Connected, No Internet
We've had TMobile Home Internet for several months, and it's been rock solid from day one. Until the last 24 hours. Every 10-30 minutes or so, our devices get 'Connected, No Internet', and th...
I would do a factory reset. Do you know when you device was upgraded to the new version? Was it last 24 hours? This is the new Version:1.2103.00.0338, If its updated something could have caused an error. A total reset is the best way to clear that. If this first doesn't fix the problem, then you need a device replacement. Good luck to you.
K4VW - Which GW do you have? The Nokia or the Arcadyan? If the 4G LTE signal source is changing bands what about the 5G NR signal? Does it also change? I am guessing both change. When you have the internet working with each 4G LTE signal check the PCI values for ambos 4G and 5G. I believe with the Arcadyan seeing the PCI values would be possible with the mobile application. With the Nokia I prefer to use the browser from my MacBook Pro. If you have a client that you can connect to the wired Ethernet vs. the WIFI when the internet is reported down just try to ping 9.9.9.9 or any DNS server on the internet and the gateway IP 192.168.12.1. Do both the wired & wireless fail or not? You need to look at the cellular information & confirm the cellular signals are both down when it reports no internet. I would assume both would be down but when I was seeing disruptions here back in late June 2021 it was a similar issue. I have not seen the download speeds vary as much unless there was a tower issue and the engineers were working on it.
The reason I ask about the PCI values for both 4G & 5G is so you can confirm the GW is making a transition to another tower. With the PCI, physical cell identifiers, you can use those to locate the towers and then use Google Earth to determine the distance to the towers. If you are on the edge of two cells and the signal is making a transition, that is not working well, that might account for the behavior. I say might as work on the towers could well be taking place. The distance to the source of the signals is important. The 4G LTE can travel farther out. The n71 5G will travel and penetrate better than the n41 GHz signal. The n71 can radiate out maybe 10 miles but is really not as functional beyond 5 miles. It all depends upon the terrain and IF true line of sight is present between the source and node receiving the signal. The n41 signal can really only reach out about 3 miles but to get the rocking speeds you need to be closer in. A good clean n41 signal 1.5-2 miles provides great results.
The cellular metrics for RSRP, RSRQ & SINR help to profile how the signal is received. That will change with environmental conditions. If you are between two towers and on the edge of both that could lead to the gateway making a transition from one to the other but that might be impacting the active sessions causing them to hang at times. If you get more data on the operation it is possible to work on improving behavior. Of course if the tower is being worked on then just have to find out from T-Mobile.
