I want to block ads and trackers on the whole home network. I’ve been using adblockers and trackers for years now; I currently have a Raspberry Pi. I was thinking of setting up Pi-Hole with AdGuard. Any other suggestions are welcome. (I can’t use a custom router, because my ISP doesn’t allow it)
Put their router into modem mode and daisy chain your own router. Look up its labels and find the original manufacture for manuals. Watch out for name changes and mergers. ISPs do not manufacture routers. They buy them from companies, change a few logos and lend them to you.
You can also use the DMZ setting for your router depending on the software on the device from your ISP. DMZ means all traffic is forwarded that hits the device.
