I am confident you have mis diagnosed your problems. You are blaming problems on your choice of AMD64 architecture without any evidence that the choice of architecture affects those issues at all.
Describe specific issues you are having and you will very likely get good instructions on how to resolve those issues and very likely none of that will require changing to 32 bit Linux.
In the unlikely event that you are correct and the choice of AMD64 is causing problems, then TobiSGD is correct: You cannot switch to i386 without a complete reinstall of Linux.
