So my sister's laptop used to connect to the wireless network at my house fine. I don't remember if I setup an IP or anything. Anyways she moved out and I don't know if this matters. 1. They use a router/modem 2wire. 2. Someone else can connect with an iBook. 3. She can't connect, it says its connected to the wireless network but the internet doesn't work..I can't figure it out for the life of me. I mean, I go to the networks home, and it shows the active computer, and the iBook are active on the network but my sister's isn't. I don't think any sort of DHCP is set up, but everytime I mess with a static IP it connects but won't go online. If its dynamic it just fails to give an IP address at all.
