NETGEAR Nighthawk M6 5G Mobile Hotspot, Router with Sim Card Slot, Modem, Portable WiFi Device for Travel, Unlocked with Verizon, AT&T, and T-Mobile, WiFi 6, 2.5Gbps (MR6150)

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.

I have a Netgear LB1120 LTE modem as a backup for my home network; I thought this would be a good upgrade to 5G. I was wrong.For a whopping $700, I expected this to function, but it barely does. Half the time it would struggle to actually hand out an IP over the LAN port (inconsistent). If you enable IP Passthrough mode, you can't change the admin IP address -- specifically, you CAN (and you have to also change the DHCP range, even though that's irrelevant), and then it forces you to reboot, and the screen will show the new IP address, but the old one still works and the new one won't, but if you change it BEFORE enabling passthrough (then reboot), and then enable passthrough... it works. It doesn't help that the touchscreen is super laggy and frustrating to interact with.But remember the inconsistent IP assignment when working as a router (passthrough off)? Same issue with Passthrough... it was inconsistent.And the device takes 5 minutes to reboot.... which you have to do any time you change nearly any setting other than turning WiFi on/off. Even installing/removing the battery while plugged into the wall causes an error message on the screen saying it has to reboot to change the "Power Mode" setting... while it's still on and powered, but adding/removing the battery causes it to change some setting... that requires a reboot. If you start it out-of-the-box for the first time before installing the battery, it will also immediately boot to that error/warning... wait 5 minutes to make sure you see it, and THEN reboot.And, in the 3 short hours I was trying to get this to work at all, it somehow decided my APN setting was wrong and stated showing the network as 000-00 and just wouldn't connect. Manually selecting the correct APN for my carrier caused to to complain and throw errors about how this was OBVIOUSLY wrong. Reboot. Again.The real cherry on top here was that when it DID give out an IP address, it caused my router (an Ubiquiti UDM-SE) to lock up for 10-20 seconds every few minutes. I don't understand how or why, and it was the same in NAT/Router mode and in Passthrough/Bridge mode.If this was a $100 device, I'd probably debug it and poke at it with Wireshark and see what packets it is sending out the LAN port, but for $700? I expect some amount of QA and polish... and a functioning device out of the box. As such, I'm just returning it.I'm sure it's probably fine if you're using it as a hotspot, but as-is, this thing doesn't function as a 5G modem for your network and is incredibly frustrating and fiddly to even try.
