Please advise; I've done a reflashing of latest firmware to RT-AC68W, then entering manual settings after factory reset. Now after rebooting the router, I cannot access it at 192.168.1.1; I cannot determine the 'updated IP address and port number' to reconnect to. I have the internet and can connect to the ethernet, and wifi network; but cannot pull up the GUI screen. Device discovery only shows the router at 192.168.1.1. I'm missing something that I've been able to do many times before. Ipconfig/release, renew; restarts; nothing is working. Thanks in advance.
