AT&T Netgear 781s reboots continually whenever connected to 4G/LTE network

I've a Netgear 781s hot spot and it'd connect to AT&T 4G/LTE network fine but then would reboot after a few minutes..


If I remove the sim from the hot spot then it does not reboot.. The same sim works fine on another hot spot so it's not the sim..


I've reset to factory settings many times... I also tried to update the firmware to the latest release but it would not download successfully or tells me that my software is up to date (which it's not)...


Please advise.. Thanks.

We'd love to help with with this. In most cases, we would advise you to attempt to update the firmware and reset the device to factory setting. We're glad to hear you've tried that. Are any of your wireless devices having an issue staying connected to the wireless signal? If so, we'll want to check your local network strength to make sure that isn't the concern.


It maybe time to consider replacing the device. Do you have it covered by insurance? If not, we'll want to see if it's covered by warranty with Netgear or covered under warranty with AT&T.


Please let us know if your other wireless devices are receiving a solid signal and if the device itself is either covered by warranty or insurance.


Have a great week!

This was happening to mine as well. Mine was stuck at FW v.57 and would never update to the .75 that it says it should be at. AT&T CSR tried sending a manual update to it, but it would just say "Update error" and never update. It used to work just fine, but noticed in certain areas that it reboots every 10-15 minutes.

Called AT&T again and they are sending me a Nighthawk hotspot as a courtesy since I've been a long-time customer.

My wild-(Edited per community guidelines)-guess is that this unit is older, AT&T have updated their over air systems and something is freaking this unit out now. Maybe it still works in some areas okay, and some not so okay.

Wanted other to know that you weren't the only one, and what their resolution was. I'm curious to know if the .75 FW would have fixed it, but I will never know. Sounds like LANWANONE had the same issue.
