I was stuck at Orange light today for WAN connectivity at a new site. I had the local person login to the Meraki and we vetted the IP address mask and gateway were correct. I used on ISP DNS and one google 8.8.8.8. Although I think that doesn't matter. We rebooted the cable modem and the Meraki several times. No go. We factory reset the Meraki no go.
They said they put a laptop on the wire and were able to get to the Internet.
Are there any other tools for troubleshooting the WAN connection in the Meraki? With a router I would look at the arp cache to see if the arp of the cable modem were visible etc. Thank you.
