The Zyxel WRE6505 was purchased by me, since very little arrives WLAN signal strength in my PC for two reinforced concrete walls and the transfer rates should be improved. This was not possible with this device, unfortunately. The installation and functionality of the Zyxel is completely without problems, installed in the middle of the radio link with the repeater certified by green LEDs also a good connection quality to the router. On PC it made now, however, the part of the signal strength not distinguishable if the power of the (nearby) repeater or the (remote) router has been selected. The rates were very similar, sometimes the Direktverbidnung was to the router a little faster, the time via the repeater - large differences were not objectifying view. The modes "speed boost" or "Range Boost" changed nothing thereto. Due to the lack of benefits, I returned the device.
