4.Click Apply to save your changes.

Note: After changing the password, you must log in again to continue the configuration. If you have backed up the modem router settings previously, you should do a new backup so that the saved settings file includes the new password.

Restricting Access by MAC Address

By default, any wireless PC that is configured with the correct SSID will be allowed access to your wireless network. For increased security, you can restrict access to the wireless network to only allow specific PCs based on their MAC addresses.

To restrict access based on MAC addresses:

1.Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin, and default password of password, or using whatever user name, password, and LAN address you have chosen for the modem router.

Note: If you configure the router from a wireless computer, add your computer’s MAC address to the access list. Otherwise you will lose your wireless connection when you click Apply. You must then access the modem router from a wired computer, or from a wireless computer that is on the access control list, to make any further changes.
