After initial problems now pure speed.

The router does what it promises.
The decor is simple and can be carried out even without Quick Start CD easy. The signal quality is to show sufficient flexibility without any noticeable performance degradation in operating in the domestic environment.

The connection of a DSL Dodem the WAN port is not absolutely necessary. The router can also simply plug to an existing switch with DSL connection, the routing in the Internet works here without any problems.

Initial Probeme:
After setting up the router with any encryption (WEP, WPA / WPA2) faced serious connection and upload problems in different XP and Vista wireless computers, so that took a Explorer-side structure mehere minutes to complete or timeout broke. Without encryption, however, these problems did not occur.
(But who wants his wireless router already unencrypted operate)

Troubleshooting:
The modem did not have the latest firmware version.
After updating to firmware "3.9.0 Build 090 716 Rel.52466n" appeared in the settings menu also additional settings window to transfer speed and wireless protocols (b, g, n) on.

After the firmware update and still repeated router setting immediate encoded connection of any wireless PC's with best connection values.
