I'd like to stop advertisements and other ad-related connections across my Wi-Fi network so I don't have to install an ad-blocking app on every device. Ideally, I want a router- or network-level solution that blocks as much advertising as possible for phones, computers, smart TVs, and other devices. What setup would you recommend, and what limitations should I expect?

DNS filtering makes a noticeable difference, but it can’t block everything. Services such as YouTube often deliver ads from the same domains as regular content, so DNS rules can’t reliably separate them. Browsers and some apps may still need their own content-blocking tools.
A network-wide DNS blocker such as Pi-hole or AdGuard Home is a good starting point. You can run one on a small server, NAS, or another always-on device and configure your router to use it as the network’s DNS server. It will block many known advertising and tracking domains for all connected devices.
If your router supports custom rules, you can use ad-blocking domain lists or hosts-file entries, but the results vary. Some websites serve ads from their primary domain, and devices may bypass your chosen DNS using encrypted DNS services. More advanced setups redirect DNS traffic back to your filter and block common DNS-over-HTTPS endpoints, though that requires extra router configuration.
Thanks, I’ll look into setting up one of those on my network.
