Troubleshooting Guide
DNS Jumper doesn't change DNS settings
Solution: Run DNS Jumper as an administrator. Right-click the executable and select "Run as administrator".
This is the most common issue and usually resolves the problem immediately.
High DNS resolve times or slow performance
Solution: Add DNS Jumper to your antivirus exclusion list. Some antivirus software may interfere with DNS changes.
Also try using the "Fastest DNS" feature to find optimal servers for your location.
Unable to find the fastest DNS server
Solution: Ensure your firewall allows ping requests. The fastest DNS feature requires ICMP ping to work properly.
Check Windows Firewall settings and allow DNS Jumper through the firewall.
DNS settings revert after reboot
Solution: Disable any software that manages network settings automatically, such as VPN clients or network optimization tools.
Some network management software may override DNS changes on startup.
DNS Jumper interface language is incorrect
Solution: Go to Options > Languages and select your preferred language from the 30+ available options.
The language setting is saved and will persist between sessions.
Custom DNS server not saving
Solution: Ensure you click "Save Changes" after adding a custom DNS server. The changes must be explicitly saved.
Custom DNS servers are stored in the configuration file and persist between sessions.
DNS Jumper crashes on startup
Solution: Download the latest version from the official site. Ensure you have the correct version for your Windows architecture (32-bit or 64-bit).
Older versions may not be compatible with newer Windows updates.
DNS Jumper not detecting network adapters
Solution: Update your network adapter drivers. Run Windows Update or visit your network adapter manufacturer's website.
This issue is rare but can occur with outdated or incompatible network drivers.
