Home Internet Gateway Needs Reboot Multiple Times Daily, Internet Access Dropping

Mine is at the same version, and my can never drops below 4 bars.  I'm at 5 bars now and had to restart twice in a row to go from no connection.  I have to restart several times a day, and here lately, 2 or 3 times in a row to get a connection.  Always at 4 or 5 bars. 

I have been on the T-Mobile home internet solution since January of 2021 at what appears to have been toward the end of the BETA period. The Nokia router I have is hardware revision 3TG00739AAAA and it is currently on the 1.2103.00.0338 software version. I have seen at least 3-4 software updates; all appear to take place upon a reboot if it is available. I could not get a download image or push it myself so I believe that is just the T-Mobile control factor. 

I have not observed heat issues with mine. I stated the hardware revision as is could be important. I worked in the industry for 22 years and I know manufacturing runs can have issues. A build manufacturer might use components that are not to the original specifications and a whole release of product is compromised. I have suspected the heat issues might be with the improper bonding of the heat sinks on the chips or not present at all. The insides are pretty obscure so you would have to dig in deep to investigate. Nokia would know how/why the hardware revisions are determined but if it is due to cost cutting for manufacturing, well, not likely they will fess up to that.

In the early 2-3 weeks after obtaining the router we did experience some repeated cellular disruptions. Then the router ran pretty great till June when there were repeated disruptions for 7-10 days. After three calls to T-Mobile support they stated there was work on the tower equipment as upgrades were necessary. It would be nice IF T-Mobile would notify customers in advance of doing work in given locations. This would prevent customers from wasting a bunch of time chasing after issues that are not present. Taking a more proactive support mode makes sense to gain customer loyalty. I don't think they quite get that or the powers that control matters don't want to invest in the support initiative.

I believe is could be a very good thing if there is a new improved router to be released. That is if it is truly better for the customer base and not just a tighter control element for T-Mobile visibility to traffic. Nokia has been in the industry a long time now but over time things change so how they may have done things in the early days vs. how they operate now could be very different. 

Even with the current router the web management interface could use some improvements. The features present with the Nokia router are pretty limited. A more robust router with more local controls would be a welcome addition. The current management options are not impressive. The mobile application is a waste of time and i have found it to be so useless that I removed it from my phone as it would usually hang up and I would have to reboot my iPhone 12 Pro just to get the thing shut down. 

The cellular signal bouncing is a very frustrating issue. The inconsistent service delivery for speeds and quality of signal is another. Local WIFI seem to work well enough but lacks controls. I have used wireless scanners and I used cellmapper.net to identify the towers. CellMapper is only 70-80% accurate for data but is one of the best tools for tower location. The 4G LTE is more complete and I have found the 5G NR PCI values not present on some towers. A call to T-Mobile support and asking them for coordinates to the tower is possible and I recommend it. If the tower is too far away and/or the topology of the landscape between the tower and router is suspect this is important to know. In some locations it is just not possible to obtain a strong, clean signal from the tower. With wireless transmissions there can be external factors that are difficult to resolve. In some cases using an external antenna can improve the solution and make it work. Waveform.com is a vendor that has antenna solutions and they have clear documentation on making the antenna setup and placement. They have engineers that will talk to you and answer questions. 

There are multiple ways to resolve some of the issues and understand what is going on. I found it took a bit of research online and testing here and just trying multiple different locations and positions with the router before I found the optimal location. You can't optimize the router location with the LED on the top of the router. Making a wired connection to the router and using the web interface is pretty important. Understanding the various RF connectivity factors is also necessary. There is a great deal of information online and a quick search of something you observe in the web interface that you don't understand can help resolve problems. When posting to the community more information is better than just a one line obscure statement. 

I spent considerable time getting the solution optimized so I do know it can be frustrating. The T-Mobile solution is maybe not the best for every location but for many users, like us, it has been the most economical and works pretty solid now. The community is a good place to start and on Reddit there are some good conversations. Some are bash sessions and others actually have good information and are worth reading. 

Thats an interesting device. If I had the same issue here I would prefer to push for the newer router T-Mobile is pushing out to see if the newer router has better performance. It would be interesting to be able to compare the operation of the two. I have not had heat related issues with the Nokia I have and it runs for an extended period of time without issues. There have been a couple of episodes where TMO was working on the tower equipment and that led to repeated disruptions but for the most part we have a really solid connection here. I would like to add an external 4X4 MIMO antenna so I could improve the local WIFI delivery with a more central location but the cost is a bit hard to justify. 

I'm experiencing the same issue as others here.  Got the service in January.  Worked perfectly for a month or two.  Then the trash can (Nokia 5G Gateway N1) started needing to be reset on a weekly basis.  Then a couple times a week.  Now daily...Recently multiple times a day.  Signal always comes back immediately upon reset (reset takes 2-3 minutes).  If not home, no ability to reset device which makes Nest thermostat/cameras inaccessible.

I keep my device in my 2nd story window facing where I believe cell tower is (info online for 5G towers is sparse).  Also have the window covered to avoid direct sun/overheating.  Have tried with and without secondary routers connected.  Have tried plugging device directly into outlet, connecting to a surge protector, and connecting to an APS Backup-UPS.  Makes no difference, signal still drops.  Time of droppage is sporadic, but I have noticed an increased frequency shortly after 5pm which I find curious.  If I had to guess, the issue is a software glitch when the device switches between primary and secondary towers.

The current frequency of dropping signal will unfortunately force my wife and I to switch back to a more stable internet provider if cannot resolve (both working remotely and attending frequent video calls).

I called T-Mobile today to try to request the new device that others have mentioned, but was instead told that there were cell towers being serviced in the area over the last few days and the issue should be now resolved [eyes rolling].  This of course would not explain why the issue has been occurring for months on end…

They will be following up in a few days so I will report back how that conversation goes.  Seems like they issue new devices only as a last resort so unfortunately the only way to get one is to keep complaining again and again.

I disconnect when my connection is dropping for about an hour to get rid of tower or or device bugs that I believe triggers a net recycle and has worked unfortunately it happens daily but I'm glad to disconnect for an hour play with the dog and get back to a stable connection.

To provide an update, I believe I've resolved the issue and want to share in case it's this simple for others as well.  I moved my trash can to a window in my home that is OPPOSITE the direction the cell tower is at.  Ever since doing that I've not had to reset the device in over a week and the connection quality usually shows "Good".  Speeds are consistently 200-300 Mbps down and 10-20 Mbps up.

I suggest others who are also having this issue don't give up yet and keep trying different locations, even if those locations are not in the direction of the cell tower.  I have the device in a second story window directly up against the glass (window gets no direct sun so overheating not an issue).  Device is also connected to an APC 450VA UPS (no idea if the UPS helps, but it can't hurt).

Just started with T-mobile home internet (have been a cell phone customer w/ them for many years) a week ago and already experiencing the dropping issues. Very annoying. I have the Arcadyan KVD21 router. Firmware is 1.00.16. I haven't complained yet because a power cycle always brings internet back, but might go back to my old ISP if this persists. Hopefully tmobile figures it out. 

Deployed the KVD21 last night.  2-3 bars anywhere I place the thing.  Up to a dozen disconnects so far on day1.  Rebooted 3 times.  This is all within 24 hours. No point calling and complaining.  I see enough right here in the posts.  Before 15 days is up I'm gonna drop this stupidity like a bad habit.  I'm fine with testing for 2 weeks on non critical things like cell phone and tablet but this TMobile internet isn't close to dependable enough to actually have as a primary network.  So 2 weeks of playing then I kick this thing to the curb.  It is junk 

I just cancelled my service today after 9 months. Service is not ready for wider usage yet. There are many factors which effect the final outcome. Weak signal , load on tower, N41 vs N71 tower type. There are few lucky one who gets 400+Mbps but others get 25-10 Mbps. Total $50 for 10 Mbps is not a good deal.

I don’t need much speed but for $50 it should be minimum 100 MBPS or if someone getting lower speed (because t-mobile towers are busy), then it should be lower monthly fee.

A few months ago power cycling the TMHI box would get us back to something reasonably exciting (~200/25), but for the past month that only works about 30% of the time, and even then it doesn’t last very long before I’m seeing speeds down in the 1Mbps range. 

Seriously!  Still connected, but at the speed of a dialup modem.  

What is interesting is that my iPhone 13 hotspot will consistently deliver over 300Mbs with vastly better ping rates.

Poking around on the net suggests that the Arcadyan kvd21 firmware is crap.
