What happens if a network loses connectivity to the Meraki cloud?

Because of Meraki's out of band architecture, most end users are not affected if Meraki wireless APs, switches, or security appliances cannot

communicate with Meraki's cloud services (e.g., because of a temporary WAN failure):

* Users can access the local network (printers, file shares, etc.)

* If WAN connectivity is available, users can access the Internet

* Network policies (firewall rules, QoS, etc.) continue to be enforced

* Users can authenticate via 802.1X/RADIUS and can roam wirelessly between access points

* Users can initiate and renew DHCP leases

* Established VPN tunnels continue to operate

* Local configuration tools are available (e.g., device IP configuration

There will be a throughput reduction (~50% reduction) with each ''hop'' in a mesh. It is recommended that a mesh network be designed for no more than one mesh hop from the gateway to client device.

The number of devices in an organization can not exceed the license limits. If this occurs, the organization will enter a 30-day grace period, during which the organization must be brought back into compliance, otherwise it will be shut down until proper licensing is applied to the organization. https://documentation.meraki.com/General_Administration/Licensing/Meraki_Co-Termination_Licensing_Overview

When band steering is enabled on an SSID, APs will stop advertising that SSID in 2.4GHz beacons. Since 2.4GHz-only clients that rely on a passive scan will not ''see'' that SSID in beacons, they might not be able to join this SSID unless they do an active scan or have been pre-configured with the SSID name and security settings (for example, a pre-shared key). https://documentation.meraki.com/MR/Radio_Settings/Band_Steering

This is the approximate number of APs that are needed based on client count, assuming that each AP can support up to 25 concurrent video streaming users. This can be calculated by using the formula:

Number of APs = (Number of Users x Percentage of Users on a Band) / Number of Users per AP on that Band

Where Number of Users is 100, Percentage of Users on 2.4 Ghz is 30%, Percentage of Users on 5 Ghz is 70%, Number of Users per AP on 2.4 Ghz is 15, and Number of Users per AP on 5 Ghz is 30. Therefore,

Number of APs = (100 x 0.3 / 15) + (100 x 0.7 / 30) Number of APs = (3.33) + (2.33) Number of APs = 5.66

Rounding to the nearest whole number, the number of APs is4.
