Common Causes of the Issue

AdGuard on Android, when not functioning as expected, can be frustrating. Understanding the common culprits behind these issues is the first step toward regaining your secure and ad-free browsing experience. This section delves into the frequently encountered problems that may be preventing AdGuard from working correctly, offering insights into how to identify and resolve them.

Incorrect DNS Server Addresses

The Domain Name System (DNS) acts as the internet’s phonebook, translating website names (like example.com) into numerical IP addresses that your device understands. When AdGuard isn’t filtering properly, the DNS settings are often the source of the problem.AdGuard relies on the correct DNS server addresses to filter your internet traffic. If these addresses are incorrect, AdGuard won’t be able to redirect your traffic through its filtering servers.

This is like trying to send a letter with the wrong postal code; it simply won’t reach its destination.* Incorrect DNS configuration: Ensure that AdGuard’s DNS settings are properly configured. Check the app’s settings for the DNS server addresses and verify that they are correct. These addresses typically begin with numbers like 94.140.14.14 or 94.140.15.15 (AdGuard’s default servers) or other valid DNS server addresses you’ve chosen.

Conflict with system-level DNS

Some Android devices allow for system-level DNS configuration. These settings might override or conflict with AdGuard’s settings. To resolve this, disable the system-level DNS or ensure it’s not interfering with AdGuard’s operation.

DNS leaks

Occasionally, even with AdGuard enabled, your device might still be using your ISP’s DNS servers, leading to DNS leaks. This means your browsing activity is not being filtered by AdGuard.

To prevent DNS leaks, it is crucial to ensure that all DNS queries are routed through AdGuard’s servers.

You can test for DNS leaks using online tools. If leaks are detected, review and adjust your DNS settings within AdGuard.

Potential Impact of Firewall Settings on AdGuard’s Functionality

Firewalls, designed to protect your device from unauthorized network access, can sometimes interfere with AdGuard’s operation. If the firewall is overly restrictive, it may block AdGuard’s ability to filter internet traffic.Firewalls operate by examining network traffic and deciding whether to allow or block it. AdGuard functions by intercepting and modifying network requests, and if the firewall blocks these requests, AdGuard will not work.* Firewall blocking AdGuard’s access: Some firewalls might mistakenly identify AdGuard as a threat and block its access to the internet.

Review your firewall settings and ensure that AdGuard is permitted to access the network. Add AdGuard to the firewall’s “allowed” list.

Conflict with other security apps

Other security applications, such as VPNs or other ad blockers, can also interfere with AdGuard. These applications may compete for network access or block each other’s functions. Disable or uninstall conflicting applications to see if it resolves the issue.

Incorrect firewall configuration

Ensure that your firewall isn’t configured to block specific ports or protocols that AdGuard uses. AdGuard relies on standard internet protocols, and blocking these will prevent it from working correctly. Examine the firewall’s rules and ensure they are not too restrictive.

Role of Mobile Data or Wi-Fi Network Configurations in Causing the Issue

The network you are connected to—whether mobile data or Wi-Fi—can also influence AdGuard’s functionality. Network-specific settings and configurations can create problems.Your network settings determine how your device connects to the internet. If these settings are misconfigured, it can prevent AdGuard from operating correctly. This can range from incorrect proxy settings to restrictions imposed by your mobile carrier or Wi-Fi network administrator.* Mobile data restrictions: Some mobile carriers may restrict the use of VPNs or DNS settings that AdGuard utilizes.

Check with your mobile provider to see if they impose any such restrictions.

Wi-Fi network restrictions

Public Wi-Fi networks or those with strict network policies might block or interfere with AdGuard. These networks may use captive portals or other mechanisms to control internet access, which can prevent AdGuard from functioning.

Proxy settings

If your device is configured to use a proxy server, it could interfere with AdGuard’s operation. AdGuard might not be able to intercept and filter traffic correctly if it’s routed through a proxy server. Disable the proxy settings or configure AdGuard to work with the proxy.

For instance, if you are using a public Wi-Fi network at a coffee shop, the network administrator might have implemented filtering or blocking rules that conflict with AdGuard’s functions.

Network-specific DNS settings

Some Wi-Fi networks may enforce their own DNS settings. These settings can override AdGuard’s DNS settings. In this situation, you may need to disable the Wi-Fi network’s DNS settings or configure AdGuard to work with those settings.

AdGuard App Specific Problems

Sometimes, the issue isn’t with your network or the fundamental principles of DNS; it’s a hiccup within the AdGuard app itself. Let’s delve into some troubleshooting steps specifically targeting the application. Think of it as performing a digital health checkup on your AdGuard.

DNS Filtering: Some routers have built-in DNS filtering or parental control features. These features may override AdGuard’s DNS settings, preventing it from filtering ads and tracking. Check your router’s configuration to see if any DNS filtering is enabled and, if so, disable it or configure it to allow AdGuard’s DNS servers.
Firewall Settings: Routers often have firewalls that can block specific types of traffic. Ensure that the firewall isn’t blocking the ports used by AdGuard. Check your router’s manual for instructions on how to adjust firewall settings.
MAC Address Filtering: MAC address filtering allows you to restrict which devices can connect to your Wi-Fi network. If your device’s MAC address is not on the allowed list, it will not be able to connect to the internet, and thus, AdGuard will not work. Verify that your device’s MAC address is permitted in the router’s settings.
Content Filtering/Parental Controls: Many routers include content filtering or parental control features. These can sometimes interfere with AdGuard’s ability to filter ads and trackers. If these features are enabled, temporarily disable them to see if it resolves the issue. If it does, you may need to adjust the settings to allow AdGuard’s functionality.
Router Firmware: Outdated router firmware can cause various connectivity problems. Ensure your router’s firmware is up to date by checking for updates in the router’s settings.

Accessing your router’s settings usually involves typing its IP address (often 192.168.1.1 or 192.168.0.1) into a web browser on a device connected to the network. You will then need to enter your router’s username and password. Consult your router’s manual for specific instructions on accessing and configuring its settings.

Diagnosing Problems Related to DNS Resolution at the Network Level

DNS (Domain Name System) resolution is the process of translating domain names (like google.com) into IP addresses, which are necessary for your device to communicate with websites and other online services. Problems with DNS resolution can manifest as slow loading times, website errors, or AdGuard’s inability to filter content effectively.Here are methods to diagnose DNS resolution problems:

Checking DNS Servers: Ensure your Android device is using the correct DNS servers. If you are using AdGuard, the device should be configured to use AdGuard’s DNS servers (e.g., 94.140.14.14 and 94.140.15.15). You can typically configure DNS settings in your Wi-Fi network settings or in AdGuard’s app settings.
Flushing DNS Cache: The DNS cache stores previously resolved domain names to speed up future lookups. Sometimes, this cache can become corrupted, leading to incorrect resolutions. You can flush the DNS cache on your Android device by using the following methods:
- Using AdGuard: In the AdGuard app, go to “Settings” -> “Advanced” -> “Low-level settings” and then tap “Clear DNS cache”.
- Using ADB (Android Debug Bridge): Connect your Android device to your computer via USB, enable USB debugging, and use the following ADB command:
  
  adb shell pm clear com.android.providers.settings
  
  This command clears the settings app’s cache, which also clears the DNS cache.
Using DNS Lookup Tools: Use online DNS lookup tools or apps to check the DNS resolution for specific domains. These tools will show you the IP address associated with a domain name and the DNS servers being used. This can help you identify if the correct DNS servers are being used and if there are any resolution problems.
Testing with Different DNS Servers: Try switching to different DNS servers (e.g., Google’s public DNS at 8.8.8.8 and 8.8.4.4, Cloudflare’s DNS at 1.1.1.1 and 1.0.0.1) to see if it resolves the issue. This can help you determine if the problem is specific to the DNS servers you are currently using. If a different DNS server works, the original server might be experiencing an outage or configuration issue.
Network Monitoring Tools: Use network monitoring tools (e.g., Wireshark on a computer connected to the same network) to analyze network traffic and identify DNS-related errors. These tools can capture and analyze network packets, providing detailed information about DNS queries and responses.

By systematically investigating these aspects of network connectivity, you can pinpoint the source of the problem and implement effective solutions to restore AdGuard’s functionality.

You’ll then be prompted for a username and password; if you haven’t changed them, these are often “admin” and “password” or left blank (but

definitely* change them for security!).

Once logged in, look for a section related to “Network,” “Internet,” “WAN,” or “DNS.” This is where the magic happens. Here’s a general guide:

Locate the DNS Settings: Within the router’s configuration, search for a DNS settings area. This might be a dedicated section or part of the WAN/Internet setup.
Choose Your DNS Servers: You’ll typically find fields for “Primary DNS” and “Secondary DNS.” This is where you’ll input the DNS server addresses. You can use AdGuard’s DNS servers, Google’s public DNS (8.8.8.8 and 8.8.4.4), Cloudflare’s (1.1.1.1 and 1.0.0.1), or any other provider you prefer. For AdGuard, use their default settings:

Primary DNS: 94.140.14.14

Secondary DNS: 94.140.15.15

Save Your Changes: After entering the DNS server addresses, save the settings. Your router will likely restart or require a reboot to apply the changes.
Test the Connection: After the router restarts, check if your Android device is using the new DNS servers. You can use a DNS leak test website or app on your Android to verify.

Router Settings Overriding Android DNS Settings

The reason your Android device might not be using the DNS servers you configured in AdGuard is that the router’s settings are taking precedence. When a device connects to a Wi-Fi network, it often automatically adopts the DNS servers specified by the router. This is because the router broadcasts the DNS server information as part of its DHCP (Dynamic Host Configuration Protocol) settings.

This means that even if you’ve set up AdGuard on your phone, the router can still be sending it instructions to use different DNS servers. The router, acting as a central authority, essentially overrules your Android’s direct DNS configurations.

Determining Router Interference with AdGuard

To see if your router is the problem, you need to check which DNS servers your Android device is

actually* using. Here’s how to do it

Check AdGuard’s Settings: First, ensure AdGuard is enabled on your Android device and that it’s configured to use the desired DNS servers. Double-check that you haven’t inadvertently disabled AdGuard or made a configuration error.
Use a DNS Leak Test: A DNS leak test website or app will reveal the DNS servers your device is currently using. There are many free options available; search for “DNS leak test” online. If the test shows DNS servers other than the ones you set in AdGuard, the router is likely the culprit. For example:

Scenario 1: AdGuard working as expected

AdGuard configured with: 94.140.14.14, 94.140.15.15

DNS Leak Test Results: 94.140.14.14, 94.140.15.15

Scenario 2: Router interfering

AdGuard configured with: 94.140.14.14, 94.140.15.15

Router configured with: Default ISP DNS servers

DNS Leak Test Results: ISP’s DNS servers (e.g., 1.2.3.4, 5.6.7.8)

Examine Router Configuration: If the DNS leak test reveals that your Android device is using DNS servers different from AdGuard’s settings, the next step is to examine your router’s DNS configuration. Log in to your router’s admin panel and verify which DNS servers are configured.
Temporarily Disable Router DNS (if possible): Some routers allow you to disable their DNS settings, effectively forcing connected devices to use the DNS servers they’re configured with directly. This can be a useful test. However, it’s not always available.
Reboot Devices: After making changes to your router’s DNS settings, reboot your Android device and the router. This ensures that both devices recognize and implement the new settings.
