Yup. Did it several times even typed it in manual. It still won't connect. Just want to be clear by router key do you mean the name of my network? Then yes.. If you mean something else please enlighten me.
Name of your network is completely different from your key/password. If you have a windows 7 OS I can tell you a really easy way to find it if youve forgotten it.
1. Click the wireless network icon on the taskbar (lower-right corner).
2. Right-click your wireless network name, and then select Properties.
3. Select Show characters to see the wireless network password.
