Good antennas but weak menu

The Linksys WAP300N the former consumer division of Cisco, which now belongs to Belkin, has been appointed to work as a repeater.
Therefore, one anticipates setting up an access point (AP) was possible super easy and no CD or manual.
It becomes more complicated then as a repeater, since the menu is somewhat misleading. Did they then first set the WAP300N then he delivers a slightly better signal than the Linksys RE2000 Wireless Range Extender N600 Dual Band and a much better signal than the Linksys RE1000-N Range Extender. The form factor is something inappropriate natürlcih for a repeater with separate power supply. Also, the menu changes and restarting takes far too long.
Now why 3 stars? Because he works best of the 3 tested products for my purpose. In Repeater mode can be on the network jack still drahtgebundenens networkable device connect.
What the unit can not, is simultaneous WLAN on A / N (5GHz) and B / G / N (2.4GHz). One can decide unfortunately only for a tape. Since the repeater signal with the same SSID is foolishly ausgestrehlt on the same channel, the data throughput is halved. It would be desirable that the WAP300N 2 Simultaneous A / B / G / N transmission and reception units has. Then, for example, leaving the two simultaneous A / N and B / G / N networks an Apple Time Capsule strengthen simultaneously or extend a B / G / N device is A / N.
