Cannot connect to temporary network during Orbi setup

technically it’s an old install, but for some reason it stopped working so I reset it. I tried wiring my PC into it, but there was no internet connection. Like I said, this is during setup. The modem is an EU2251 from Spectrum, and the router’s firmware version is 2.7.3.22. I already checked for updates and such.
The weird thing is, even after manually resetting the router it retained the old network settings. After replacing the router to where it was and reconnecting it because I had given up, the app says everything is connected and online. That being said, I can’t pull an ethernet connection from a satellite in a different room (which was the original problem). It’s pretty convoluted and I’m not entirely sure what’s going on here, but that’s what I can make of it.
