EX3700 Range Extender - after reset cannot get mywifiest.net to work

[DeathMark72]

HELP! I had to get new equipment (modem & router from Spectrum) for my home and after getting that set up I tried to update the new network/password in my at that time working EX3700. I tried doing this before factory resetting it and I was able on MY_WIFI_EXT.NET  to get through the screen where it scans and detects the available networks and it found them. But I couldn't get farther without doing a factory reset so I did that. Following the steps in the instruction manual, I then went to MY_WIFI_EXT.NET and each time (at least 5) when I got to the scanning for networks screen, it would scan for about 20 seconds and then send me to the unhappy square saying it can't load that website. What should I do next?

A couple things you can try. 

1. try hardwiring a pc/laptop into the extender to set it up. Disable the wifi on the pc/laptop so it doesn't default back to that connection

2. try a different browser. i've had luck with firefox working when others wouldnt

3. clear cookies/cache on the current pc.
