No Internet Access R320 Unleashed

[lee_wolstencrof]

I have 2 x R320 unleashed access points set-up in a MESH network.  All of my devices are connecting fine and have internet access.
However, a windows 10 laptop will connect to the network but cannot get internet access & i noticed the AP isn't giving it an IP address.
Any idea's why this could be?

Thanks.
Lee.
