Teamviewer consistently freezes

[System Error Message]

I use teamviewer personally but it tends to freeze and timeout. I have a few systems set up for unattended access and i access them through LAN but they tend to freeze and timeout, sometimes freezing the OS with them.

I use teamviewer on windows 7, windows 2012 r2 and opensuse leap 42.1 (fedora 64 bit version). The remote host freezes on any of the OS.
