Yes - the point is it is my own Sky Wireless Connector which the router "Attached Devices" shows as being connected (same MAC address in both the logs and the attached devices). My Sky box is working and the network settings page on there show that it is connected to my network. The Sky box and my router both show the same IP.
For some reason the Sky Wireless Connector is continually doing something that the router is blocking. I just wondered what is happening.
e.g. - I cleared the log earlier and this is an extract from the log as it is now:-
