Catalina 10.5 Self-Assigned IP Wi-Fi

[Carti718]

Please Help! Tried a few ways to fix issue and none have worked. Tried Renewing DHCP Lease and tried to check settings but all are good. I tried making a new location for my WiFi and did not work. I tried to delete certain folders in my Macintosh HD under Library>Preferences > System Configuration> and then delete airport preferences and network interface. All the help I can get would be greatly appreciated. I am stumped

What are you using for a router and a modem? Did this just start happening out of the blue, or did it happen after a macOS update?

It happened out of the blue, I have been using the same router on this iMac for at least an year. I haven’t updated the IOS because of my programs.

Okay. What router? Are you able to try connecting the iMac to Ethernet to see if you are able to get an IP address?
