An alert may appear on your AP detail page stating: "This device is having difficulty contacting the Meraki Cloud. Please make sure your wired network allows outgoing connections to x.x.x.x and x.x.x.x on ports 443, 7734, 7351 and 7752." When this happens, the AP icon (located in Dashboard under Wireless > Monitor > Access Points) turns yellow, the connectivity graph is green, and the AP does not download the latest firmware or configuration from the Meraki Cloud.
The MR12 and MR58 wireless access points have two Ethernet ports that can be used to connect the device to a wired network. However, a static IP can only be set on the primary Ethernet interface.
Wireless packet captures are incredibly useful while troubleshooting specific events on a WLAN. The most common use is to see all communication (data, management and control frames) between a station (STA) and an access point (AP). This is easily possible while using an AirPCAP adapter however these can be expensive and may not be available while experiencing connectivity issues.
A device may appear on the Event Log but not be visible in the clients list. Searching the clients list will also not return this entry. This occurs when a device attempts to connect to an SSID but is not able to fully connect. If you click on the device in the Event Log there is a page for that device but the traffic graph and pie charts will be blank
Alert messages can be viewed by clicking on the AP in question located under Monitor > Access Points. These messages can be used to aid troubleshooting what issue an AP may be experiencing. Cisco Meraki devices attempt to connect to Dashboard in a variety of ways to allow you to troubleshoot connectivity issues even if some network services, like DNS, are not working. This article will discuss the various alert messages that may appear in Dashboard.
When monitoring your wireless environment, the event log (in the Dashboard at Monitor > Event log) can be an invaluable tool in gaining a additional visibility into current activity. A list of the common wireless event log messages along with their origin and their potential causes can help to bring a better understanding of the wireless environment.
When Bridge mode is enabled, wireless and wired clients connected to your Meraki APs will receive an IP address from the DHCP server on the wired LAN. If your DHCP server is unreachable, misconfigured, or has no available IP addresses left in its DHCP address pool, clients will not be able to receive a DHCP lease and the following message will appear in the Meraki Event log
Hostname Visibility is a Traffic Analytics feature. Enabling Hostname Visibility will allow you to view statistics about specific hostnames and IP addresses that are visited by clients on your network. You can view these statistics for your entire network and per-client. This type of information can be useful for understanding the types of traffic flowing over your network and constructing traffic policies to meet the needs of your Organization.
The Meraki MR34 and MR42 access points require 802.3at power to provide full functionality. Some switches and POE injectors are not capable of supplying this level of power. If the MR is receiving less power than the 802.3at standard, it will display "running in low power mode".
Cisco Meraki access points with a dedicated WIPS (Air Marshal) radio, such as the MR18 or MR34, have the ability to do real-time spectrum analysis of their environment while still serving clients. This information can be useful when troubleshooting wireless issues or determining which channels to use in high-density environments.
Access points can use either dynamic or static network connection information. Though DHCP is recommended, you may configure a static IP address on a Cisco Meraki AP from Dashboard or locally.
The Cisco Meraki Dashboard has the ability to list the real-time channel utilization detected by a particular access point. This is helpful to understand the performance and stability of the RF environment. The real-time channel utilization can be viewed on the dashboard under AP details.
Live tools on the Monitor > Access Points page can provide important information and assist with troubleshooting . To use Live Tools, select the access point of interest from the Monitor > Access points page. This article is an overview of the available services associated with this feature.
Wireless clients can show up on the AP details page as a currently connected client, and the client details page will show network usage. However, a wireless client will not show up under Monitor -> Clients until they generate some amount of Internet traffic.As such, it is common for wireless printers to not show as a client connected to the AP, if it only provides LAN-based print services.
MR access points (APs) have the ability to monitor client network traffic, to help identify and narrow down potential network problems. When configuring access points (APs) to use VLAN tagging or RADIUS servers, additional status fields will become visible on the AP details page. These status fields can be used to help identify potential problems relating to RADIUS authentication or a particular VLAN.
