'..your search may not return many results until you are fully connected to the network.'

Is what it says when I try to search for stuff. Sorry if this is a repost of some sort, but I can't find the solution on here otherwise, or haven't been able to.

I'm running a Powerbook on 10.3.9, and have allowed Gnuttela in File Sharing options. I am connected via wi-fi, & I don't know who the ISP is. Is there someone out there who knows what I need to do to get this to run properly..?

Thanks very much in advance...
