How to use NUFRONT EUHT terminal Access equipment? Say you don't need to plug in the cable to have WIFI, but can't connect? What to do?

It's not that I can't use it. I can use it. I started with 12345678. Enter 10.29.200.1 to go to the management page. But make sure the router works. I'm the owner of the second floor. I hope it helps.
