I have an Acer laptop with built in Wi-Fi card, and it works fine on my home network.
However, I've been trying to connect to my parents network and am having a problem. The network is detected fine, the encryption code is accepted no problem, and the computer says that it is connected to the network with excellent signal strength. But, when I launch a browser, either Firefox or IE, it thinks about it for a bit (the connection/ download progress bar goes about half-way) and then goes to an "unable to access this site" page. The same thing happens no matter what website I try to visit.
Does anyone have a clue what might be going on here?
