Also, owners or routers able to run OpenWRT (which is actively maintained and in great shape since the merge with LEDE), you have access to several packages providing the same technical solution (DNS-based blocking). As far as I know, the most common and maintained is https://github.com/openwrt/packages/tree/master/net/adblock/... .

Super easy to install, full-featured, lots of lists to pick from, auto-updates lists, no need for an additional device, and you will benefit from router features produced by the openwrt community and maybe unavailable in your router proprietary firmware. Much recommended.

If that sounds attractive and it sounds like a good opportunity to change your crumbling unpatched router, the question "what's today's good cheap router running openwrt without trouble?" is frequently answered by https://www.reddit.com/r/openwrt/ :) .

Curious about anyone's experience with adblock for OpenWRT.

I use Pi-hole now, and it works great. The one feature that I use quite a lot is the ability to disable it for a short period of time -- when I'm shopping for something, Google ads are sometimes actually useful!

I'd say I use that feature about once a month. That's the sum value of advertising for me.
