So I recently switched to T-Mobile Home internet since it advertises good speeds and no data caps. When I first set up the gateway, I was shocked. Speeds were blazing fast. I was consistently getting speeds between 70mbps and 170mbps. This went on for roughly 6 weeks, and then the service became completely unusable. Speeds were consistently below 1mbps and on a good day I could make it into the teens. I called customer support just about every day trying to sort things out, but got nowhere. I finally got a call from an engineer who said, "I should expect varying speeds based on my location" and closed out my case. Not a single person can tell me why everything worked so well but then tanked. I then called and had them send me a new gateway device. I set it up and speeds were again in the 60-100 range for about 2 days, and then went back to being unusable. I then started to notice that most tests showed my upload speeds to be significantly higher than my download. I also set up a fan to rule out overheating which has made little to no difference. Today, I decided to see if my signal could be the issue, so I drove to the base of the 5g tower in my city plugged in my gateway with full bars of connectivity and ran a speed test. My results showed my download speed at 2.62mbps and my upload at 59.3 mbps. I ran the test several times over about a 30 minute period on both mine and my wife's phone and got very similar results on every single test. I'm holding out for Starlink and will be abandoning TMobile as soon as possible if they can't resolve this issue, but in the mean time, I would like to know if anyone has any ideas as to why these speeds are so backwards or possibly have suggestions for things I can do to try to fix the issue myself.
