MX67C Won't Connect to internet

[Radium]

Meraki MX67C Firmware

Current version: MX 18.107.2

MX will no longer connect to ISP/Internet, using PPOE with Authentication & VLAN tagging, was working before Christmas, customer powered down network equipment including Fibre ONT and now Meraki will not come online.

Steps taken to date:

Rebooted MX, Factory Restore x 2 , also tried using DHCP and LAN2 port configured to WAN, still will not connect, configfured a MX64 as a test device on the same connection and it connects to ISP with internet.

Have created a ticket with Meraki support & waiting for their response. MX67C was purchased Mid 2022.

Any suggestions, welcome.

Have you checked with the ISP if they can see the ONT as being online?

[Radium]

Yes, they can't see it, also tried at workshop, different WAN circuit, same issue, I can get my test unit to connect but not the customers one

[BlakeRichardson]

If the ONT isn't working then you need to deal with the ISP it's not an issue with the MX. 

[Radium]

The ONT is working fine

Is your network adapter updated or working properly?

I have heard of someone else having a very similar issue with the MX67C.

Was there a firmware update (check the Meraki dashboard)?  If so, I would roll back that update.

You can also check the Meraki dashboard change log to see if anyone changed anything after Christmas until the issue was discovered.
