@Clive_A thanks, but this doesn't seem like an ISP issue. The ER605 is connected to a Nokia 5G modem mounted in a fixed location. When the WAN connection drops on the ER605, I connect to the 5G modem via Bluetooth using the Nokia diagnostic app and verify the 5G connection is still up. Every time the 5G modem is still maintaining it's connection and it's still connected with the uptime visible as multiple weeks and months. 

 

The ER605 is somehow dropping the connection to the 5G modem and is not able to restart the correction without me manually logging into the omada dashboard and clicking either "Disconnect" then "Connect" or just clicking "Connect" depending on how the ER605 / controller is behaving. 

  @Clive_A Hi. Thanks for the reply.

 

From some further analysis and finding some related postings, it's starting to feel like an issue with the IP being refreshed from the modem. Each time the drop out happens, and I need to go back in and manually press connect the IP changes.  I found these related posts that seem to confirm similar behaviors and resolution. As a test, I placed a basic router between the 5G modem and the ER605 assigning a fixed internal IP to the 605 and the problem is resolved.  I understand this is anecdotal without the wireshark, but at least it's given a temporary workaround.

 

To be crystal clear - the issue specifically seems to be the ER605 losing the connection (for some reason - seems to be related to an IP change) and not being able to restore the connection itself. I need to log into the controller and press 'Connect' at which point WAN is restored, and all is well again.

Next step to confirm is to run the wireshark with a focus on DHCP as you suggest - which I will aim to do over the course of this week.

 

Regarding some other questions you asked:

 

Is this a periodical drop?

Seemingly random with no visible pattern.

 

Wireshark results that show the traffic behind WAN drops. (Key to this issue.)

As above, will provide.

 

Do you have a log from the ER605 at the timestamp of the WAN drops? Same to the 5G modem, is there a log system?

No ability to access logs from the 5G as the webUI cannot be accessed - only using a consumer bluetooth app. In the 605 logs, no visible errors. Log extract below, along with screengrab of WAN drop outs from alerts panel.
 

What are the ping results when the dropout happens? To default gateway, to 8.8.8.8 or any of the websites you frequently visit.

All failures. Ping results are fine within the network but anything outside fails.

 

Modem uptime does not mean anything. It means the uptime of the booting. Or give me the screenshot of your diagnosis about this "uptime".

Noted. My misunderstanding here. However, the signal remains strong and connected with the 5G modem. This is a Nokia modem, you can connect via bluetooth directly to it and see stats. Modem shows as connected with strong connection. Impossible to watch at the same time as a WAN disconnect happens on the 605, as it happens randomly.

 

5G modem, signal strength? How can you be sure that the sim card is receiving the service perfectly fine with zero down or reconnect time?

Based on best guesses. When the WAN drops, the mobile devices fall back to the same 5G network. This is a rurual location, with only one cell tower -  so it's just an assumption that the 5G is still operational.  However, this issue isn't regarding the down time - it's the fact that the 605 cannot automatically re-establish the connection without manually logging into the controller and physically clicking 'Connect'.

 

What's the IP address on your WAN status when it is "drops"?

Still shows the IP information including DNS but with a red 'Offline' status.  After pressing connect, IP is refreshed, and connection is 'Online' once again.
