It sounds like DHCP is not working. The next question is why.

One possibility is that you've plugged the computer into the routers WAN
port. If you are using the router as your border gateway, that won't be
possible, as your WAN port will already be occupied, but if you are
using it only as an access point, your WAN port may in fact be open.

Otherwise, I'd examine your router's DHCP configuration.

I don't understand why you needed to manually set the MAC. Did you mean IP?

You are working your way through all the things that DHCP would normally
set for you. If you get DHCP working correctly, all of these can be avoided.

If you can't get DHCP working for some reason, here's the official guide
for manually configuring a static IP on a wired connection through the GUI:
