Check the interface's subnet first. The problem normally occurs if you use the static IP address for some of the devices... No issue with devices that uses a dynamic IP address (in this case, WIFI devices since it is rare for the user to use the static IP address on their smartphones when connecting wirelessly, for example). Different routers may use different subnets. For example, DLINK uses 192.168.0.x, ASUS uses 192.168.1.x, etc. Check your router's manual which subnets it uses. You can change this on the router-side or on the device-side...just make sure all devices and the router(s) use the same subnet. In your case, check your laptop's IP address matches the subnet used by your router if it is configured with a static IP address.
