NETGEAR 4G LTE Broadband Modem (LM1200) – Use LTE as a Primary Internet Connection or Failover Solution for Always-On WiFi | Certified with AT&T, T-Mobile & Verizon

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 and each port can output >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.

Works great if you just need a very basic failover solution. Speeds are perfectly sufficient for streaming, though you might struggle with 4K. Bridge mode is appreciated. Easy setup if you have some networking experience. Those who don't will probably need to do some googling. Attaching antennas did nothing. It might be CPU limited, but I can't complain for the price.

One star off for the tricky setup. -The device did not automatically find it's download to enable the fail-over mode. You have to search for the firmware for the model number on the bottom, "LM1200-111NAS", not LM1200. -The fail-over mode works but your home router may not support it, so you may have to configure the LM1200 to work in router mode, assigning a static I.P. address to your home router, and configure your home router with that static I.P. address, and if your home router works as a DHCP server you should turn off DHCP in the LM1200. -For all of this you need to understand how I.P. addresses should be setup and I think this is not in scope for most people though it's actually pretty straightforward. Once configured the unit delivered speeds on par with my WiFi hotspot. It's signal strength is very dependent on placement but it has a page that shows you so you can experiment with placement. Overall a good value considering there are not many devices like this on the market.

Great price for a portable 4G router. Can be used in bridge mode or router mode. I have it in bridge mode connected to my Ubiquiti DR7. Not sure what other people are complaining about the firmware not updating. I downloaded the correct firmware for it, make sure you pay attention to the model number, and it added the fail over feature. I didn't activate it because my DR7 can handle that. I was also able to run it from a battery bank without issues. The only negative I can think of is that I wish it could clone IMEI numbers so that it looks like I'm using the ISP provided hot spot. For the price though it's an excellent value, though I wish the external Netgear antenna were cheaper (it cost more than the router!!).

If your looking to purchase this device for the major feature of failover look elsewhere. The price is great for the type of device. But everything comes at a price and the price is the failover does not work out of the box. On the box it states the feature will be available as an update. Great news the update has came out and the feature is available. Bad news you can't update and use said feature. Tried using the online automatic update give me an error. When to the website and manually downloaded the update states the update is not compatible. Called Netgear and have been with support for weeks to no avail. I've noticed that people have gotten their devices to update but they all seem to have a previous revision of the device that ends in 100NAS and the ones recently shipping out are 111NAS. It's shame had high hopes to have a useful feature when our Internet goes out during power outage and/or during severe weather. Netgear pls fix.

This works with Project Fi data sim. No setup necessary - put the sim in and boot the modem ! Be clear about what the LM1200 is - it is intended for "home" use. It does not have a battery - it needs a live USB C connection all the time. It also does not have built in Wifi - you need to plug in a wireless router or access point to get wifi. If you update the firmware ( download from Netgear site ) it can be configured to do be a failover router - so plug your broadband connection into the WAN port and connect to the LAN port. It will use the WAN port until it goes out and then use LTE.

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.

It would have cost more to use this with a cellular plan than to get fixed cellular internet service, so I returned it. Before you buy, shop around for a cell plan and make sure you can find one that works for an affordable price.

This item does not work with operators out USA

Great idea in principal. Be careful: The one I was sent from Amazon was North American specification and will not work in UK. Ensure you purchase LM1200-100EUS if you want to use it in UK.
