Log in to the router and select ADVANCED > Security > Block Sites, then choose either 'Always' to block continuously or 'Per Schedule' to block based on a set schedule. Enter the keyword or domain name you want to block in the provided field and click Add Keyword — the keyword list supports up to 32 entries. Click the Apply button to activate keyword blocking.
