I have just recieved my AC750 extender today but when I navigate on Chrome to mywifiext webpage I do not get the screen I have seen in the tutorial with the New Extender Set up button.
What I get when the page loads is the screen in the attachment, any idea what I am doing wrong?
TIA
Model: EX3700|AC750 WiFi Range Extender Essentials Edition
Briefly, the idea is that "[www.]routerlogin.net" (or ".com", or "orbilogin.net", ...) should point to your own router, but that's true only if you use your own router for DNS name resolution. (Or, if the Netgear router can intercept your DNS queries.) Regardless, you should be able to get to the thing using its IP address, if you can determine (or guess) that. Normally, that would be something like "192.168.1.1" (for a plain router) or "192.168.0.1" (for a modem+router), but it could be different. ("10.0.0.1" is a typical alternate, for example.)
A new complication arises if your web browser uses "DNS over HTTPS" (and some real-world DNS server directly). In that case, those "routerlogin" names will typically take you to that misleading/useless Netgear error page. Specifying the IP address (instead of a "routerlogin" name) should work, but there are some exotic cases where you might need to disable "DNS over HTTPS" in your browser.
For an extender, you might look at an Attached Devices (or equivalent) report on your main router, to see if you can extract the IP address of the extender from that.
