Losing connection to ER605
Hi.
We're having an issue with an ER605 v2 router on a customer site whereby the site keeps losing internet connectivity. The router is an ER605 and is controlled by an OC200 controller. We're in the UK and are using a PPPoE connection. We have a carrier-provided modem/router which has been configured in bridge mode. From the carrier's portal, we can see that the modem is not losing connectivity as the sessions are remaining online. From outside the network, we are unable to maintain a connection to the Omada Controller as that keeps showing as offline or sometimes online but without an IP address. From inside the network if I set a continuous ping running from one of the PCs to the router interface (.254), the controller interface (.103) and Yahoo I will see packets randomly dropped to both Yahoo and the router interface. Then there may be a prolonged outage to both the router and Yahoo of 5 or more minutes. The controller continues to ping but that is connected to the same PoE switch as the EAP245s that I'm connecting through. From our office, our Zabbix server sees the router as being online albeit with varying ping times. The router has a 4G modem attached as well which is configured in fail-over mode via the controller. The 4G service does not look to kick in despite the controller showing that interface on the router as being online.
Does this just sound like a faulty router? It was only installed a couple of months ago and has been solid up until now. Any ideas would be welcomed!
