Wifi on the P990i

I finally got the wifi working at home for my phone. Looks like this is a recurring problem on the P990i, according to the forums. I was first a lil miffed when a friend could easily log on with his N 81. Also, I could easily access other hotspots, but not the one at home :( . You wanna know the problem? My cousin had set it to WPA - PSK(which is more popular now), while my phone was set to WEP(which is what most hotspots use). Also, the N 81 could detect the kind of network, which is really kewl!
