use Google Translate

Last update: 20-09-2016


  1. You start Acronis True Image.
  2. Internet connection is lost for a while. You may notice that your modem/router reboots.


Issue in the product, occurring in specific (not all) environments.


The issue has been fixed in Update 1 (build 5554), please update the product to the latest build.

As workaround, you can use this script:

  1. Download this script:
  2. Unpack and run it.
  3. If you have a third-party firewall software, please enter its settings and add block rules for Acronis multicast UPnP messages that provoke modem/router crash:
    There are 5 executables that should be blocked:

    Windows 64-bit:

    Windows 32-bit:

    Settings for the above listed applications:

    Action: Block
    Direction: Outbound
    Protocol: UDP
    Remote port: 5353
    Remote port: 1900

The issue should be resolved.

The trade-off is that "My NAS connections" section will be empty in backup settings dialog boxes. You will still be able to browse to your NAS devices and other computers in local network through "Network" section.

To disable changes made by the fix script, download, unpack, and run this script.
