LBR20 keeps disconnecting from LTE

I just got one of the new LBR20 Obri routers with LTE connection.  I was looking forward to this product for quite a while as I live in a rural area without high speed access and all I have available to me is cellular internet connections.  It is a unique product in the market that fits my needs perfectly (without breaking the bank).

 

Since I recieved it 3 days ago, I have been having issues with it sporadically loosing the LTE (verizon) connection which prompts me to have to reboot the router to fix it.  Wondering if this is a potential known problem and if so, are there any possible fixes? 

I have solid cellular service and swapped the SIM out of my old Verizon jetpack (which had it own issues - battery overheating).

It auto configured itself to use vzwinternet for the APN.

 

Thanks,

Matt

    One thing that may be causing it is low signal. Can you see what the signal strength is for the LTE connection?

    Second, Verizon may not be fully supported on the LBR20 yet.

      I attached the mobile status info the router provided.  It shows I have pretty decent signal with a RSRP value of -94 dBm.  Im consistently getting 35 meg dl throughput when the router is up.  So based on this I am shying away from low signal being the culprit.

       

      Do you happen to have any additional information about the router not supporting Verizon?  It includes Verizon's Band 13, so it seems to been built to at least accomdate Verizon.

       

      Thanks,

        OK so you are connected to the Verizon network, so it still may be signal.

        A couple of things to check:

        What are your roaming settings, maybe take off roam?

        Try setting the network mode to 4G, instead of auto.

         

        The Verizon Wireless LTE bands are 2, 4, 5, 13, 46, 48, 66 

  • Exact same issue here on Verizon... works great when it works. LTE Band 13 -60db. Typically I see something like below in logs about 5-6 times daily. Then just gives up. Reconnects in about 30 minutes.

     

    Most likely returning to Amazon as this makes it unusable. Maybe Starlink in the not too distant future...

      Yep blitzberlin. Pretty much what I was seeing in the logs as well. The thing I don't understand is how is it getting assigned new DHCP addresses every 15 or so SECONDS during that supposed downtime period? Seems to me that it has to be getting a data call connected each time - at least enough to get assigned a DHCP address. Could Verizon be dropping the call immediately after it connects and then allowing a reconnect - and then repeating that process several times?? Seems unlikely... Something odd about that behavior IMO.

       

      After a bit of research, I found that they're using Quectel's EG18 module (which, BTW, is NOT among the Quectel modules that Verizon lists on its site as supported...). The connection manager (quectel-cm) is capable of providing more detailed logs, but I wasn't able to find a way to start it up that way on boot... If I can find some spare time I may see whether it's possible via the debug interface to kill/restart the CM with additional logging and see if that provides any additional insight into what's happening. Being an OpenWRT-based device does have its advantages. Thanks to NETGEAR for that! It's normally one of the reasons I buy NETGEAR routers.

       

      But unless I can figure out a workaround soon (or NETGEAR speaks up about availability of a fix), the replacement unit may end up going back as well. I predict a bunch of LBR20 refurbs on the market if this isn't addressed soon. Negative feedback at Amazon starting to stack up.

        Surprising for a new product with such great potential that firmware has not been updated since July?

  • Having the same problem of LTE dropping but using AT&T sim. Rebooting brings back temporarily.  Called Netgear support and they had me refresh the firmware V2.5.2.20 manually using file downloaded from Netgear website.  Will see how long it lasts.

      I have the same problem as you do. I'm using AT&T sim, LBR20 keeps losing signal, sometimes it took around 5 minutes then the internet comesback and sometimes it requires rebooting.

        2.5.2.20 is the original firmware. Unless you flashed new, reflashing the original over the original is unlikely to do anything particularly useful. I did a (support-recommended) full factory reset on mine (which also reflashes the firmware) and it did not help.

         

        My guess is either a bug in that original firmware or an incomplete understanding between NETGEAR and carriers on the status of this device's approval for use on said carriers' networks.

  • For me the issue was the Traffic Meter located under Advanced > Advanced Setup > Traffic Meter

     

    If I enable the traffic meter with no limits the router would bounce the connection around every minute. Once disabled the connection was stable again. Hopefully this will help someone experiencing the same issue.

     

    Router Firmware Version
    V2.6.3.50

  • Has anyone found a solution?  Mine has gotten worse, have to reboot 6 plus times a day.  Then the next day 2 or 3 and the next back to 6 plus.

    I have disabled traffic meter.  No help.

  • Just to be clear, I have legit ATT sim from isp.  When it works its great, but I have to reboot the router many times per day with the router saying "detecting".  This seems like something that could easily be figured out.

      I am in the same boat. A fresh AT&T SIM and it locks up under heavy Zoom traffic. Consistently. I called Tech Support. They said I have the latest firmware and it is AT&T's fault. I am past the return window. It works great when it is not needed. But when peak traffic occurs, it crashes, says detecting for the LTE and has to be rebooted. I am soooo disappointed because when it works, it works well. Just not when I need it.

        Hi BobTech

         

        You mentioned that device is on the latest firmware, can you please provide the firmware version? 

        Kindly describe the ring LED status when issue re-occur. 

        Have you tried resetting the device?
