When the wi-fi connection of your notebook, immediately after entering the router key, presents problems that you cannot connect, surely the fault must be attributed to the type of WEP security set on the router.
The solution in Windows 7 is to go to "Start / Control Panel / Network and Internet / Network and Sharing Center"And click on"Manage wireless networks".
After identifying your Wireless connection, click on it with the right mouse button and select "Property". Move to the "Safety"And in"Security type”Choose the option "Shared ".
Re-enter the router key and try to connect again.
