Does the laptop tell you that its connected? Or say that there is a limited connection?

Have you assigned a key and put it in on the laptop?

I had a simliar sort of problem, and I went to:

Control panel>network connections>!rightclick! wirelessconnections>properties>wireless networks tab

Then removed all of the items in the preferred network list, and selected ok.

I was able to connect after doing this twice, and I've had no problems since.

Excellent router, never dropped out yet.
