There could be several reasons for you to block a particular device from using your Sky router’s network. The reason might be anything, but the following procedure has to be performed if you wish to have the Sky router all to yourself. This procedure might take a few minutes to complete:
On your computer, open the default web browser. Then, type 192.168.0.1 in the address bar of the browser.
You will now be taken to the Sky settings page. You will find a pop-up that asks you for the username and password. Your default username will be admin and your password will be sky.
After you have entered your credentials, click the Advanced tab.
Under Advanced, click the LAN IP Setup option.
Scroll down to the Address Reservation section and then click on the Add button.
When you click on the Add button, a table of all the devices connected to your home network will be displayed on your screen.
Note down the IP address of the device that you want to block from accessing your Wi-Fi network.
Click on the Security tab and enter your password when prompted.
Directly below Security, you will see many options, including Firewall Rules. Now, select the Firewall Rules option.
Next, scroll down the page until you see the Outbound services section. In this section, click on the Add button.
You will now be taken to a new page that consists of a mixture of letters and numbers. Under IPv4 Settings, you have to change the drop-down boxes to the options given below:
In the Service field, the setting has to be Any(ALL)
In the Action field, the selected option should be BLOCK always
In the Access from field, you have to choose the Single address option.
Next to the Source IPv4 LAN start address field, you have to enter the IP address of the device that you wish to block.
Finally, click on the pink Apply button.
In case you want to undo the procedure explained above, you just have to navigate back to the Firewall Rules page and then delete the new listing from the Outbound services box.
You have now successfully blocked the owner of that particular device from accessing your Sky router.
