Will Latency Improve as the Service Matures?

Hello I just signed up for T-mobile home internet and got my silver 5g router a few days ago

honestly you guys are very lucky if your getting service at all during the day lol i cant even get a web page to load or a speed test from 8am-10pm then at night somehow it works ok but the ping is still very bad speeds are about 40mbps down and .5 mbps upload yea 50kbps upload...with 800 ping on fast the loaded ping is 3 seconds not even measured in ms straight up seconds lol

it seems like they are blocking any data from going through for 12-16 hours a day this is very consistent so far 

its also really hard to troubleshoot when you think your router is broken but its really the service blocking you i spent 20-30 hours moving this thing around reading everything resetting over and over just to realize t-mobile is stoping my data from going through

yesterday i bought a external router so i could shut off all the wifi connections on the grey t mobile router and just use the ethernet to a router with its own wifi and im not getting anymore sent errors so the wifi does seem to cause alot of issues on the t-mobile grey router-it still doesnt work during the day at all but does work better than using the wifi on the grey router-the t-mobile router constantly has sent errors not sure what this means but it seems to really effect web browsing  

sorry for the long reply lol just sharing what ive tried so far i also put a fan on the bottom...lol its cool to the touch now and does seem to hold a stronger connection-still no internet connection during the daytime thought
