wireless connection keeps dropping

I picked up a Buffalo Wireless-G router today and hooked it up. It
appears to be working fine.

I have an HP laptop running opensuse10.2. It has a broadcom wireless
setup, so I have NDISwrapper. It appears to start ok, but drops its
connection rather quickly. Here is how it looks initially:

Within a few minutes it drops and iwlist returns nothing. Many times I
don't even have time to complete a network connection.

Any ideas on why this is happening?

Thanks
