Review: A quality bit of kit and well worth the price. - 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.
Review: What a brilliant bit of kit! - 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.

## Questions & Answers

**Q: Isn't there a cheaper device to just have my SIM card provide a home wifi hotspot without tethering from my phone?**
A: There are possibly quite a few alternatives. This product does what I require and I chose it after trying out some cheaper products which didn’t provide the same results. As John Ruskin said

“It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that's all. When you pay too little, you sometimes lose everything, because the thing you
bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot - it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.”

**Q: Does this provide a static ip address when using a sim card only for connection?**
A: Dear Amazon Customer,Thank you for your interest in the NETGEAR AC785.The IP-Address you receive with the aircard is up to your provider and can be changed after a logout/shutdown.If you have any questions, you can also check out our community at any time https://community.netgear.com/t5/English/ct-p/EnglishBest regards,NETGEAR Amazon UK

**Q: Can you set this to use specific 4G bands only?**
A: Unfortunately this option is not available on the Netgear LTE modem LB2120.

**Q: HeIp, got this a few months ago, recently the device goes unresponsive every 2-3 hours, the signal shows 1 , reboot  only option to get it to work ?**
A: Have you tried inserting another SIM card and check if the problem persists?
If you do not notice any change, a factory reset would be advisable.

### ⭐⭐⭐⭐⭐ What a brilliant bit of kit!

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.

### ⭐⭐⭐⭐ update firmware before use
*by J***E on 20 December 2021*

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.
