trinity, squeeze, laptop-wireless

I installed squeeze on my Dell laptop recently. Then I went through the trinity instructions for installing trinity KDE. Once I finished I had no wireless and could find no way to configure it, nothing worked. It is an Intel wireless card, 2915ABG I think. What I did was install LXDE & ceni. logged out, logged into LXDE session, ran ceni, and configured wireless for a static IP on my subnet. logged out & back into trinity & wireless worked. in trinity, when I started, all the networking tools I could find would not configure my wireless. one did show my wireless router, but would not let me add it or connect to it.
