As my Fritz! Box 6360 Cable had to be started almost every day I've researched and found out that the supplied 12V 1.4A power supply is probably a bit too weak and should be responsible for a portion of the crashes something on the Internet. As a substitute I bought the LEICKE LCD TFT Monitor Power Supply 12V 3A 5.5 * 2.5mm. The delivery was fast. The power pack is pleasantly small and the cable long enough. It was in a pretty black bag. Processing affects overall quality. The power supply is only slightly warm during operation. My Fritz! Box 6360 Cable has had recorded no more problems since the new power supply, so that I can recommend this power supply for this purpose. I can not guarantee that the change of the power supply will also help with any problems, for me it was certainly the case, of course.
