To configure Asus Router AdGuard DNS, log in to your router, open WAN → Internet Connection, disable automatic DNS, enter the AdGuard DNS server addresses, click Apply and restart your router. All devices connected to your Wi-Fi will automatically use AdGuard DNS for network-wide ad and tracker blocking.
If you’re tired of seeing ads on every website or want to improve your family’s online privacy, configuring AdGuard DNS on your Asus router is one of the easiest upgrades you can make.
Instead of installing ad blockers on every phone, laptop, tablet or smart TV, you only need to change the DNS settings once on your router. After that, every device connected to your Wi-Fi automatically benefits from network-level ad and tracker blocking.
Besides reducing advertisements, AdGuard DNS can also block phishing websites, malicious domains and online trackers before they even load. I switched to AdGuard DNS because I was tired of installing ad blockers on every new device at home. Once the router was configured, my phone, laptop, smart TV, and even my gaming console started using the same DNS automatically. It saved me a lot of time whenever I added a new device to the network.
In this guide, you’ll learn exactly how to configure AdGuard DNS on an Asus router, verify it’s working, troubleshoot common issues and understand how it compares to alternatives like Pi-hole and NextDNS.
What Is AdGuard DNS and How Does It Work?
If you’re wondering whether AdGuard DNS is worth using on an Asus router, the short answer is yes. It blocks many ads, trackers, phishing websites, and malicious domains for every device connected to your Wi-Fi, without requiring you to install software on each device.
Before changing your router settings, it’s helpful to understand what AdGuard DNS asus router actually does. Every time you visit a website, your device asks a DNS (Domain Name System) server to translate the website name into an IP address. Normally, your internet provider handles these DNS requests automatically.
AdGuard DNS replaces your ISP’s DNS with secure DNS servers that check each request before it reaches the website.
If the request belongs to:
- Advertising networks
- Tracking services
- Malware websites
- Phishing pages
- Scam domains
- AdGuard DNS blocks it immediately.
Because this happens before the website loads, many ads and trackers never reach your device. Think of it like a security guard standing at the entry of your network. Instead of letting every visitor enter, it checks whether they’re safe first.
How Network-Level DNS Blocking Differs from Browser Extensions
Many users already have browser extensions like AdBlock or uBlock Origin. While they reduce ads inside web browsers, they don’t protect your entire home network.
| Browser Ad Blocker | AdGuard DNS |
| Works only in browsers | Protects the whole network |
| Install on every device | Configure once on the router |
| Doesn’t help smart TVs | Works on TVs, consoles and IoT devices |
| Uses browser resources | Lightweight and automatic |
This makes network-wide ad blocking on an Asus router much easier to manage, especially if you have multiple devices at home.
What AdGuard DNS Blocks
AdGuard DNS is designed to improve both privacy and security.
It can block:
- Display advertisements
- Tracking scripts
- Malware domains
- Phishing websites
- Scam websites
- Analytics services
- Adult websites (using Family Protection DNS)
However, it’s important to understand its limitations. Because DNS filtering only blocks domain requests, it cannot block every advertisement.
For example:
- YouTube video ads
- Instagram sponsored posts
- Facebook feed ads
- Ads inside many mobile apps
are often served directly from the same servers as the content, making them impossible to block using DNS alone.
Why Set Up AdGuard DNS on Your Asus Router?
You could install an ad blocker on each device individually, but configuring the router offers several advantages.
1. Protect Every Connected Device Automatically
Once AdGuard DNS is configured on your Asus router, every connected device uses it automatically.
This includes:
- Android phones
- iPhones
- Windows PCs
- MacBooks
- Linux computers
- Smart TVs
- Apple TV
- Chromecast
- Fire TV Stick
- Xbox
- PlayStation
- Nintendo Switch
- Smart home devices
You don’t have to install extra software or repeat the setup for every new device.
2. No Apps or Browser Extensions Required
Many devices don’t even support ad blockers.
Examples include:
- Samsung Smart TVs
- LG TVs
- Roku
- Apple TV
- Gaming consoles
- Smart speakers
Because filtering happens at the router level, these devices benefit automatically. This is one of the biggest reasons many users choose AdGuard DNS over traditional browser extensions.
3. Faster Browsing and Reduced Data Usage
Blocking unnecessary advertising requests means websites often feel faster. Instead of downloading dozens of tracking scripts and advertising resources, your browser loads only the content you actually want.
In my own testing on an Asus RT-AX58U, several news websites became noticeably cleaner after switching to AdGuard DNS. It didn’t increase my internet speed, but pages loaded with fewer third-party requests, making browsing feel smoother.
4. Better Privacy
Advertising companies track users across thousands of websites. Many pages contact multiple analytics services before the content even appears on your screen. AdGuard DNS blocks many of these requests automatically, helping reduce online tracking without requiring additional software.
Before You Begin: Requirements & Compatibility
The good news is that most modern Asus routers support custom DNS settings. If your router allows you to edit WAN DNS settings, you can use AdGuard DNS.
Popular Compatible Models
| Router Series | Supported |
| RT-AX Series | Yes |
| RT-AC Series | Yes |
| ZenWiFi Series | Yes |
| ROG Gaming Routers | Yes |
| ExpertWiFi | Yes |
Some popular models include:
- Asus RT-AX58U
- Asus RT-AX86U
- Asus RT-AX88U
- Asus RT-AX3000
- Asus RT-AC68U
- Asus RT-AC86U
- ZenWiFi XT8
- ZenWiFi XD6
Tip: Update your router firmware before making DNS changes. New firmware often improves DNS stability and fixes compatibility issues.
From my experience: I tested this setup on an Asus RT-AX58U running the latest AsusWRT firmware, and the router accepted the AdGuard DNS settings without any extra configuration. I also tried it on an older RT-AC68U, where the setup worked just as well. The only difference was that the older router needed a restart before all connected devices started using the new DNS servers.
What You’ll Need
Before starting, make sure you have:
- Asus router administrator username and password
- Internet connection
- Router login address (usually router.asus.com or 192.168.50.1)
- AdGuard DNS server addresses
Having these ready makes the setup much quicker.
How to Find Your AdGuard DNS Server Addresses
AdGuard offers different DNS profiles depending on your needs. For most users, the Default DNS profile is the best choice because it blocks ads, trackers, phishing websites and malware without restricting normal browsing.
Default AdGuard DNS (Recommended)
| Server | IPv4 Address |
| Primary | 94.140.14.14 |
| Secondary | 94.140.15.15 |
If your ISP supports IPv6, you can also configure:
| Server | IPv6 Address |
| Primary | 2a10:50c0::ad1:ff |
| Secondary | 2a10:50c0::ad2:ff |
Family Protection DNS
If children regularly use your home network, Family Protection DNS is a better option. It includes everything in the default profile plus:
- Adult content blocking
- Safe Search enforcement
Additional protection against inappropriate websites
| Server | IPv4 Address |
| Primary | 94.140.14.15 |
| Secondary | 94.140.15.16 |
Which AdGuard DNS Should You Choose?
| User Type | Recommended Profile |
| Most home users | Default DNS |
| Families with children | Family Protection DNS |
Testing only Non-Filtering DNS
If you’re unsure, start with the Default DNS profile. You can always switch later without resetting your router.
Most users can complete this setup in less than 10 minutes, and you can always switch back to your ISP’s default DNS if you’re not happy with the results. There’s no permanent change, so it’s safe to try even if this is your first time changing router DNS settings.
Step-by-Step: Asus Router AdGuard DNS Setup Guide
Now it’s time to configure your Asus router. The process is almost equal across RT-AX, RT-AC, ZenWiFi and ROG routers.
Step 1: Log In to Your Asus Router
Connect your computer or phone to your Asus router.
Open a web browser and visit:
- http://router.asus.com
or
- http://192.168.50.1
If neither address works, try:
- http://192.168.1.1
- Enter your administrator username and password.
- Once logged in, you’ll see the Asus router dashboard.
Check our Asus Router Login Guide for more details.
Step 2: Open WAN Settings
From the left-hand menu, navigate to:
- Advanced Settings → WAN → Internet Connection
- Scroll down until you find the WAN DNS Setting section.
Step 3: Disable Automatic DNS
Locate the option:
- Connect to DNS Server Automatically
- Change it from Yes to No.
This allows you to manually enter custom DNS servers.
Step 4: Enter the AdGuard DNS Addresses
In the DNS fields, enter:
DNS Server 1
- 94.140.14.14
DNS Server 2
- 94.140.15.15
Double-check each number before saving. A single incorrect digit can prevent websites from loading.
Step 5: Configure IPv6 DNS (Optional)
If IPv6 is enabled on your network, go to:
- Advanced Settings → IPv6
- Enter the corresponding IPv6 AdGuard DNS addresses.
If your ISP doesn’t support IPv6, you can safely skip this step.
Step 6: Save the Settings
- Click Apply and wait for the router to save the new configuration. The process typically takes less than a minute.
Step 7: Restart Your Router
Although Asus routers apply DNS changes immediately after you click Apply, restarting the router ensures every connected device receives the new DNS settings.
You can restart the router in two ways:
- Click Reboot from the router dashboard.
- Turn the router off, wait 30 seconds and turn it back on.
- Once the router is back online, reconnect your devices to the Wi-Fi network.
Pro Tip: If some devices still use the old DNS after restarting the router, simply disconnect and reconnect them to Wi-Fi or restart the device.
How to Confirm AdGuard DNS Is Working
Changing the asus dns settings adguard doesn’t guarantee your router is using them correctly. It’s constantly a good idea to verify the setup.
Method 1: Use AdGuard’s DNS Test Page
The easiest way is to visit AdGuard’s DNS test page from any connected device. If everything is configured appropriately, you’ll see a confirmation that your network is using AdGuard DNS. If it shows your ISP’s DNS or another provider, review your router settings and try again.
Method 2: Run a DNS Leak Test
A DNS leak test shows which DNS servers your device is actually using. If the results display your ISP instead of AdGuard, your router or another device may be overriding the custom DNS settings.
This test is especially useful if you’re using:
- VPN software
- DNS over HTTPS (DoH)
- Private DNS on Android
- ISP modem-router combinations
Method 3: Test Multiple Devices
Don’t check just one device.
Test at least:
- Windows PC or Mac
- Android phone
- iPhone
- Smart TV
If all devices report AdGuard DNS, your setup is working correctly across the network.
Setting Up AdGuard DNS on Asus AiMesh Networks
If your home uses Asus AiMesh, the process is even easier. You only need to configure AdGuard DNS on the main AiMesh router. The satellite nodes automatically inherit those settings.
Best Practices for AiMesh
- Configure DNS only on the main router.
- Restart all AiMesh nodes after changing DNS.
- Allow 5–10 minutes for synchronization.
- If one node still uses the old DNS, restart that node manually.
Check our Asus AiMesh Setup Guide for further information.
Troubleshooting Common AdGuard DNS Setup Issues
Most problems are easy to fix. Here are the ones users encounter most often.
Websites Not Loading
If websites stop loading after changing DNS:
- Check the DNS addresses for typing mistakes.
- Restart your router.
- Flush your device’s DNS cache.
- Make sure Connect to DNS Server Automatically is set to No.
If the issue continues, temporarily switch back to automatic DNS to confirm the problem is related to DNS settings.
Some Ads Are Still Showing
This is completely normal. AdGuard DNS blocks many advertising domains, but it cannot block ads that come directly from the same server as the content.
Examples include:
- YouTube video ads
- Instagram sponsored posts
- Facebook feed ads
- Ads inside many mobile apps
For maximum ad blocking, you can combine AdGuard DNS with a browser extension like Asus router Ad Blocker or uBlock Origin.
DNS Settings Keep Reverting
If your custom DNS disappears after restarting the router:
- Ensure Connect to DNS Server Automatically is disabled.
- Update your router firmware.
- Save the settings before exiting.
- Restart the router after applying changes.
If the issue still occurs, back up your configuration, reset the router and configure it again.
ISP Router Is Overriding DNS
Some internet providers force their own DNS servers through the modem.
Common solutions include:
- Enable Bridge Mode on the ISP modem.
- Use the Asus router as your main router.
- Contact your ISP to ask if custom DNS is supported.
- AdGuard DNS vs Other DNS-Level Ad Blockers
During testing, I always recommend verifying the DNS change using both AdGuard’s DNS test page and a DNS leak test. In some cases, devices continue using cached DNS settings until they reconnect to the network or restart, so checking the results helps confirm the setup adguard dns router is working correctly.
