WN2000RPT no mywifiext access by ethernet, cannot access WiFi

It appears that the issue might have resolved itself since my last attempt. But to share my experience for other users, I was eventually able to login via Microsoft Edge. I was able to access the extender by ethernet, referring to it by it's IP address, as assigned by my modem/router. I used the pre-existing password to connect to the WiFi, changed it to something a little more memorable, and accessibility by WiFi appears to be fine now. Strangely enough, during the WiFi reconfiguration by Ethernet, I was asked to connect to the extender's WiFi, did so, and then it attempted to redirect me to www.mywifiext.net/cgi-bin/index.html which gives me a 404 error (Page not found.) I removed the ethernet cable and tried to access this with just the wifi connected, same result. Not that it matters. All appears fine. I'm yet to test other devices.

Thank you for your reply. I can't give you Kudos because I keep getting an Authentication Failed error. Most likely it's my browser security measures.
