The Deco does have the malicious website filter that resides in the Antivirus which block sites according to the TrendMicro security database. So it may not block ads, in that you would use extensions like you mentioned.

@JRSmooth I run pi-hole on a separate old laptop.  It's a simple setup, so if you can futz your way around some basic linux it works great.  https://pi-hole.net/

I still have my router be the dhcp server and I set the primary DNS to be the pi-hole computer and the secondary to Cloudflare.  That way if there's ever a problem with the pi-hole server the other computers in the won't be affected.  All that's lost is the ad blocking.
