## Description

Netgear 4G LTE Modem - LM1200-111NAS

Review: Excellent Emergency Internet Backup - Excellent source of emergency internet...with some "Netgear things". My caveats are as follows: 1) I have fiber as my primary internet, this review is NOT for the LM1200 as a "daily driver". 2) I do not YET have an external antenna so this review is NOT to discuss performance. 3) I use GoogleFi, so my experience is limited to Tmobile network via googleFi. The Good: 1) It is small, my 5 port switch, and GoogleWifi route nest nicely on top of this unit. 2) Powered via USBC! and although the manual specifically says to use their adapter...it works fine as long as your power brick outputs enough watts per port for all your connected devices. I have one power brick powering my 5port switch, GoogleWifi router, and the LM1200 - each device draws 20watts continuously. This saves plugs on my battery backup. 3) It supports failover* its just not very graceful in my application (see the bad). 4) you can turn the LEDs off! (a horribly underrated feature and something I wish would catch on). 5) Supports external antenna connections. The bad: 1) My unit did not support failover outright; needed a firmware update. My quick install pamphlet did at least say that failover would be implemented in a software update. 2) In typical Netgear fashion, the auto firmware update failed to find an update and I had to download it onto my PC then upload it to the device. 3) I did my tests with the LM1200 in bridge mode. When failover occurs, the LM1200 reboots when switching to LTE and then reboots again when returning to broadband; so you will have 30-60s disconnects when switching. This may not be an issue when the LM1200 is acting as the router...but GoogleWifi wont work at all if it is double-nat'ed so I did not attempt to troubleshoot this. The indifferent: 1) No built-in antenna and therefore unassisted speeds are poor. A warning should be more obvious that an antenna is required not optional.
Review: Slooooooooow boot up time, I should not have upgraded - A clear downgrade from the M5 for everything other than the cool mini-screen. - Sometimes takes *minutes* to boot up and connect. All previous versions booted up and were connected in 30 seconds max. A family member also purchased an M6 Pro and experiences the same slow boot times. - If you switch from battery to AC or the other way around, at least one bootup is required. There have been times I've had to wait a few minutes to use the device. If you run this on AC and leave it always on, I'm sure it works great. But if you travel with it or switch between battery/AC, or if you are accustomed to the fast (30 seconds or less) boot times of more current consumer electronics devices, this will be a disappointment and I'd stick with the M5 or earlier.

### ⭐⭐⭐⭐⭐ Easy to setup
*by M***8 on December 8, 2025*

Works perfect, inserted sim and powered on, everything auto configured. Please note to buyers, this is a cellular modem only with wired Ethernet connections. There is no wifi whatsoever with this device.
