One needs to establish whether the Wifi router is broadcasting an SSID signal when it's wireless, you can do this with a wireless analyses app installed on the PC or smartphone.

Once you have established that it is broadcasting a signal then the issue would be either the broadband is down. It has either failed to connect physically (router stats can establish this fact) or the TCP/IP layer has failed which is likely Sky/Openreach doing maintenance usually.
