5G Home Internet nightly slow down

Been having the same exact issue. Every night it slows down significantly. There is no change in placement that improves the situation. Any desire to solve this problem TMobile? 

I am new to t mobile as well and experiencing the same issue. Slow down isn't even the correct term for it. Took 4 hours not not even see a half hour episode! Reset the device so mant times my head hurts and I live within sight distance of a tower. I left a service that wasn't fantastic but so much better than this and not able to get that plan back as it is no longer available. T mobile needs to step it up quickly or ditch the false advertising thst is currently being used! So frustrating and disappointing!!! 

I am having the same issues.  Service was great for about 8 months and now is terribly slow and almost unusable in the evening.  My guess is that the network is congested and needs to be upgraded.  I’ve done a ton of repositioning and closely watching the metrics to get the best signal possible.  
 

I not only have slow speeds, but extremely high latency which is terrible for trying to play games online.  I can’t recommend the service any longer.

The CEOs policy is to oversell the network and degrade the quality for all to boost subscriber counts. I hope his shareholders start to discover that his business strategy is unsustainable and will cause massive turnover to Verizon and AT&T as their more stable networks continue to expand. The gaslighting tech support alone makes me have zero loyalty to T-Mobile. Unfortunately, options are limited where I am at so I have to endure until a proper ISP comes along.

I've read all these stories that share the same issue as I'm having and am wondering if I should even bother contacting support or if I'll just waste my time and they won't do anything to fix it.

Having the same result here, but my upload speeds never change. Daytime is 150/70, evening is 10/70. Seems that only download speeds are affected. I have called support twice. The first tech reset something and fixed immediately until the next day. Called that evening and this tech could not fix anything. I’m currently waiting for an engineer for the elevated ticket. Hopefully someone can fix this issue as it’s obviously not my gateway as they “suspect.”

@ECMP it is helpful to have your gateway metrics and an understanding of your location. Are you located near a freeway? If so, the morning and evening commute traffic will impact your signal (download/upload speeds) as T-mobile prioritizes cellular traffic over home internet traffic. For example, I am near a freeway and my speeds drop to about 90-110 Mbps down during commute hours and rise to 150-250 Mbps at night with less traffic. 

Using your T-Mobile Internet app, tap the “MORE” link at the bottom of the screen, then Advanced cellular metrics, then 5G. What are your RSRP, RSRQ, and SINR metrics? Which band are you connected to (n41 or n71)? 

See the chart below for interpreting the metrics.

So I finally got a tech that knew what they were doing, once she force pushed the firmware update it started working again, haven't had the nightly issue since it got pushed and installed, going on about a week now..

@CookieJ if you have the T-Mobile home internet service, then you must qualify for being in a 5G network area and able to receive a 5G signal from a nearby cell tower. 

That said, let's try to diagnose the cause so that we can resolve your issue. Please answer a few questions that will be helpful in the diagnosing the problem. 

1. Did you use the Placement Assistant in the T-Mobile Internet app? If not, you can access it from the app Home Screen: tap the More about connection quality link on the Home Screen > Launch placement assistant > OK! Let's do this > you can watch the video if it will help, then “skip video” which will launch the placement assistant > enter your address or share location (if you use “share location” and your address shows up then you are assured to be connected to the network). It will take 30-45 seconds to confirm your location.  Use the “Camera” mode for a direct visual of where your cell tower is located to where your gateway is located in your home. Try to make sure your gateway is located in a high point of your home and clear of any obstructions. Here is a helpful video: 

    

2. What are your metrics - now that you are confident your gateway is located in the best possible location, your metrics will show the quality of your connection. In your T-Mobile Internet app > tap “MORE” at the bottom of the Home Screen > tap “Advanced cellular metrics” > tap “5G” > and let us know your RSRQ, RSRP, SINR and which band you are connected to. You should be on band n41 or n71. Look at the chart posted above in this thread for. the ideal readings. to get the best readings, slightly rotate your gateway about 1/8th of a turn and then check the metrics to see if they change for the better. Repeat until you get the best metrics.  

Let us know the results. I hope this helps. 

Just sad and false advertising. It's not unlimited data, in any way. I've unfortunately have had their home internet service since it was originally introduced and have suffered from these random speed changes the whole time. At first, I would have to reset the gateway every few days, now it's daily. My download speeds are as low as 1.0 mbps, that's ridiculous. It tests in the 100's of mbps during the day but as soon as 7 o'clock arrives the speed disappears. Numerous changes of placement, countless of calls and yet no changes whatsoever. Support's response? There's always maintenance being done on the tower. Always. Just as there's always a ticket that's been placed prior to my call. And yet, after all of this, not a single change. Which is exactly why I'm switching to Verizon. I highly recommend it to everyone else, they're rated higher/better than T-mobile for home internet providers for both speeds and service. I'm just tired of the same scenario, with the same useless response/solutions. Anyone remember the definition of insanity? 

For my 1st 8 months or so I was bragging about Tmobile coverage and Higher speeds (over 75mps) than my Xfinity “high speed”. Since then my highest daily speed has dropped to around 30mps (off peak hours) and my average download all day is 10-20. In a multiple TV house we hit the max gig throttle in the first couple of days in the new billing period. Terribly disappointed with them and I am now in search of alternatives.

Boo, tsk tsk to T-mobile, false advertising, rehearsed support scripts, non High Speed, non-unlimited.

Truly limited and not very pleased. (forget trying to do any gaming anymore)

Clearly, I’m not alone.  I’ve observed internet speed slowdowns at night this past month.  Prior to that period the internet service was rock solid.  I’ve rebooted the gateway, checked the metrics which show excellent, and still during the night streaming tv becomes an issue.  This is unacceptable.  This is not a gateway issue but a network management issue.  I use speedtest and other speed test tools and my speeds have dropped below 1 Mbs and of course, my tv stops streaming. During the day, speed tests reflect from 150 to 200 Mbs.  Network load balancing and stablily seem to be an issue.  If this is not corrected soon, I’ll have no choice but to seek other services.
