Adguard Home Asus Merlin (Ultimate — 2025)

His fingers hovered over the keyboard. This was the risky part. Routers have tiny CPUs, limited RAM. AdGuard Home was a beast. It wanted to filter DNS for 50 devices, run a pretty web interface, and keep a query log.

He saw one query from his own phone: reddit.com . Allowed. Followed by: redditmedia.com . Allowed. Followed by: google-analytics.com . Blocked.

The web interface loaded. Dark theme. Graphs. He configured the router’s DHCP to hand out the router’s own IP as the DNS server. Every device on the network—smart bulb, doorbell, iPad, PlayStation—would now ask the router for permission to resolve a domain.

His wife said, “That weird pop-up is gone.” adguard home asus merlin

He laughed. Nice try.

Here is the story of how AdGuard Home found a home on an ASUS Merlin router.

He exhaled.

He added the OISD blocklist. Then the “No Tracking” list. Then the “Phishing Army” list.

Every device on Maple Street was screaming into the void: “What’s the IP for doubleclick.net? Where is taboola.com? Please, I need more ads!”

He never looked at a Raspberry Pi again. Asuswrt-Merlin and AdGuard Home had become the silent, tireless guardian of Maple Street—filtering the noise, blocking the trackers, and letting the family get back to what mattered: ignoring each other peacefully while streaming in 4K. His fingers hovered over the keyboard

Months later, a neighbor asked, “Kevin, your internet seems so clean. No lag. No ads on Hulu. What’s your secret?”

“It’s not the router,” he said. “It’s the wizard inside.”

That night, Kevin downloaded the latest Asuswrt-Merlin build. Flashing the router felt like performing surgery on a patient who was awake—one wrong click, and the family’s Netflix dies. AdGuard Home was a beast

Kevin just smiled and poured his coffee. He pulled up the AdGuard Home dashboard on his phone. The query log was a battlefield. 45% blocked. The router’s CPU was at 12%.

Kevin knew the culprit. Not a virus. Greed.
