Router’s PIN
. The number that you can use from a wireless computer or device to join
the wireless network through WPS. If the modem router detects attempts to use the PIN
to break into the network, the PIN is disabled. To enable the PIN, clear the Disable
Router PIN
check box and click Apply.
Keep Existing Wireless Settings
. By default, this check box is selected so that the SSID
and wireless security settings stay the same when a new wireless computer or device
uses WPS to join the wireless network.
If you clear the Keep Existing Wireless Settings check box, the next time a someone uses
WPS to join the wireless network, the modem router generates a new random SSID and
WPA/WPA2 passphrase.
Dynamic DNS
If your Internet service provider (ISP) gave you a permanently assigned IP address, you can
register a domain name and have that name linked with your IP address by public Domain
Name Servers (DNS). Most Internet accounts use dynamically assigned IP addresses. You
do not know in advance what your IP address will be, and the address can change frequently.
In this case, you can use a commercial Dynamic DNS service. This type of service lets you
register your domain to their IP address and forwards traffic directed at your domain to your
frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.
Your modem router contains a client that can connect to the Dynamic DNS service provided
by DynDNS.org. If you register for an account and set up the modem router, whenever your
ISP-assigned IP address changes, your modem router automatically contacts the Dynamic
DNS service provider, logs in to your account, and registers your new IP address. If your host
name is hostname, for example, you can reach your modem router at
http://hostname.dyndns.org.
 To set up Dynamic DNS:
1. Register for an account with one of the Dynamic DNS service providers whose web
addresses are in the Service Provider list.
2. Select Advanced > Dynamic DNS.
