After going in circles looking for a solution to the “security” concerns of Chrome and Edge that result in not allowing a 192.168.0.1 login, I finally tried old Internet Explorer ("C:\Program Files\internet explorer\iexplore.exe") and Voila! 

Apparently, Chrome/Edge substitute https in place of http - it’s a “feature.”

(Microsoft may discontinue Internet Explorer in future but some other browsers also may work)
