Netgear M5 MR5100 and Consumer Cellular

I have a Netgear 5100 on Consumer Cellular.  I've been using it to allow telephone use on WiFi within a metal building where the signal for cellular use is weak by placing it and external antennas in a window.  It also provides good WiFi data to the phones in the building.

Lately it's been dropping offline so I added an APN mimicking those in place but with the name "reseller" in both name slots.  I also put the Wifi to 2.4 GHz only to allow the 5 GHz to be used to enhance LTE speed on the cellular connection.  (Something I don't understand about a 5G enhanced, but slower than 5G connection to the cellular network)

The problem seems to be fixed as it no longer hunts among US Cellular, Verizon and T-Mobile.

Would like to "fix" the network as AT&T as well as a future trouble-shooting tactic but I can not find manual selection of a network.  Just a hint that it exists.

Too early to tell but so far it is good.
