NETGEAR Nighthawk M6 Pro Mobile Hotspot 5G mmWave, 8Gbps, Unlocked, AT&T, T-Mobile, Verizon International Roaming 125 Countries, WiFi 6E, Portable Device for Travel, Modem Wireless Router (MR6550)

We tried to switch from Spectrum ($75 a month) to T-Mobile's 5G WiFi a while back to save some money, which was $40 a month. In short, I could never shut down Spectrum because the 5G WiFi is constantly losing contact with the cellular towers, so we'd have to reboot it about once a day. It's on the top floor of the house, so someone had to constantly go up and down the stairs to reset it. Finally gave up. Negotiated a new price of $30 for Spectrum, but we still need a back up because every once in a while Spectrum goes out. We live in a semi-rural area where storms and such can cause problems. So I explored this thing...I bought the LM1200 version about a month ago, and ordered another cellphone "line" from T-Mobile, which costs us $15 a month. They sent me the SIM, which I first plugged into my phone to make sure it was working, then plugged it into this thing and turned it on. Very easy setup. Connected it to a WiFi router I had, and magic! It all works as intended.Of course, it is running at 4G LTE speed, to the device. When I connect various PCs and Phones to it from throughout our house through the WiFi router, I'm seeing speeds of around 18 Gig. That is, until we hit our data limit with T-Mobile. Then T-Mobile does not throttle our data, but they do deprioritize it. So when local cellular traffic is heavy, Our WiFi can slow down to 1 GB or less, which is slow, but better than being disconnected when Spectrum goes off line. All critical things such as our security system, etc. remain on line, and internet access via our PC is still functional but can take few seconds to load.The quality seems good. I did add external antennas that are supposed to help improve the 4G LTE signal, which cost about $10 and needed small adapters, but it was not apparent to me they materially helped with the signal strength, but maybe.Overall, very pleased. Works as expected and as a back up system, after the upfront costs, saves us about $25 a month.Highly recommended.

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.
