30.7.1)

😍

Exactly ( ↖️ ) 🎉

@cmrin shambles after being beaten to the release notes post 😏

[cmr]

Just sharing the love @Paccers 👍

For me the 'Sporadic packet loss & instability on Layer 3 roaming & Teleworker VPN SSID's (Wi-Fi 6, Wi-Fi 6E APs)' item is listed under 'Bug Fixes' section

[RaphaelL]

Same here but I swear it was listed as a known issue. Might be a corrected typo

[Mloraditch]

Yes i see that now too. I definitely just copied and pasted so they must have edited. Crazy if that's finally fixed

[meraki-chris]

Yes, that was a correction - moved to bug fixes

[RWelch]

@meraki-chris 👏 👏 👏 🎉

I perfromed a rollback on my MR36H to MR 30.7.1. As posted already with MR 31.1.5.x, I also experience lags with MR 31.1.6 during longer Webex Calls (>30 minutes) and other usage like streams or "high" bandwidth and low latency connections. After 50 minutes call today, I even got a short loss of connectivity. With MR 30.7.1, at least with my MR36H in use, I have no issues. Someone else epxerience lags with MR36(H) and MR 31.x?

Were you able to get anywhere with support?  I just upgraded a site to 31.1.5.1 2 weeks ago and been having issues, and was planning on upgraded to 31.1.6 but seems like I might be better off just going back to 30.7.1

Site has a mixture of MR42/MR46E/MR44. Since the upgrade the site has been complaining (everywhere) about slow connections, random disconnects, trouble connecting.

I only posted my question in this forum. I did not raise a support request. But no update to my question in the community post yet.

I downgraded to 30.7.1 and have no issues with the MR36H. With 31.1.6 or the earlier 31.1.5.x release I have had the issues you described, too.

This was promoted to Stable as of yesterday (15 days!), record time for Stable RC to Stable move?
