5G home internet keeps dropping

Yeah, I still suspect it's possible the issue was heat related.  The one person I talked to at Tmobile that was most helpful ("Haley") suggested that putting a fan on it is her #1 suggestion, and was surprised when my setup w/ fan didn't resolve the issue.  My gateway (well, both as I was sent a replacement within the first couple of weeks) was out of direct sunlight, sitting in a 3d printed stand which really forced air through it w/ an attached PC case fan constantly on high, and the issue still persisted with complete loss of function multiple times a day.  Despite the fan, I could still feel a small amount of constant heat coming off of the top of the unit, so I question what kind of poor design is happening as no modem/router/cell phone I've ever had has shut down due to heat quite like that… I really question if actually COOLING the unit (ie, colder than ambient air) is the only way to make it viable due to the design, or putting it in a basement where air is naturally cooler (but signal would be poorer).   For me however, I ended up sending it back and signing up with a competing ISP.  I hope Tmobile gets their stuff together, as I'd love for some healthy competition to show up in neighborhoods without any other options!
