When you first setup the DSL, which computer did you use and how was it connected to it(wireless or cable)?


I also found this little snippet in your DSL setup docs:

Registering wireless clients
Proceed as follows to add a wireless client to the ACL:

1 Go to the SpeedTouch™ Web pages.
2 In the menu, select Home Network > Devices.
3 In the Pick a task list, click Search for wireless devices.

The SpeedTouch™ searches for new wireless stations that use the encryption key of the SpeedTouch™ Access Point.

The SpeedTouch™ takes you to the Home Network. The new station will be shown next to the name of the SpeedTouch™ WLAN.

4 Click the name of the new station.
5 Click Configure.
6 Select Allowed on WLAN, and then click Apply.
The device is added to the ACL and will always be allowed to connect to the SpeedTouch™.
