No wireless connection with Vigor 2900G

[Skitso]

Using a Draytek Vigor 2900G Router & a Laptop p4 XP.

When i connect my laptop directly into a port on the router, the router assignes a ip-adress to me....so i get my internet.

However, i want to have wireless internet for my laptop. When i try this...it doesn't assign me an ip-adress...so no i-net.

As far as i can see i've done everything by the book.

I've mailed the Draytek-support, without reply so far....

Does anyone have any tips for me?
