MX100 - Both WAN ports suddenly stopped passing traffic

[Jorge_]

Today, suddenly, our MX100 randomly dropped both WAN connections completely. Shows offline in the Meraki Cloud dashboard.

WAN 1 Internet is not registering any connection or traffic at all, no lights. Upstream device registers link connection.

WAN 2 Internet registers link connection, solid green only but no activity. Upstream device registers link connection. Strangely enough, when I remove the cable, the solid green link light stays on.

Connectivity provider confirms both upstream devices are functioning properly and that neither upstream device was receiving a MAC. I bypassed the MX100 and verified connectivity myself.

The MX was functioning properly this morning and bam, lights out, literally.

On troubleshooting, I tried accessing the MX locally and the default local password wouldn't take at all. Resorted to factory reset and I was able to access the local config (verifies that LAN side is working). Tried to reconfigure the WAN ports again, but the MX was still reporting "The security appliance is trying to join a network or find a working ethernet connection"

FW: MX 18.107.2

Opened up a case, but it seems like an RMA is in order.

Anyone seen this before?

Hi @Jorge_ , sounds like a device failure. Had something similar with an MS switch - lights on but not passing traffic.

how long has the MX been running and when was the firmware upgraded?

The MX has been in service since 2015 (!!) so I guess it's done it's time. Haha.

I contacted support over the phone to follow up on the case and they just RMA'd it with the info provided and not much additional questions.

😁 8 years. Not too bad. Interesting, will they replace with an MX100 or MX105?

Sorry, made the mistake of thinking out loud. The mx100 isn’t EOL till 2027.
