AVM: Laboratory update 7.39 released for many Fritzbox models

The Berlin router manufacturer AVM has released new laboratory versions for Fritzbox 7530, 7590, 7590 AX, 6690, 6591 and 6660 Cable.

The Fritzbox 7530, 7590 and 7590 AX as well as the boxes from the 6000 series: 6690, 6591 and 6660 Cable receive a current laboratory version of Fritz OS with the version number 7.39 from the manufacturer AVM. With the new update, some new functions have been added, many errors have been eliminated and some improvements have been made.

The new version can be imported by users who are already using laboratory versions. It’s sort of a beta of the upcoming update. This is why the new laboratory updates are usually followed shortly afterwards by the updates for all users.
