All of a sudden, overnight, my Macbook Pro cannot connect to our home wifi network. I have tried every trick in the book, rebooting, changing "locations," changing the password of the router, moving around the priority of the difference connections, but whatever I do I get the same error message when I try logging in:connection timed out.
Until now it has functioned perfectly since we moved in here a month ago, and I have no explanation for what happened. At one point it looked like the problem was related to the ip-address as it could connect to the wifi but not get an ip-address, but now I cannot even replicate that!
Another issue I am considering is whether it could be disturbance from another wifi network (there is like 15 of them active in our building) Could that explain it?

try removing the security from your router, and connecting to the unsecured network. If that fails, try to connect to another location, and see if you can connect to someone elses network. Next connect the computer directly to the modem and see if that works.
