    Customers are dissatisfied with the connectivity of the router. They mention that the wifi connection is unreliable and will drop connections. This causes complete loss of connectivity until the LM1200 makes another cellular connection. The device has a 3G failsafe connection, but it's incompatible with other devices. The modem still refused to connect and the device would never connect to LTE. The signal is terrible and the cellular backup connection ceased to work after upgrades on the MX64. Connecting is not possible.

    "...So my first impression is that the internal antenna of the LM 1200 is fairly terrible because I can only get up to around 10 megabytes per second..." Read more

    Web user interface is in HTTP and available from public IP address, a serious security concern!

    Web user interface is in HTTP and available from public IP address, a serious security concern!
    Infrastructure engineer here (I work with large-scale computer networks and servers) so I apologize in advance that some of the terminology used may be beyond layman's terms. Firstly, I should state that my "Wifi signal" rating in this review was reflective of the LTE wireless connectivity for this device. It has no other wireless connectivity. I am using the LTE modem with an external dual-interface antenna, and the signal is still terrible when compared to the USB LTE modem this replaced, from the same location, using the same antenna. Secondly, I will state that I am not utilizing or depending on the "LTE fail-over" functionality of this device at all, it is only being used to supply a second internet connection to a second WAN on my firewall which is handling the fail-over itself.I am writing this review after having spoken with Netgear support at length regarding the concerns I will describe below. Needless to say, their first "answer" for my concerns was that "this is a home product, not a business product." To explain why I purchased this product, it was meant to replace my existing, soon to be retired Sprint EVDO Netgear LTE modem that was already connected through USB to my firewall to provide LTE fail-over in case of loss of connection through my primary internet. Yes, with Sprint having been purchased by T-Mobile, it was decided they would retire the Sprint EVDO network in favor of the GSM network. As such, my novel solution (since there appear to be no LTE USB modems for my current carrier) was to purchase the LM1200 and attach it to a data-only SIM on my wireless account.A simple enough solution in theory, or so I thought. But that was before I received, updated, and configured my LM1200. Given that the LM1200 is designed to be placed in front of your router/firewall, I would have expected the LM1200 to have the ability to configure the web GUI to use HTTPS rather than the HTTP that it operates in (you cannot). I also would have expected the ability to disable web GUI access from the LTE and WAN interfaces, you know, to prevent people from logging into the LTE modem management interface from the public internet. I think the chat transcript from my Netgear support sums this up the best:Bradley F: May I ask what is the purpose of enabling https only?Me: To prevent my configurations and credentials from being passed to or from the device in clear/plain text?Bradley F: I see, for home modem they are only with Http and for prevention, you must keep your credentials as secret as possibleBradley F: We do not have business equivalent for a LTE modemMe: Really. What is the solution then for a business who needs an LTE modem to place on a secondary WAN interface of a firewall for fail-over?Bradley F: We only have BR200/BR500 and Orbi Pro NOTE: These are firewalls, and do not list LTE connectivity as options.Me: If I tried to install this product in that way for a business, I would get fired if they understood how insecure it is!Bradley F: but those are already routersMe: Yes, and I need specifically an LTE modem to augment the business-class firewall I already have.Bradley F: Unfortunately we don't have business LTE modemsMe: Wow...Bradley F: Sorry about thatLet me explain it to you another way. You can login to the LM1200 device using its public IP address assigned to the WAN or LTE interfaces. Because the LM1200 uses HTTP instead of HTTPS, data sent to or from the LM1200 is not encrypted. When you login to the LM1200 from anywhere, the interface is presented entirely in HTTP, meaning your config and password are sent in plain text (clear text), and could potentially be "sniffed" by anyone who is also on the same . I don't think you will be able to see my image names when this review is posted, but there will be only a few. Look for the one that is a list of public IP addresses. That image shows a network scan of the /24 subnet to which my public IP address belonged. Ideally, you should not be able to scan for and find the addresses of other devices on your ISP's network, but in my case, you could. This also means others on the same network can scan/monitor you and possibly capture your credentials when you enter them. "Screen Shot 11-03-21 at 04.47 PM.PNG"I feel, given their choice to make the user interface HTTP, that users should be able to disable or enable the ability to login from any interfaces to prevent such snooping. It is bad enough that Netgear has already saved invaders the trouble of guessing a username (there is none, only a password). As an edge device, the LM1200 should have been released with security in mind, regardless of being a "home" product. I myself have not encountered a network device that offered only HTTP for its configuration interface since the early 2000s. Here we are in 2021 with Netgear's latest offering for an LTE modem, and it appears to have been designed with less security in mind than a Chinese government-issued web chat client. Is it that Netgear doesn't think home users are subject to hackers, script kiddies, and identitiy theft? I assure you, they are, and Netgear should have better security on this from the start.I would also point out that there are some concerning entries in the config file if saved from the LM1200. There is only one account on the device so far as I was able to discern from the web interface. However, even though I changed that one password on my device, there existed still the following line stored in the unencrypted config. Take that as you will:"webd.ownerPassword=1234"As such, until Netgear adds the ability to enable an HTTPS user interface (as they have on mose of their other home/business firewalls and routers) and the ability to limit or disable login access to the LM1200, I cannot in good conscience advise any home or business user to purchase or use this LTE modem as it now exists. Even if a user also intend to place the modem behind another firewall, it would only protect you from would-be hackers for your Ethernet WAN interface (and only while that WAN interface is active). There is no way to protect yourself on the LTE modem public interface!.My device details are listed below, and I will revise this review should Netgear correct these security concerns.Firmware Version: EC25AFFDR07A09M4GApp Version: NTG9X07C_20.06.09.00Web App Version: LM1200-HDATA_03.03.103.201Hardware Version: 1.02021-11-15 Addendum, I had asked the question of the manufacturer, "Will Netgear allow users to prevent login from public ip interface? since the gui is only http, this is a security concern. looking for mfg answer." and received the reply back same day, "Remote access to the modem is off by default, so the admin Gui would not be accessible from the public IP address."I am not entirely sure how to respond to the manufacturer's reply, but I have some screenshots (see attached) from my own modem that would indicate remote management IS possible from the public IP on the LTE interface. I did nothing that I know of to enable this, and if there is an undocumented way to disable it, I would really like to know how.
