Repeated 5G Gateway Failures

Update: I decided to stick with my second Arcadyan gateway/modem and see if I could return to where I was happy with the service and get consistently high download speeds. 
 

After a series of power cycling and resetting the gateway to factory defaults, I started getting more consistent service but download speeds never returned to the high 100+mps that I was seeing during the first 6 weeks of my T Mobile 5G Internet service. Looking back at my download speed history, there was a clear change after August 1, 2022. Since that time my highest download speed has been 30mps with the average download speed of 18mps, barely double the speed of my old DSL service but without the consistent reliability of my DSL service. Also, I've seen two or three drop offs each day where ping times suddenly jumped to 100-800ms and download speeds of less than 1mps. About half the time I've rebooted the gateway, and the other half I had not - it's not clear whether that had an impact or not on the connection quality/speed. I have noticed that upload speeds since August 1st have actually doubled to around 12mps - I'd rather have my old 100mps download/6mps upload speeds. Through all this my 5G connection has been steady at 3 bars. 
 

It's clear to me T Mobile instituted a change to their 5G service right around the end of July/first of August. While my speeds do average higher than my DSL service, the quality and consistency of the 5G service falls short. I will try giving T Mobile support another chance and see if I can get back to my high download speeds. Otherwise the gains I have now over DSL may not be worth the frustration over the drop offs. Stay tuned…..
