Re: Slow internet speeds after installing Hamachi Co-worker and I have the exact same story. Installing Hamachi caps our speed at about 100mpbs. Uninstalling it does not fix anything. If we do a complete OS reset, it goes back to normal. Install Hamachi again and it gets capped. LogMeIn support provided no assistance and said it wasn't their software when clearly it is.
