Wi-Fi does not have an IP address

[JoshJ]

I am trying to connect to my downstairs neighbours wifi (they are away & gave us the password).
My iPhone is connected fine but my mac refuses to connect even though it shows a full signal in the the list of available connections. When I go into network preferences & select wifi it says "Wi-Fi does not have an IP address and cannot connect to the Internet."

Have tried deleting and recreating the wifi via Network settings and the Keychain app but nothing has worked yet. Have tried resetting the location in Network preferences also.

Any suggestions?

Generous neighbors might have given the password to everyone else and the router has likely reached it's device limit.

Any suggestions?

Set up your own WiFi?

Can you contact your neighbor downstairs?
