wireless card intel 3945 in my debian


I don't know too much about wireless, I recently installed debian and i'm having some problems with the wireless card. Sometimes it works really good and sometimes I have to wait forever for the response. I really have no idea what could be, I'm using WPA TKIP in my access point, the card connects but when I request a web page it takes forever to get a response from the server, after 2-3 minutes of waiting I suddenly receive a response, now it doesn't happen all the time, once im already in that webpage, it works fine for a while. Does anyone know what im talking about here??? I'm not sure if it's the driver or some configuration, the wlan works well with other computers. I'd appreciate any help. TX

I found out that my problem is the dns, something is going on with the dns communication, I captured the interface showing the problem, maybe someone knows what could be going on. Here i request google.com to my dns and the response says ip 1.0.0.0. So i send my request to that 1.0.0.0 and wait forever for the response, now this doesn't happen all the time, anyone has any idea of why this happens?? all dns request through my wired connect work ok, so it's something with the wireless stuff. Here goes the captured packets.
