LB2120 lte modem cannot access menu after software update

I have the same issue sometimes after firmware update I have to turn the nic off then back on remotely and it fixes it, try unplugging and then plugging back in the nic if that doesn't work I would try restarting it.  When you update take your time don't rush it, let it download wait a min or two to make sure it's really finished then click update once and even though their isn't progress just let it sit and wait and it should reboot after time.

I use the LB2120 (connected to my Orbi AC3000 with "bridge" mode) for my home internet, using AT&T LTE service.

After updating the firmware a few days ago, I ran into the same problem. I could no longer log into my LB2120.

Solution: I held down the reset button (small hole in the label on the back of the LB2120) for about 5 seconds to return it to factory settings. Then I was able to log in again on Windows 10.

I've had significantly faster upload and download speeds since the update , but once or twice a day I lose internet and need to reboot the LB2120. Previously I needed to reboot the LB2120 about once every 1-2 weeks.

After reset the LB2120 are responding to 192.168.5.1 but have anyone seen the "whats new" info for the new firmware?

Netgear list this product as "Firmware not available"...
