AT&T Netgear MR1100 NightHawk LTE Mobile Hotspot WiFi Router Setup

The AT&T Netgear MR1100 NightHawk LTE Mobile Hotspot WiFi Router is one of the few mobile hotspots available that includes an Ethernet jack. This makes it possible to use the hotspot for desktop computers, printers, routers, mesh networks, and other devices with wired Ethernet connections. At an event or remote location, it would be possible to setup a mesh network for a greater WiFi coverage area.

Setup Warning

When powered on, a message on the device will state that you need to visit http://attwifimanager to setup your hotspot. If you try to visit that address from a computer or any device not connected to the mobile hotspot, the address won’t work. You might even end up at a malicious or fake website. You’ll need to connect to the hotspot with an Ethernet cable for setup.

Setup Process

If you purchase the hotspot at an AT&T store, you should be able to get assistance with setup in the store. If you purchase the hotspot from Amazon, Best Buy or other vendor, you’ll need to contact AT&T to have the device activated. You can do this by using the AT&T chat support or by calling AT&T.

Ideally you will need to have a desktop or laptop computer for setup using an Ethernet cable to connect your computer to the hotspot. When you open your browser, the hotspot setup process will begins. First you will be asked to provide a new hotspot admin password, and then asking you to choose a name and password for your new wireless network. Once the setup is complete, you can go to the hotspot control panel dashboard to monitor usage and settings by visiting the http://attwifimanager on a computer connected to the hotspot.

Device Benefits

When powered on, the hotspot will display the data usage percent and total, including the rollover data. For example, if you have a 20GB data plan, and 10GB has rolled over, you’ll see 30GB total capacity available and the percentage of that total that you’ve used for the billing period. The days left will also be displayed. The hotspot will likely have a better signal and improved bandwidth compared to using a smartphone as a hotspot.

  1. Already pay $60.00 up front to roam international last year which it didn’t work ! will I still be charge if I use in again on my Night-Hawk device I will be leaving the country soon?

  2. Thanks for writing. You should contact the cellular company about a refund of the $60 payment since roaming didn’t work. They might be able to answer your other questions also.

  3. Very poor coustomer service I bought the device and was on the phone for two hours and no help I need someone who can help if you don’t want to lose a coustomer call me 6103864905

  4. Thanks for visiting our site and commenting. Your message seems to be written to the tech support people for the device. They probably won’t be reading this page or your comment, so you’ll want to contact them directly through their website. If you get a bad customer service person, you may need to hang up and call again. Or, try using an online support request form. It’s definitely the case that customer service quality seems to be in bad shape for many companies.

  5. I cannot log on to the attwifimanager. I was on the phone with CS and they told me to do a reset, now I have to set it up and no way to do that.

  6. You may need to have an Ethernet cable connected from your computer to the router, and then go to the appropriate IP address such as to access the router login page.

  7. The device says I have 8 messages but I can’t get to the website to get the messages!

  8. Hi Jamie, That’s a good question. I’d need to check the user guide to see what “messages” refers to. Perhaps it refers to text messages or general service announcements. You may want to call your carrier or service provider to find out.

  9. MR1100 states Mobile Broadband Disconnected- Your data connection is disconnected. This unit worked fine yesterday and nothing has changed on our end

  10. Have you checked with your carrier? If the hardware still appears to be functioning then the problem could be with the carrier. I presume you’ve restarted the unit. You could also see if there are any firmware updates available.

  11. AT&T customer service does not seem to know which department can help with the wireless hotspot and needs serious help and housecleaning. How can I connect the hotspot to a computer without an ethernet port? It works if I connect it as wifi but then should/can I connect it to my home network with an ethernet cable?

  12. Hi Mary, Sorry for the delay in replying to your comment. You should be able to use an Ethernet cord or use WiFi to connect to your AT&T hotspot. It can also accommodate a ‘switch’ (which gives you additional Ethernet ports) or a ‘router’ to provide Internet service to an office or home. However, the connection speed and data plan may limit how much you would want to use it that way.

  13. Hi Steve,

    I’ve not researched whether or not a person can login remotely to the AT&T MR1100. I presume you are referring to accessing the device from another location. If it’s not possible, I suppose a person could setup a remote desktop program and a dedicated laptop or something. Then access it remotely by getting to a system on that network.
