Most parents know their router has parental controls. The vast majority stop at the basic "block adult content" checkbox and never dig deeper, which is a missed opportunity. A modern Wi-Fi router is the single most powerful piece of online safety equipment in a household, and the features baked into even an entry-level model go far beyond simple content filtering. All major broadband providers now offer free parental controls that can apply content filtering and block unsuitable websites, but the default settings are usually the bare minimum. In the same way parental controls are now arriving for AI tools like ChatGPT, routers already have a full suite of tools sitting there waiting to be used, and there are numerous clever ways to put them to work.
