WAC 124 No internet

I set up my WAC124 in Access point mode absolutely fine. Next day I just turned it off and on to try and get a google home working with it. Now, it is not detecting the internet cable in the back. I have tried the cable directly into my PC and it works fine. I did a reset on the WAC124 to try setting it up again. No luck. Through the set up it tries to detect an internet connection and it just cannot connect. I managed to get into the router set up at routerlogin.net and it tries to find the internet connection and stays it is a static ip address. When I set up the Access point I made sure it was on dynamic ip address. I have tried getting the ip/dns addresses from my sky router to set it up manually but not luck

Just don't understand how it could have just lost the connection? 

Any help would be apprecieted?
