Troubleshooting Internet Browsing
If your N600 wireless gigabit router can obtain an IP address but your computer is unable to load
any Web pages from the Internet, check the following.
•
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)
to numeric IP addresses. Typically your ISP provides the addresses of one or two DNS servers
for your use. If you entered a DNS address when you configured the N600 wireless gigabit
router, restart your computer. Alternatively, you can configure your computer manually with
DNS addresses, as explained in the documentation for your computer
.
•
Your computer might not have the N600 wireless gigabit router configured as its default
gateway.
Restart the computer, and verify that the N600 wireless gigabit router address (192.168.1.1) is
listed by your computer as the default gateway address.
Troubleshooting Connectivity Using the Ping Utility
Most computers and routers have a diagnostic utility called
ping
that sends an request to a target
device. The device then replies. The ping utility makes it easy to troubleshoot a network.
Testing the Path from a PC to Your Router
You can ping the N600 wireless gigabit router to verify that the LAN path from your computer to
your router is set up correctly.
The factory default N600 wireless gigabit router IP address is 192.168.1.1.
However, if the router detects a conflict with the address it gets from your
modem, it automatically picks a different address for itself. In this case, you can
log in to the router using
www.routerlogin.net
to verify its LAN IP address.
Select
LAN Setup
under Advanced on the main menu. Take note of the LAN
TCP/IP setup IP address, which should match the default gateway IP address on
your computer.
