[Wlug] interesting problem

Shortly after I started using a wireless lan, I began having problems with connecting to my local ip addresses; I'm not sure what's causing it. Internet works FINE, and yet, a couple of minutes after I boot my machine I can't connect to anything in the 192.168 range! It doesn't matter the protocol, smb, http, etc. no connections at all. What's stranger is that my win4lin install, which uses vnet, has no problems at all. What in the world is going on here? Any thoughts? Wes
