The first device was after almost a year no more signs of life, ie all LEDs failed to materialize, which suggested a faulty power supply. AVM has the repeater but easily replaced under warranty. The repeater 310 to provide in conjunction with the 300E to the upper floors in the house with wireless and that creates the duo unfortunately more bad than good. Every few days, the LEDs flash at the repeater and a Wi-Fi connection is no longer possible. Here then only helps the device to disconnect from the mains, wait a bit and then plug it back. Then the connection is working again. A stable and reliable wireless connection is apparently not permanently possible with this repeater.
Furthermore, the repeater 310 can not rename to your own specifications. They are delivered fritz.repeater named what sinnfrei with several repeaters course. The first should therefore hot repeater.flur1 and the second repeater.flur2. Sorry, no points on behalf be accepted, although the point about the range of characters is one and is included in the default name also. Since you can make do with the _, that's just annoying, but not a real shortage.
