@peterg: If you can access it by your phone or iPad on the same WiFi it can only be a laptop software issue. Sky routers can be problematic with allowing devices like printers to connect but if your laptop can connect to post here for example the problem has to be with the security software on the laptop. The router does not know what kind of device it is talking to. It can identify the type of chip-set used in the device but little else.
Over zealous security software apart from slowing your computer can be a real pain at times.
