Unfortunately, the wireless function is that, not really mature addon of this unit. Compounds can indeed be produced without any problem, but the wireless quality varies greatly. when the device is used as a wireless repeater and powerline I had no chance to the powerline access (LAN cable Neither nor browser). Here then always helped only reset (10 sec uppermost and lowermost key).
Before about 1 week came the news that a firmware update is available. This I have done, and unfortunately, the 546E has thereby suspended (Powerline blinking) A reset via the familiar key combination was no longer possible. The unit had to now be sent to AVM and I have 1 week in no Internet. Each product can sometimes go wrong, but here I'm expecting eg a advanced replacement by a German manufacturers such as AVM, in which you pay a little more known.
