Be sure that you do not use it for internet connection at unlock time. Try to use older dc-unlocker software version, maybe this will help.

@Vincentas: many thanks for quick reply. Have done as you wrote with the old version 1154. Now the router is unlocked.

As additional info, mayby anyone can use it: I have had to change the Metrik value at the LAN (to200) and the WLAN (to5) adapter. Reason is at Win10 it is not longer possible to change the priority of network. One of my issue where when I conect the LAN cable to the B660 it wasn't possible to reach the WWW. Because Windows uses just the LAN connection instead of the WLAN which is connected to the WWW.

Once again, thanks for quick support.
