NETGEAR4G LTE Broadband Modem - Use LTE as Backup Internet Connection, Unlocked, Works with any Mobile Network Provider (LB2120)

This product does exactly what it says in the box, reliably and without fuss or fiddle.We live in a rural area with low speed (not fibre to the premises) 8Mbps broadband which is insufficient to manage much more than one HD stream reliably.With this Netgear modem, using a 4G SIM, we have a minimum 35Mbps down / 25Mbps up speed which is capable of handling everything we need and so our internet connection is now no longer an issue.I’m using an ASUS AC68U router and simply plugged the Netgear modem into this using a network cable, no fiddling, configuration or messing about required. Job done. Happy everyone.PS I had tried using a HUAWEI MiFi USB dongle to achieve the same thing with my ASUS router and it was unusably unreliable. Don’t know whether the issue was with the dongle itself or with the ASUS management of it.

I work from home so reliable WiFi is essential. After a series of Virmin outages I bought this little gadget and a tenner a month 10Gb SIM-only plan from Three, I connected it to my UniFi Security Gateway and it works perfectly.You can have it send texts when it switches to 4G and back to wireline, and when the data usage gets up to a set percentage of your limit. The only downside is there doesn't seem to eb any web service or SNMP interface to reflect status, so you're left running a script to parse the HTML if you want to show status in your network management tooling.

technically minded and still found it tough to get running. but.. otherwise great and worth persevering.so, out of the box i put a giff gaff sim in and selected the giffgaff apn. didn't work. created a new apn with giffgaffs settings from google, still wouldn't connect. connected it to my existing network and this allowed me to update the firmware. then it connected fine. (tried my vodafone sim before the firmware update & that worked). so obviously an issue with older firmware. good signal strength indoors and lots of useful features like alerts when certain things happen (internet failover, etc.)No 5G support but knew that before buying. No 5G in my area so doesn't matter. is connected not only at 4G but 4G LTE indoors!cheaper than others but performance is fine once setup.

Doesn't stay connected to LTE and doesn't reconnect automaticallyI've bought the LB2120 as a backup to my wired internet connection - when it drops, the network will failover to using an LTE connection. My home is a "Smart Home" so having a fail over for this is important for it to stay "smart".The setup of the router was pretty simple - bridge mode sitting between my ISP supplied router and Google Wifi. Initially the bridge seemed fine and no problems with the cable connections, on an O2 PAYG sim 4 bars, happy days. Unplug the cable and we switch to LTE, back in and we're in business again. Happy days, leave it running in a dark corner doing its thing. A happy camper so far.Checking back in later I see that the LTE connection indicator is red\amber - a quick google and this means LTE is disconnected. OK a quick power cycle and we're back in business, however I'm paranoid now and checking more regularly (there's no alerting or logs to help here!). Lo and behold each time I check we're disconnected from LTE, checked settings, APN, factory resets, restarts and on O2 PAYG (plenty of credit!) it barely stays connected for 2h with a 4 bar signal.OK - so I have a monthly EE sim, try that - the connection seems a little more stable (at two bars) however inevitably I see the box disconnected and have to manually connect it again. Same with a 3 PAYG sim. Added a 4g external aerial slightly better signal - still disconnecting and not reconnecting.Having trawled the Netgear boards for details it's a common problem, no firmware updates available and no obvious answer. This modem simply does not reconnect to LTE automatically (yes I've configured auto connect) when it drops. From the management page, if I click connect it does so first time, having to manually reconnect renders this device useless as a fail over. The inability to automatically respond to a failure (e.g. using a syslog server) just compounds my view that this box isn't fit for purpose.I have until the end of Jan, if no resolution by then this box will be heading back to Amazon. If you do take a chance on this box, don't throw away those boxes too soon!

I felt like I had to write this review based on the amount of negative review there are for this product. For the everyday user who want to use this product to replace wired broadband at home with a 4/3G connection, this modem works perfectly.I have it connected in bridge mode to a Google WiFi and it works flawlessly - I haven't needed to restart it or change any settings from the initial setup. Setting up was really simple, plug into a wall and insert your SIM (micro) within a couple of minutes the modem had auto-detected my mobile network settings and everything was ready to go.From this point you can either use the modem with 1 computer connected via ethernet, or connect it to a router in bridge mode to provide an internet connection to your WiFi network.I spent so long hesitating to purchase this because of all of the negative reviews, but I think the majority of these are in reference to the failsafe mode where it works alongside a broadband connection - this isn't the scenario I'm using it in.
