DHCP Option issue

If your gateway APs are reporting the following alerts:

  • Alert: This device is having difficulty contacting the Meraki Cloud
  • This gateway is disabled. Its Domain Name Service (DNS) configuration is not working.

Your DHCP server may be incorrectly configured to use DHCP Option 5 "Name Servers" instead of DHCP option 6 "DNS servers." Meraki access points support DHCP Option 6 Domain Name Servers. DHCP Option 5 is for setting Internet name servers and is not supported. 

Please review your DHCP server setup guide for assistance with configuring DHCP options.
