My LB1120 on Verizon has been working fine for the past 3 months. Last week the unit stopped working. Here is what I'm seeing: Solid amber power light The green signal strength bars are lit as follows: on, off, on, off, on When I plug my laptop into the unit directly I'm getting a 192.168.225.* address. I am unable to connect to the 192.168.5.1 management interface. I attempted to factory reset by holding down reset button for 5 seconds and nothing happened. No factory reset seems to have happened. Anyone have any ideas?

I have the same problem. We have four LB1121 lte modems and one stopped working. Power light is amber. Then 1st, 3rd, and 5th bars are lit while 2nd and 4th bars have no lights. We tried switching sim cards and carriers between this modem and working ones and seems like the problem is limited to that specific modem.Like the OP mentioned I have the same problem where I cannot get to 192.168.5.1 and reset button doesn't do anything. I think it's dead.

Hi mondofresh, Is your device up-to-date with the most current firmware? Make sure you are connected to a wifi or in and area that has good connection before checking. Below is the another way to do a factory reset. https://kb.netgear.com/31171/How-to-reset-4G-LTE-Modem-to-factory-settings Please let me know. :] - Jason N

Physical reset: I have tried the "press reset for 5-seconds" and there is no resultant reset or status change. Lights continue to be lit as described in original post. I have tried holding reset button for over 60 seconds. I've tried press/hold during power cycle When cabled directly to ethernet port with laptop, I am unable to get to 192.168.5.1. In fact, I seem to be picking up a 192.168.225.* address. Obviously I'm not able to get to default 192.168.5.1. I am, however, able to ping address 192.168.225.1. This IP doesn't seem to serve up the management UI. So...it seems like this device is bricked. I can find no documentation that describes the solid amber and every other signal light illuminated condition.

Hi mondofresh, I will PM for further assistance. :] - Jason N

This seems to be a common issue for based the this thread. I recently had a modem that I purchased about a year ago exhibit teh same behavior. At first I thought it was other issues but today narrowed down the issue to the modem. I have default configuratin where the modem assigns DHCP ddresses to connected hostsin teh range 192.168.5.2 to 192.168.5.9. Thsi has been working well since the last year when i deployed it. Today when I connected the laptop to the modem, it assigned an IP in the range 192.168.225.x and teh default gateway was 192.168.225.1. I then assgned a static ip to my laptop with address 192.168.5.9 and coudlnot access the configuration page 192.168.5.1.

The PWR LED was solid amber and all teh otehr lEDS were on. I tried to factory reset them modem via teh swicth but it did not work.
I also went ahead and powerd down teh modem, removed teh sim card and powered it without it and still coudl not access and same PWR LED status. I then powerd down and inserted back the sim card one more time and still no lukc. I tried the factory reset by holding down the switch for as long as I could and still no luck.
Does anybody have any luck or resolution on this issue? Can I make a conclusion that its possibly a hardware issue that just fails excatly afetr one year of use within the warranty period?

Thanks,
E

  Hello all,
  
  I know this is an old thread but I am looking for some answers or resolutions from anyone who might have experienced the same issue. After trying all the diagnostics and factory resets as suggested in this forum I still was not able to resolve the problem.
  
  Thanks,
  E

    I have the same problem, it looks as though mine did a firmware update on its own and that's what sent it spiraling. A factory reset worked for a few minutes, then back to the solid amber light. This product let me down in a profound way, and at a remote site that's hard to get to...never again.

Just thought I would mention that as of July 28 2020 Verizon will not recognize the LB1120 as a certified device. At that time service will be terminated.
