Home internet modem keeps powering down and restarting
So, we had the Tmobile modem(the 5g tower... black box) for a few weeks now... worked great at first but now it continues to shut down every few minutes and restart. If it does it long enough I have to completely redo the setup on the app. Has anyone ever had this happen?
If it is rebooting like that it might be the power adapter or the gateway has a problem. Contact support or touch base with a local T-Mobile store to see if you can get a replacement. I would see if they will provide both but try the power adapter on the original gateway before you swap the SIM card out etc… Reduce variables to know if it is only the power adapter. That is if you really want to know.
Yes when they work they are great, just received my 3rd one today. Wondering how long before the power cycle starts again
ok the third one didn't work out of the box. After a sim card switch it worked 3 hours before powering off recycle started again.
Im thinking it is a manufacturing issue. U have the 3rd unit coming. First didnt work after a day, exchanged at the local Tmobile store and it worked for 7-10 days. China is known to use not spec'ed parts when they run out of the real parts.. Powering Up.
im also on the same boat. its keep getting rebooted every 30 mins

Thanks for this thread, I have only had the Sagemcom for less than a week and it suddenly started rebooting itself every 15-30 minutes based on the alerts I was getting off the firewall. (Just note, I am still running dual WAN between Cable and T-Mobile Home Internet. So that's why I can still email myself alerts off the firewall.)
I decided to give it a whirl and switch out the stock power adapter to my Anker USB-C (up to 100 watts) adapter I use with my laptops. The stock one says it is 15 watts. The cycle of rebooting for me stopped. After a few hours, I switched it over to a leftover Chromebook USB-C wall adapter that is good for 45 watts. No hiccups or issues after a few more hours that I've seen thus far.
I’ll edit / post an update if anything else comes up, but the recommended solution definitely was worth a try for me.
How has it gone since then?

Having the same issue here… just started service a little over a week ago and our tower has power cycled numerous times. At first I thought maybe it was doing updates ( odd to do that without any warning or in the middle of the day/evening, but….. ) Anyway…. I'm glad to see that it isn't just me. I will be calling or stopping by a store.
I have had a Sagemcom 5G Home Modem for just over a week. For the first week it worked fine. I had it across the room on top of a cabinet with no other electronics in the area. I moved it to other side of the room in the corner with all my A/V equipment and next to my wifi router I am going to use instead of built in router where I cannot change or even see most of the settings. As soon as I did that the Sagemcom 5G Home Modem started randomly restarting and even reset once. Last night I moved Sagemcom 5G Home Modem back across the room and it was fine again. This am I placed Sagemcom 5G Home Modem lower in the same side of room in front of a window and moved my modem over to that side of room but up high on top of a cabinet. Ran an ethernet cable between the Sagemcom 5G Home Modem and my modem. So far so good. Through all of this the indicated signal on the Sagemcom 5G Home Modem has been Very Good.
Could this issue be RF interference?rbunce wrote:

Could this issue be RF interference?Could be a recent firmware update.
Bad Firmware Update Bricks Over 30k T-Mobile Home Internet Modems
Mine connects and works fine… for awhile… then reboots… not as bad as that update… but reading these comments it looks less like s/w and more like hardware issue of some sort…
