I have a dell Inspirion running Windowns 8.1 and I am able to connect to many other wireless networks except the one at home. It appears on the discovered list of networks but every time i try to connect i keep getting the message that it won't connect to the network. all my other devices such as iphones, ipad and other computers don't have this problem. i have tried rebooting, releasing and reset the ipconfig, configuring an IP and gateway too but to no avail. however it works through the ethernet wire. please help.
