LB2120 won't auto-connect after an outage

Hello I have a LB2120 providing LTE backup for my primary internet line. It is connected in failover mode to a pfSense firewall as a standby interface. Signal strength shows as 2 or 3 bars, and pfSense fails over correctly to the LB2120 if my main connection goes down. All good so far - but... If the LT2120 drops connection to the cellular network (i.e. looses signal in a weak signal area) you have to log in to the user interface and click 'Connect' - then it connects again instantly. This happens in both Bridge and Router mode. I'm running the latest firmware. My concern is that the device is totally useless as a failover modem if you have to manually click connect if the signal drops!. Is there any way to force the modem to automatically try to re-connect if it looses signal? Any advice appreciated! - Dave

  • I've solved the problem myself - and now have a reliable failover connection.   The steps I took were:

    1) Disconnect Netgear LB2120

    2) Throw in trash can

    3) Replace with Yeacomm 3G 4G LTE Router

    4) problem solved.

     

    I seriously wouldn't recommend the LB2120 - wish I had purchased the Yeacomm in the first place and not bothered with domestic grade products.  Could have saved some money as well.

      What is the specific model?  I found the "Outdoor" model.  The Yifan website also lists an "indoor" model and some other models.

        I now use these - very reliable - you can get them on Amazon:

        Yeacomm Outdoor 4G CPE Router, 3G 4G LTE Router with SIM Card Slot,150Mbps CAT4 Mobile Router, Without Wifi (4G ROUTER)

  • Same experience.
    A scheduled curl script should solve it, sending the reconnect request.
    If you know curl, please try and share :-)

      You shouldn't have to mess around with scripting just to get a product to do what it was designed to do - and clearly doesn't.   I've had the same problem with 2 of these units - and the best solution is to throw them away and buy something which performs as advertised.  Since I've moved to the other vendor's product  I mentioned in my earlier post I haven't had a single issue.   Good luck!
