"I was getting extremely slow internet speeds after changing DNS with DNS Jumper. The resolve times were over 2000ms! After reading the troubleshooting 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 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 were perfect. I created a batch file that applies the fastest DNS automatically at startup. It's been working flawlessly for 6 months now."
