If you changed it on the HUB it will use DHCP, a router can't allocate a 'static' address it can only allocate a 'reserved' address still using DHCP to do so. I.e allocate a given MAC address the same IP address each time. If you want to allocate a static address you need to do it on the device itself as posted in message 2. Give the device an address outside of the DHCP range of the hub.
Tried this but I cant see Sky Wireless Connector listed, just some other known devices and a few "unknowns"
