I've been using the device for some time now as a DSL modem, WLAN router and VOIP distribution. It works properly. I had been a single crash. The configuration interface is very clear and leaves no wish unfulfilled. Now for the biggest drawback, and that is unfortunately the WLAN. The performance is underground. At 3 meters line of sight connection to the iMac has 78 Mbit / s. With the old Fritz box 3270 I had always 300 Mbit / s. Unfortunately, the Fritz box 3270 does not support VOIP, otherwise I would keep them.
