RV-55 - Connection Dropping

1

We have a few hundred RV-55s in the field. Sims in both primary and secondary slots. With one of the two providers we see some locations are consistently losing connection, while other locations are perfect. Most of the modems were upgraded to the 4.17 firmware, but we still have some on 4.16.

The error logs reference that a socket is open but cannot connect to it. Additional sockets are opened but the modem will not connect because there is already one open. This continues until it appears the TCP idle times out. Trying to figure out why socket options cannot be set as that appears to be the catalyst for the string of failed connections.

Hi @mdsaad,

How many RV55 routers are experiencing the issue?
Do the routers facing issues have the same configuration as the RV55 routers that are working well?
Please share the log files and template files from both the RV55 that is working well and the one experiencing issues with me.

Thanks,

Thank you for your timely response. We have about 50 modems with a specific provider that are experiencing the very poor throughput that was described, but we have the same amount that are not having the issue. I tried to attach the error logs I have on hand, but I the site does not permit me to do that, being a new user.

Hi @mdsaad,

You can upload the log files and template files to Google Drive, then share the link with me.

Thanks,
