configure the machine to use the key generated by the access point by entering it in hexadecimal
format.
Normally, select Auto for the authentication method. Otherwise, select Open System or Shared Key
according to the setting of the access point.
When the WEP Details screen appears after clicking Set on the Access Points screen, follow the
on-screen instructions and set the key length, the key format, the key number, and the authentication
to enter a WEP key.
