Can the laptop see any other wireless networks? If not it would be worth checking that the wireless is turned on.
What laptop is it? Are you using Windows 10.
I would update the Laptop's wifi adapter's drivers from the adapter's manufacturer's website.
I would check the adapter's IPV4 properties and check that the obtain IP address and DNS addresses are set to automatic.
Try setting the hub to use WPA2 with AES security, as some devices do not handle WPA auto very well.
Thanks all for your advice,
The problem resolved itself. After 10 days of not being able to see the network, it just appeared. So all sorted!
