Meraki firmware upgrade to MR 31.1.5.1

[Sachin-Bhatgare]

Dear All,

I have MR36 and MR86 access points with firmware version MR 30.7.1. I have observed that clients utilizing WiFi 5 are experiencing reduced link speeds, an issue that appears to have arisen following the firmware upgrade to MR 30.7.1.

Could you please advise if it is advisable to upgrade my devices to firmware version MR 31.1.5.1? Additionally, will this upgrade potentially resolve the issues I am encountering?

Thank you for your assistance.

The best way to test (IMO) is to select a couple of APs in your environment have support lock them in on 31.1.5.1 and see what the experience is like for your users.

There are multiple correct answers.

If it was me, I would back the firmware to the last version that worked correctly.

I tried upgrade on one of the networks and it was successful. Thank you all.

The firmware upgrade was successful, but I am still getting the link speed at around 96 Mbps on MR86. With MR36 it's around 400 Mbps. Please reply if you know the solution/workaround.

I encountered a similar issue when provisioning new networks that received firmware version 31.1.5.1 on the MR57 access points.

The primary complaint was significantly reduced speeds, averaging between 8-90 Mbps. Upon examining the AP device health, I noticed that both CPU and memory usage were extremely high. After consulting with TAC and downgrading to firmware version 30.6, the performance returned to normal.
