No url for access

new install, two things are failing upon boot resulting in no ip address to connect to and the {dot}local addresses not to work

tried reinstalling same thing happens, anyone tell me how to fix it

TIA

DHCP turned on?

first few installs (just playing around) was working fine then I moved it to a different switch on my network and this started

now I cannot get a ip address after doingh a fresh install, same happens if I use a different pi

installing the pi os will get a ip address

Have you set a reservation?

I did but then I deleted it

You want your address to be repeatable and predictable. Start with a reservation and go from there.

I have to have a ip adddress to be able to do that
