The other day I came home and all my wireless devices would not connect to the internet.   They connected to the ssid but used ip address 192.168.10.1 verses my old address 192.168.0.1.  The router was transmitting the 2nd address so not sure why all our ipads selected that ip address.   Maybe a separate issue?

So after an hour of trying to fix I just set my router new default DNS to 192.168.10.1 and it worked.  However after 3 hours the wifi did not work any more.  I rebooted my router and it worked again.    Same thing happed over night this time.  In the AM no wifi but the lan worked perfect and never went out.   I remooted and wifi worked fine for about 12 hours this time.  Same thing happens over and over.
