Trying to troubleshoot a WiFi issue with a Google router and two access points. When trying to log into the router with a PC/browser, all I get a message telling me to use the Home app on an Android device (phone). Well, that requires WiFi, which isn't working. The router is working using Ethernet. internet access, etc., all fine. But no WiFi connectivity. But apparently it's not possible to log into a Google router using ethernet?!?! How does one troubleshoot the thing if WiFi isn't working?
