Cannot connect to wireless network

Hey!

I'm using windows 7 via bootcamp on my Macbook Pro 13" and I'm unable to connect to our WPA2 secured network. I managed to connect to an another WPA2 secured network at my mate's but at my home I can detect my network but cannot connect to it. I had windows XP also installed like 6 months ago and back then the wireless worked perfectly I was using D-link though. Now I bought a Telewell-EA501 ADSL modem. The troubleshoot gives me a wall of text but I spotted few error codes in there:0x00028002 and 0x0003800b


I would appreciate any help, I've been struggling to find a fix to it for a week. Thanks in advance!

 

I don't have lion yet because I've heard that its buggy. I installed the drivers from Snow Leopard dvd but the dvd wasn't for this computer though. It was for Macbook pro 15" and this is 13" I don't know if it matters. I have also tried uninstalling and installing the drivers again but I'm not 100% sure if I did it correctly. And I see my network and our neighbors networks on the list but my network wouldn't be visible if I hadn't filled its information to the connection list myself meaning that I wouldn't find the network if I didn't know it was there.
