Device Settings That Can Interfere With Your Router VPN

Dave · Oct 6, 2026 ·

If your router VPN is connected and working on other devices but one phone, tablet, computer, or streaming device shows the wrong IP address, wrong location, cannot access certain websites, or behaves differently, check the affected device before changing the router.

VPN applications, privacy features, custom DNS settings, antivirus software, firewalls, browser settings, and corporate security software can all change how traffic is handled directly on a device.

This guide applies to all FlashRouter types and VPN providers.

Start Here: Is the Problem the Router or One Device?

Before changing your router VPN configuration, compare the affected device with another device connected to the same FlashRouter.

If several devices show the correct VPN IP and location while only one device does not, the router VPN is already demonstrating that it can route traffic through the VPN.

Focus troubleshooting on the affected device.

If every device connected to the FlashRouter has the same VPN problem, continue with router-level VPN troubleshooting instead.

Privacy Hero users should also check the Privacy Hero dashboard. If the VPN itself displays Failed, Disconnected, Connecting, or a timeout error, troubleshoot that connection before changing device settings.

Disconnect VPN Applications Running on the Device

Do not run a VPN application directly on the device while troubleshooting a VPN running on your router.

This includes applications from NordVPN, ExpressVPN, Surfshark, Proton VPN, IPVanish, Private Internet Access, Mullvad, corporate VPN providers, and other VPN services.

If both the router VPN and device VPN are active, the device VPN can take control of that device’s traffic after it passes through the router.

This can cause:

An unexpected public IP address.
An unexpected VPN location.
Websites or applications not loading.
Streaming region problems.
DNS problems.
Slow or unstable connections.
One device behaving differently from other devices on the same router.

Disconnect the VPN application completely before testing the router VPN.

Closing the VPN app window may not disconnect the VPN. Confirm in the application or device network settings that the device-level VPN is actually disconnected.

iPhone and iPad: Check Private Relay and Limit IP Address Tracking

Apple devices include privacy features that can change how supported internet traffic is handled and make router VPN testing more difficult.

Limit IP Address Tracking

To temporarily disable Limit IP Address Tracking for your FlashRouter WiFi network:

Open Settings.
Select Wi-Fi.
Tap the information button next to the FlashRouter WiFi network.
Find Limit IP Address Tracking.
Turn it Off.
Disconnect from WiFi and reconnect.
Test the connection again.

This setting is configured per WiFi network, so make sure you are changing it for the FlashRouter network being tested.

iCloud Private Relay

iCloud Private Relay can also alter IP address visibility for supported traffic.

For troubleshooting:

Open Settings.
Tap your Apple Account/name.
Select iCloud.
Select Private Relay.
Temporarily turn Private Relay Off.
Reconnect to the FlashRouter.
Test the IP address and connection again.

These settings can be restored after testing.

Android: Check Private DNS and Always-On VPN

Android devices can have DNS and VPN settings that operate independently of the router.

Private DNS

Android Private DNS can send DNS requests to a selected DNS provider instead of relying solely on the DNS configuration supplied by the router.

If you are troubleshooting DNS, website access, streaming, filtering, or location behavior:

Open Settings.
Select Network & internet.
Select Private DNS.
Temporarily select Off.
Save the setting.
Reconnect to the FlashRouter WiFi.
Test again.

Android menus vary by manufacturer and Android version. Search the device Settings for Private DNS if necessary.

Always-On VPN

An Android VPN application can be configured to automatically reconnect even after you believe the VPN has been disconnected.

Open Settings.
Select Network & internet.
Select VPN.
Select the configured VPN.
Disable Always-on VPN while testing.
Check whether Block connections without VPN is enabled and temporarily disable it if necessary for testing.

Then reconnect to the FlashRouter and test the router VPN again.

Check Antivirus, Firewall, Browser, and Work Security Settings

If the problem affects a computer or only occurs in one browser, check for software that modifies network traffic directly on the device.

Antivirus and Internet Security Software

Security applications may include network features such as:

Web Protection.
Safe Browsing or Secure Web.
Network Protection.
DNS Protection.
HTTPS scanning.
Tracking protection.
Built-in VPN services.
Firewall controls.

Temporarily disable the relevant network protection feature and test again. You do not normally need to disable the entire antivirus product.

Third-Party Firewalls

A third-party firewall can block applications, DNS requests, VPN-related traffic, or specific network interfaces.

Temporarily disable the firewall and test the connection. If the problem disappears, re-enable the firewall and review its network rules.

Browser VPN, Proxy, and Secure DNS

Browsers and browser extensions can also use their own:

VPN services.
Proxy connections.
Secure DNS or DNS-over-HTTPS.
Privacy or filtering extensions.
Location-changing extensions.

If the problem occurs only in one browser, test another browser without extensions or custom networking settings.

Work and Corporate Devices

Company-managed computers and mobile devices may use corporate VPN clients, DNS filtering, web filtering, endpoint security, device-management profiles, or zero-trust networking software.

These systems may intentionally override the local router’s network behavior.

If a personal device works correctly on the same FlashRouter while a company-managed device does not, the company security configuration may be responsible.

Run a Clean Router VPN Test

For the cleanest test, temporarily remove device-level networking variables and let the FlashRouter VPN handle the connection.

FlashRouter VPN: On
Device VPN: Off
iCloud Private Relay: Off while testing
Limit IP Address Tracking: Off while testing
Android Private DNS/custom DNS: Off while testing
Always-On VPN: Off while testing
Third-party network filtering: Off while testing

Then:

Disconnect the affected device from WiFi.
Reconnect it to the FlashRouter.
Open a fresh private/incognito browser window.
Check the device’s public IP address and location.
Compare the result with another device connected to the same FlashRouter.

If the second device shows the correct VPN IP but the affected device does not, continue troubleshooting settings or software on the affected device.

If all devices show the same incorrect IP address or all devices fail to use the VPN, continue with router-level VPN troubleshooting.

Privacy Hero VPN Connected but Device Still Shows the Wrong IP?

Privacy Hero provides device-level VPN controls. Make sure the affected device is actually assigned to use the VPN.

Open app.privacyhero.com.
Open the Devices section.
Select the affected device.
Confirm VPN protection is enabled for that device.
Disconnect any VPN application running directly on the device.
Test the public IP address again.

If other Privacy Hero devices show the correct VPN IP and only one device remains incorrect, continue with the device-level checks above.

Flint/Slate GL.iNet Guest Network Setup

TeamFlashRouters · Apr 20, 2023 ·

Follow this guide to setup a Guest Network on your GL.iNet FlashRouter. Devices connected to the guest network will be on a separate subnet and will not have access to the router settings or be able to talk to devices on the main network.

1. Connect your computer, phone, or tablet to the GL.iNet router via wireless (FlashRouter24 / FlashRouter50) or via ethernet cable to one of the LAN ports on the router.

The FlashRouter WiFi password is printed on the sheet that came with the router and is set to Wireless#[First 5 characters of your router MAC]. The router MAC can be found on the bottom of your router if you cannot locate the sheet. For e.g. if your MAC is 1459C07E70A8 then your WiFi password is Wireless#1459C

Be sure to capitalize the W.

2. Once connected via wireless or ethernet on your device open your browser and go to 192.168.8.1

3. Enter openwrt as the admin password to access the GL.iNet firmware settings.

4. Click Wireless.

5. Click 5GHz Guest Wi-Fi or 2.4GHz Guest Wi-Fi.

6. Click Modify.

7. Set the Enable Wi-Fi toggle to the ON position.

8. Change the Wi-Fi Name (SSID) and Wi-Fi Password fields to what you want to use. The SSID should be unique and NOT a duplicate of an existing network. Click Apply.

9. Connect your devices to the new guest wireless network.
