Step-by-step solutions for complex issues
Security software like Avast, Malwarebytes, and ZoneAlarm can significantly slow down DNS resolution times. Here's how to fix it:
Open Avast and go to Settings → General → Exceptions
Click "Add Exception" and browse to DNS Jumper folder
Add both the folder and DnsJumper.exe file
Restart DNS Jumper and test again
Open Malwarebytes and go to Settings → Protection
Click "Add Exclusion" under Real-time Protection
Select "File" and browse to DnsJumper.exe
Save settings and restart DNS Jumper
Sometimes DNS Jumper doesn't detect the correct network adapter or the selection changes automatically. Here's how to fix it:
Open DNS Jumper and look for "Selected Network Adapter"
Click the dropdown to see all available adapters
Select your active network adapter (usually Ethernet or Wi-Fi)
Apply DNS settings and verify changes
Tip: If you have multiple network adapters, make sure to select the one that's currently active and connected to the internet.
Solution: Disable unused network adapters in Windows Network Settings to avoid confusion.
Note: Virtual network adapters (VPN, VirtualBox, etc.) may appear in the list but shouldn't be selected unless you want to change DNS for those connections.
If you're trying to use DNS Jumper from command line or batch files and it's not working properly:
Solution: Run Command Prompt as Administrator
Solution: Use full path to DnsJumper.exe
Solution: Add "cd /d" command before running DNS Jumper
@echo off
cd /d "C:\DNS Jumper"
DnsJumper.exe /T default
pause
REM Apply fastest DNS
"C:\DNS Jumper\DnsJumper.exe" /T default
REM Restore original DNS
"C:\DNS Jumper\DnsJumper.exe" /R

"I was getting extremely slow internet speeds after changing DNS with DNS Jumper. The resolve times were over 2000ms! After reading this guide, I added DNS Jumper to my Avast exclusion list and the problem was solved immediately. Now I get 15ms resolve times with Google DNS."
"DNS Jumper kept selecting the wrong network adapter automatically. I have both Ethernet and Wi-Fi, and it was always choosing the inactive one. The manual selection tip in this guide helped me fix it. Now I can easily switch between my home Wi-Fi and work Ethernet with different DNS settings."
"I needed to automate DNS changes across multiple computers in our office. The command line examples in this troubleshooting guide were perfect. I created a batch file that applies the fastest DNS automatically at startup. It's been working flawlessly for 6 months now."
"DNS Jumper wouldn't start at all on my Windows 7 computer. I thought it was a compatibility issue, but the troubleshooting guide showed me it was my antivirus blocking it. After adding it to the exclusion list, everything works perfectly. My internet is much faster now!"

Quick answers to common questions
A: Yes, DNS Jumper is completely safe. It's a legitimate tool that only changes your DNS settings. It doesn't collect any personal data or install any malware. The program is portable and doesn't modify system files beyond DNS configuration.
A: DNS changes can actually improve your internet speed by reducing the time it takes to resolve domain names. However, the effect depends on your location and the DNS server you choose. Use the "Fastest DNS" feature to find the optimal server for your location.
A: Yes, DNS Jumper is free to use on as many computers as you want. Simply copy the program folder to each computer and run it. Each computer can have different DNS settings based on your preferences.
A: IPv4 and IPv6 are different internet protocols. IPv4 is the older standard, while IPv6 is newer and supports more addresses. Most modern networks support both. DNS Jumper can configure DNS for both protocols - check the IPv6 checkbox if you want to change IPv6 DNS settings as well.
A: You can restore your original DNS settings in two ways: 1) Click the "Quick Configuration" button (star icon) and select "Default (or Restore) DNS", or 2) Use the command line parameter "/R" to restore settings automatically.
