Windows 10/11 Laptop and MIMO power save mode SMPS settings

Access Points MR56 - only broadcast SSID on 5ghz

Laptops Thinkpad running either AX201 or AX211 chipset running Windows 10/11

Looking in wireless issues we are having, and noticed the settings in driver for SMPS

From my understanding this setting will only use a single antenna on the end point to reduce power consumption.

Anyone disabled this setting and set it to No SMPS so all antennas are active and see improvements in wireless.

Yes, SMPS is designed to save power by using only one antenna at the endpoint. In theory, disabling SMPS ensures that all antennas remain active, which can improve wireless performance.

I've seen some people report improvements in wireless connectivity after disabling SMPS, but to be honest, I've never tried it.

You mentioned that you are experiencing some issues related to Wi-Fi. Have you conducted a site survey? Often the problem is related to poor wireless network design.

@alessandrodematos is exactly right, disabling SMPS can improve client performance, however if there are issues in the wireless deployment, a Site Survey would help to shine a light on any problem areas. You can utilise your Meraki APs to conduct a survey if you do not have one available.

We have had multiple discussions with our Cisco Solutions Engineer and done site survey and applied various changes to improve performance. I am now looking at it from a endpoint perspective rather than the access point.
