"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."

"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!"
