Unreliable home internet

I've been having the exact same experience with mine. I've concluded that "tower maintenance/upgrades" is a b.s. response from tech support when they don't know what to do. Several times I have been told maintenance/upgrades had taken place recently and each analyst said it took place on completely different days when I spoke with them all on the same day. T-Mobile rushed this service into rollout before it was ready and they are making excuses or trying to paint the perception that they are modernizing their equipment all of the time. I'm on my third replacement gateway and ready to drop TMHI.
