Sudden loss of signal after 3 years of flawless service.

My T-Mobile home internet worked perfectly for about 3 years.

About a month ago our internet signal became intermittent and dropped out frequently. The new 5G gateway was replaced, however the problem still persisted, even with a new gateway. We had no trouble for the first 3 years with the old LTE gateway it worked perfectly.

The shorter the wavelength of a frequency the less likely it is to travel through items and the more likely it is to bounce off of items.

I believe this is the reason for my intermittent signal. The new 5G frequencies are shorter in wavelength than the LTE frequencies, thus making them unable to travel through the thick canopy of leaves on the trees, like the LTE frequencies did.

My conclusion of T-Mobile internet, and any of the wireless internet services, is that since there's no physical cable running to the house so they feel there's no need to have technicians in the field to come to your home and do actual RF measurements.

It's basically a self-serve operation with minimal customer support.

So if it works at your location, fantastic, however if you have any issues with the RF signal,  you're just out of luck.

I can say it was good while it lasted. But until they can canvas an area with enough towers to overcome signal degradation at 5G frequencies, it's a hit or miss service.
