Issues using with at&t cellular modem

I’ve mentioned this before but wanted to add some information. My wyze cameras would connect and send video at first using my at&t wireless home cell router, but then would stop both panning and sending video.

A few weeks ago I tried another type of camera, a MIPC panning webcam and it worked right off. So I bought another and both have worked well since. I now believe there must be a problem with a protocol used by wyze that’s not used by MIPC that is not being handled by the at&t cell modem. I did not set up a protocol analyzer so couldn’t debug what was mishandled, but was disappointed not to be able to use wyze at the location with that unit. I have four wyze cameras working well in my other house where I have cable internet.
