my airport stopped working when i changed its location within the same network (wired)

the weird thing is that all Ive done is move its pysical location....my house has ethernet ports in every room all running through a common upstream router which in turn is connected to a dsl modem. At this point Ive hard reset the AX back to factory settings....now the AX utility sees the AX but shows me that it has a total of 3 problems. 1) Internet connection...2) no DNS servers...3) default settings. When I highlight "default settings" the info reads "this AX base station has default settings. You should configure it to connect to the internet, secure the wireless network, and provide a password. I assume that if I correct this, the other 2 troubles should take care of themselves. At the bottom of the page there are buttons that say...help, revert, update and a drop down menu that says default settings, recovered settings, create profile, edit profiles. not sure where to go from here. thaks for taking the time to help me.

I have checked the connection, and it is ok....when I plug my laptop in at that connection point, I can access the internet. I have the same trouble at other ethernet ports as well...I think I need to set the AX up as if I just bought it because Ive reset it....Im just not sure how to do this from the screen that I am seeing.
