Cisco Meraki access points can operate in two functional modes for meshing purposes: gateway and repeater mode. All MR access points are capable of functioning as either a gateway or a repeater in a mesh network. This article outlines key differences and behaviors of gateway and repeater access points.
A Cisco Meraki gateway is an AP that is physically connected to the LAN. It has a direct route to the internet and local resources over its wired connection. It holds a valid IP address, subnet mask, gateway IP and DNS servers.
A Repeater AP does not have a wired path to the Network. It meshes to other MR units, repeaters or Gateways in order to pass traffic out to the local LAN, Internet and Cloud Controller. A Repeater AP will never hold an IP address and requires at least one MR gateway within the wireless infrastructure to route traffic out properly.
Some additional information on the RF page includes:
Avg Mbps - shows the speed of traffic moving over that specific route.
Avg Metric - a calculation based on signal strength, speed of wireless channel and distance, a metric value under 2000 is optimal.
Usage - information about how often that specific route is used, a repeater AP can have multiple routes

Self-healing technology in Cisco Meraki APs allows them to automatically reconfigure and use mesh links in the event of a wired Ethernet or switch failure, forwarding traffic to other APs in the network that have Internet gateway connectivity. APs establish mesh networks automatically, even when connected to the wired LAN, making the optimized mesh link immediately available in the case of a wired LAN failure event.
APs maintain a per-flow track of traffic, so clients already associated to an AP continue to have connectivity and experience no interruption in service. Cisco Meraki mesh technologies, including automatic link optimization, adaptive capacity management, and failure resilience enable networks to continue operating despite failures or configuration changes in the rest of the network, without the need for manual configuration or optimization.
