Home Internet Goes Out Every Couple of Hours

Jumping on this bandwagon.  Couple of points:  iPhone7 disconnected from WiFi SpeedTest gets 150+Mbps when on gateway only gets <2Mbps.  Rebooting 5G gateway restores bandwidth to 200Mbps but only temporarily (2 hours best).  Awaiting delivery of my third gateway.  Dismal tech support:  611 IVR doesn't grok "Home Internet Support".  Must use different phone number for home internet.  Clearly offshore staff that is trying to be helpful, but is hobbled by policy and technology.  Most tech support calls are unintelligible due not to language barrier, but woefully inadequate technology… sounds like they are using a wired phone plugged into similar T-Mobile gateway in need of rebooting ;-)
