5G Home Internet nightly slow down

Thanks so much for the reply.  There is no freeway nearby and the city has maybe 16,000 people in it.  Download speeds range from 300 to under 5 and upload from about 20 to 4.  The patterns of slowdown don't correspond to rush hour but instead seem to relate to peak TV times.  They were especially bad during the evening when the Olympics were on and caused the TV stream to buffer and sputter repeatedly.  I have used the location functoin in the app to find a better spot, although there is no ideal place on the 3rd floor of this townhouse because the only windows are on the opposite side of the nearest tower.  All that said, this has worked exceptionally for 10 of the 11 months I have used it, rarely going below 100 mbps which is adequate for us.  Then the bottom started dropping out at night.  As for the metrics, they are as follows:  Received signal strngth indicator, LTE: Good, Reference signal received quality: 5G and LTE, good.  Reference signal received power:  5G and LTE both poor.  Signal interference to noise ratio: 5G: Excellent, LTE: Poor.  Band:  5G: n41, LTE: b66, Cell Global Identity:  LTE:  31026068876035.   Channel Quality Indication:  LTE:  4

None of this makes any sense to me.  Hope it does to you.  Thanks again.

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.

Et al, Agree with Schwibs I CANNOT recommend this service any longer. I have been a Tmobile HI customer for 3 years. I would preach TMobile HI is the best no need for Spectrum, etc. Fast forward, Tmobile service has degraded to the point that their price lock pricing is not worth it. IF I have to work nights on the internet I will not keep their service due to speed drastically dropping, increased latency and the uplink being no good at 3-5MBs (will not support video teleconferencing). I will give this 4th gateway (within 1.5 years) sent from Tmobile a try, IF no luck will go back to Spectrum/Brightspeed. It was good while it lasted-NEED the US Govt to step in and resolve these large telecommunications companies from robbing us blind.

TLDR—but a good read.

FYSA up front, my background IT professional 20+yrs, newbie to these forums. Take no offense-do not ask me basic 101 questions. I do this for living here and in austere locations.

Seems like after COVID customer service across the board has gone down hill in the USA. Pre COVID laws protected the customer, post COVID the laws protect the companies and not the customer. You see arbitration clause as the norm if we use any service and as companies continue to sub contract, creating roadblocks for us to resolve anything but taking our money. They do not offer money back for the down times/days we have no service (i recall getting prorated credits for days without internet from TWC-I cannot even get that from Tmobile for the nightly decreased speeds/latency that do not support my networks. So hmm I know Im not the only one experiencing this. Tmobile gets 100% of their monthly payment for degrade service-nightly. How is this America? Crazy 180 turn around on services in our country. I have friends stationed overseas paying way less for guaranteed internet speeds, no issues.

I have home internet at two different locations in USA. Never had issues when they rolled out 5GHI in NYC (2022), speeds on Arcadyan KVD21 5bars Excellent-downlink 700+ Mbs/30+Mbs consistently. Second location North Carolina (2022) Sagemcom FAST5688W intermittent between 4bars Very good/3bars Good (Good is majority of the time) 400Mbs/30Mbs. In NC after couple months the gateway started to toggle between N41 (faster) and N71(slower) bands. Troubleshot with TMobile tech dept.-no fix action/no resolution. They sent me a replacement GW (gateway) Arcadyan KVD21 sig strength 3bars Good, speed 325Mbs/30Mbs. Worked great for couple months then same story speed decreased, latency went up. Canceled TMobile, went back to Spectrum for couple months. 

Came back to Tmobile during a promo and cell towers being moded by me. Again Fall 2023 sign up with TMobile HI receive a Arcadyan KVD21, sig 3bars Good, speed 300Mbs/15Mbs drop from last year. Worked great, preached the TMobile script again. This year had more latency issues ping 400-500ms-YES troubleshot with TMobile, yes have the optimum location in house for cell tower reception. GW is 10ft high and LOS (line of sight) nothing but empty fields and then tower. TMobile sends another Arcadyan KVD21. No issues for motnhs speeds good latency good. Now in 2024 i notice in my area when spectrum changes prices and speed availability drops TMobile speed drops as well. Also June 2024 Federal money ran out for the American Connectivity Program ACP ran out, which also means the Federal supplement money the Government gave to these mega telecommunications companies also dried up (did you know that?) Then internet prices go up/speeds go down and the telecommunications company make it seem like nothings changed. For SA the speeds under the ACP program was 30Mbs-100MBs for free to those that qualified, is now a paid plan. During this time is when I noticed my service degrade latency up speeds down, nightly (Yes I have read the TMobile prioritization policy. But where I am at there is no cell traffic at night because the Interstate is closed M-F for construction for months now. Called TMobile to cancel they said we will send you another GW, received today lets see how long this one works.

IF this craps out I'll have to go back to Spectrum hardwire/fiber. Till Metronet starts laying down their fiber backbone.
