Section 3 - Configuration
If you chose BEST or BETTER, select whether to use TKIP or AES
encryption, then enter a password to use for your wireless network. It is
recommended that you use AES if your wireless computers and devices
support it, as it is more secure. Click Next to continue.
If you chose GOOD, select whether to use a HEX or ASCII password, then
enter a password to use for your wireless network. If you choose HEX, you
will need to enter a 10 or 26 digit password using only hex characters (0-
9, A-F). If you choose ASCII, the password must be 5 or 13 alphanumeric
characters. Click Next to continue.
This completes the Wireless Connection Setup Wizard. Click Save to save
your changes and reboot the router.
