5G 5G21-12W-A Gateway "Trashcan" Bridge Mode

Sadly, looks like my experience is similar.  Well, maybe worse.  I received the trashcan yesterday.  Excelente speeds I've seen is about 19/4.5.  More commonly in the range of 10/2 or so.  Always LTE rather than LTEA.  (As a comparison, a Pepwave BR1 Mini with TMO SIM and OEM "rabbit ears" does better in the same location.)

I ran it all night plugged into one of the WAN ports of my Peplink Balance 210 router and had the router set to disconnect the WAN if ping times to reliable hosts (e.g., 8.8.4.4 and 1.1.1.1).   (WAN supervision is highly desirable when using a load-balancing/fail-over router.)  This AM I was greeted with a log showing more than 100 disconnects over night. 

Yesterday I set up WAN smoothing on the Balance 210 for SIP calls to VOIP.MS.   When TMO ISP was introduced into the WAN mix the calls turned to garbage.  In each case I had to return the outbound connection to Spectrum [uuugh] alone -- then all was OK.

Like others, I was unable to set the trashcan in bridge mode or to invoke DMZ.  That's likely part of the problem but that does not explain everything.

So my experience differs from yours in that the trashcan was unable to handle even the most mild of requirements.   I'll call tech support today but I'm spring-loaded to pack up this POS and send it back to TMO.    (5G?  Laughable.  I'd just like a rock solid 4G connection and I'd be happy with, say 50/10.  I'm sure it works fine in urban areas where TMO has coverage.)
