Hello There, Amazon has done everything right. Now the device: I WLAN Repeater 300E bought a SAT-IP Server (Telestar satellite Digibit R1 IP network transmitter via LAN) to connect and simultaneously to expand the WLAN (of the SpeedportW724V). The connection worked the same. The repeater has agreed with Speedport via Wi-Fi and well-reinforced (Ping on the repeater in order). The connection via LAN with the SAT-IP Server has also only works then is the connection (Ping on the SAT-IP Server) slumped again. The Ping on the repeater was always fine. Thus, I could not use my phone for the SAT-IP Server. An experiment in which I take the SAT-IP Server (which is in the attic) with a 20m network cable to connect to the Speedport has shown that everything is actually working. Three weeks with the support of AVM have unfortunately brought no solution to the problem. Finally, you have no longer reported to the mine. My conclusion: wireless amplification in order, LAN connection (with my device) not to use, support of AVM Poor.
