Understanding Alerts

Overview

Alerts are extremely helpful in troubleshooting. They often contain valuable information that is key to resolving a problem. Below is a list of the most common alerts or error messages shown in the Meraki Go app, and what steps to take to resolve them.

Bad Internet Connection

This alert indicates the connection to the internet is not working as expected. The most common causes of this alert are:

  • The gateway is dropping packets upstream of the device.
  • A recent configuration change (for example, changing the IP address on the GX20).

How to troubleshoot:

  • Check the local status page - often times the local status page gives more detailed error output to help resolve problems during troubleshooting.
  • Wait 5 minutes - the Bad Internet Connection error often reflects a lack of data. After a few minutes, a more precise error is likely to be presented to help troubleshoot.
  • Reboot the hardware - sometimes the MAC address for the internet port can get stuck on network hardware and clear out after a set period of time. Rebooting network equipment helps speed up this process.
  • Use a new cable - a bad network cable can cause this error to be presented.

Bad IP Assignment Configuration

This error means a bad static IP or an incorrect VLAN tag with DHCP is being assigned to the Go hardware. Typically, network hardware will simply not work if you assign a bad IP address to it. Meraki Go hardware, however, will automatically switch back to DHCP (automatic IP assignment) so that it can check in to the cloud and alert you about the problem if at all possible.

The most common causes of this error message are:

  • The device has had a working static IP, but network changes have caused the IP address to become invalid.
  • A typo or otherwise incorrect value while assigning a static IP in the app.
  • The wrong VLAN tag is used for DHCP.

How to troubleshoot:

  • Switch to DHCP - The error message can only be displayed if the Meraki Go hardware has found another working IP address. By switching the IP assignment to DHCP instead of static (only specify a VLAN tag if you know what it should be), the device will keep using the current addressing and the error will go away over time.
  • Need a static IP? Check the rest of the network hardware to figure out what can be used:
    • GX: Typically the GX is connected to the internet. If you require a static IP, speak with the upstream provider to identify the correct IP address information. This can be updated in the app or local status page.
    • GS: Check the upstream router gateway IP address to use, and what the subnet mask should be. If you have a GX in your network, this should be one of the created wired networks (a VLAN) GX IP address as the gateway.
    • GR: Treat static IP assignment on the GR similarly to the GS.
    • Try a laptop or phone - A laptop using the static IP should be successful as well. If a laptop cannot use the IP address, or a phone, the Meraki Go hardware likely cannot use it as well.
