WIFI working but laptops don’t recognise IP address

[Carly46]

We had a power cut and our laptops now won't connect the the WiFi stating no secure connection and that the IP address is not valid. The WIFI is working on all other devices and broadband test shows router, WiFi extender is working and all lights are green. I have unplugged and reset the router and WiFi extender but the laptops still won't connect. One laptop is a work laptop so I can't access any settings. I have called Sky yesterday and they got the connection up and running again on the laptops but it's stopped again today and after calling sky they said I would be contacted with 72 hours, however I work from home so I need to try and find a fix.
