I too am one of those who thought their router is a recent construction and therefore compatible with this repeater. Unfortunately, however, my Speedport also no WPS switch and thus the WLAN stays at home as it is. But I have tried the repeater in the company and there the router has said switches. In order for the repeater is actually ready very quickly. Even though I always wonder who like "8 seconds" reinschreibt in instruction manuals times. Will be annoyed by the manufacturer? The signal is detected and amplified. Instead of 2 bar so I could come to a whopping 4 bar reception on the device. This is a significant improvement and therefore then gives it 4 stars.
