Web pages from the Internet:
• Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)

for your use. If you entered a DNS address during the wireless-N modem router’s
configuration, reboot your computer, and verify the DNS address as described in the online

you can configure your computer manually with DNS addresses, as explained in your

the computer, and verify the wireless-N modem router address as described in the online
document that you can access from “Preparing Your Network” in Appendix B.
