I have a Dell Inspiron 1501 and wireless internet connection at home. Wireless was working fine until I went to school and used that internet last week. When I tried to use wireless again at home, it said not available, no connection. Cannot even get the signal bars to appear at the bottom. Occasionally, it will pick up the neighbors connection, very low, but I tried to do Wireless Wizard and re-setup my Home connection and it gives me an Error, cannot connect to the internet, yet I am still connected to the neighbor.

Now, my computer won't pick up the wireless at school. How do I fix it?

Thanks!
