Block Google DNS on Linksys Routers
Step 1: Access the web-based setup page of your router (probably by going to 192.168.1.1, or 192.168.0.1 or 192.168.2.1). Default username is empty and the default password is admin. If that won't work, try admin as both the username and password. Step 2: Start by applying the playmoTV DNS on your router. In the Basic Setup sub-tab scroll down to Network Address Server Settings (DHCP), and enable the DHCP Server. Then apply the playmoTV DNS for your connection. You can find a list of our DNS servers by going to your user dashboard. Hit Save Settings and continue.
Step 3: On the Setup page, click Advanced Routing sub-tab
Step 4: Now, for the real deal: Step 5.1. Under Static Routing enter Route Name (you have to do three routes so name them something like "blockgoogle1" and then "blockgoogle2" and so forth. Step 5.2. For the Destination IP enter 188.8.131.52. Step 5.3. For the Subnet Mask enter 255.255.255.255 Step 5.4. For the Gateway enter the router's IP address (the address you use to access the router web utility).
Step 5.6 . Press Apply / Save Settings. Now repeat steps 5.1-5.6 for the Google's secondary DNS server: 184.108.40.206
Step 6: Save Settings, and ensure that everything has been entered by clicking Show Routing Table.
Step 7: Restart your router, and then you're good to go.
