How does the battery backup option work on the High Speed Home Internet NOK 5G21 Gateway device.  When the device gets unplugged or losses power, the device configures to battery operation, then the WiFi is disabled.  I also tried using Ethernet.  Neither connection method works. 

 

In the manual it says “During battery operation, neither Wi-Fi nor Ethernet connections are supported.” 

 

What is the use to have battery backup if WiFi nor Ethernet connections are supported?  How can I use the device during battery operation?

That is correct. I was sold on the idea that it has a battery backup to operate during a power outage.  While the battery has its use it's pretty useless when you can't monitor the signal from the phone application.

I was wondering the same thing. The battery would be great for moving your device around the house, checking for the best signal. But soon as you unplug it it shuts off and reboots, when it comes back on it has no wifi or internet connection. It does show Bars, but that’s not alot of help, since there are cell 2 connections

Yes, I was trying to move around my house on battery to test 5G signal but then I couldn't log into the thing without wifi! Makes no sense at all. I really thought mine was defective until seeing I'm not alone.

Supports the phone jack that is not enabled or used?  Just a thought.  Many of the cable gateways that subscribers have voice service and use a connected “landline” phone use the built in battery to provide a connection when the power goes out.  This supports lifeline and other services.

I also thought the built-in battery would support the gateway cell connection when the AC power was out but like you have discovered it does not.  Disappointed in this. 

Oh that's a thought. But who has land lines anymore?! Seems more important to support voice over wifi for emergency calls. Plus the thing has a big 5000mah battery which should be enough to keep WiFi going for several hours! 

 

Also, is anyone else losing all wifi settings when unplugging?

Mine does not lose the custom settings I have set when I unplug the wall wart.  I’ve moved it around to different locations and plugged it back in, no lost settings.  It might have done it once when I first got it, but honestly, I was changing settings like crazy and re-booting so I’m not sure if it did it or I did it.

I was excited to see the back up battery, but it doesn’t allow the unit operting when power is unplugged. What’s the purpose of the back up battery???

The battery inside the router is so you can move the unit around to find the best cell signal for the router and to remember settings. If you want bttery back up to use if the powder goes out then you can call T-Mobile, they will send you out a UPS battery back up for your router free of charge. The battery back up they send you will run the router for 12 hours.

No UPS or battery back up to the battery from T-Mobile. Battery is to see if the signal is ok, that is it. Why have a battery in it if it only checks signal, when you unplug it, it tells you nothing, even if power outage. It is very confusing. A battery to charge the battery, but that is not included. NO UPS (Uninterruptible Power Supply) from T-Mobile. There, said it twice.

It is apparent that there is a UPS connector on the back of the NOK 5g21 gateway that allows for true battery backup. The question now is . . . where can we get or buy this Nokia part?

Was unsuccessful in finding the price and availability of a Nokia UPS device for this gateway. Therefore, I just bought a generic battery backup on Amazon.

Update on APC UPS Back-UPS Connect:

After charging for about 10 hours, I was able to stream Netflix movies for over 10 hours. I was hoping for at least 2 hours because that is the longest Zoom meetings that I need to attend from home.
