Hi Edgar, I have one simple question.

802.11w had a vulnerability a while back and the button was greyed out so it couldn't be enabled. Now that the button is back, is it safe to enable 802.11w?

Hello @cjjones 

I don't have recent information regarding vulnerabilities involving 802.11w (Protected Management Frames). if you have details for it, feel free to share and I can dig more into it.

Recent major vulnerability for wireless, known as KRACK vulnerability was referred to the use of 802.11r (Fast transition). For this particular vulnerability, the fix was implemented since the firmware version 25.7. The latest stable release is 25.13, and it is safe to use 802.11r over the fixed firmware.

Need to know how data fulled from cloud to miraki devices?

[edmonroy]

Hello @BharathPatil6936 

The communication between the Meraki Devices and the Meraki cloud is done via a secure encrypted connection across the internet. Current public subnets for the Meraki cloud servers are 64.62.142.12/32, 108.161.147.0/24, 199.231.78.0/24, 209.206.48.0/20. Communication uses UDP port 7351.

Meraki hardware devices act as the server/receiver as the Meraki cloud initiates calls to the devices for data collection and configuration deployment.
