Re: MR 25.11 Latest Stable

What exactly is this HSRP support?

Re: MR 25.11 Latest Stable

Hi MerakiDave

   Since the update (25.11) I'm experiencing frequent channel changes with both 2.4 and 5 on models MR 42 and MR66.  Any help on this as clients are dropped for about 45 to 60 seconds when this happens.

 

Thanks for your help

David

Re: MR 25.11 Latest Stable

@dmo What does Wireless Health show? Have you made any recent config changes? 

 

I'd recommend starting a new thread instead of adding to this one.

  • Condition under investigation causes lower than expected throughput on the 2.4GHz radio (MR26/MR34)

That's almost the understatement of the year!

 

Please note that this ALSO applies to the 5Ghz radio on the MR34.

 

The PR-speak "lower than expected" should be updated to reflect reality- "almost unusable" is more approriate.

This is a big issue. May have to roll our entire school district back to 23. Causing lots of issues with state testing. Please come up with a fix soon.

@NetAdmin

 

I've been helping them test a beta firmware for the 2.4Ghz bandwidth issue (3Mb/s... really) and can confirm that they have fixed that issue in that firmware.

 

However, they broke the Staff SSID (password protected, relays to a Windows DHCP) where an access point will randomly not allow a client to get a valid IP address.  They can switch the the Public SSID (open, Meraki DHCP) and function except for critical internal network functions.  They can go to another room and connect fine on the Staff SSID.  The only cure is a reboot of the affected AP.  There is no rhyme or reason. 

 

I think they were able to gather enough info due to my troubleshooting efforts.  It wasn't until last Thursday that I was able to get them on the phone while it happened after school hours here.  Hopefully this issue gets fixed very soon.  So far this week I've been proactively rebooting every AP first thing in the morning and it seems to have helped.  It's a PITA to reboot 50 WAPs though!

If the reboots can get us to the next release I am willing to give it a try. But as you said rebooting all those APs is a PITA

Here's a thread on some ideas to reboot WAPs: https://community.meraki.com/t5/Solutions-APIs/API-Call-to-Reboot-AP/td-p/5863

Re: MR 25.11 Latest Stable

You'll may have to contact support as I am not sure it's in the Beta channel yet. I can tell you that this seems to be the only issue I've seen with performance, so far. This is at a site that ONLY has MR34 devices.

(FWIW- I tested MR42 and MR52 throughput at same site and the MR42 was the fastest on 2.4Ghz band. Go figure)
