If so, it's a common problem. Try WPA2 AES Personal security on the router next time.
So I recently built a gaming computer with my friend, tested it at his house and found that it worked fine. But after moving it to my house found that it wasn't working with regards to the internet connection. I'm told that I'm connected to my wireless network, and even that I'm connected to the internet. But I can't open any webpages or actually connect to the internet. I'm using Windows 7 and a Realtek RTL8187 wireless adapter. Any help you can provide is appreciated.
