If your gateway APs are reporting the following errors:
Your DHCP server may be incorrectly configured to use DHCP Option 5 "Name Servers" instead if DHCP option 6 "DNS servers."
Meraki AP's 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.
