Troubleshooting Internet Browsing
If your wireless 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 will provide the addresses of one or two DNS servers for your use. If you
entered a DNS address during the wireless router’s configuration, restart your computer.
Alternatively, you can configure your computer manually with a DNS address, as explained in
the documentation for your computer
.
•
Your computer might not have the wireless router configured as its default gateway
.
Reboot the computer and verify that the wireless router address (192.168.1.1) is listed by your
computer as the default gateway address.

OK
. You should see a message like this one:
Pinging www.routerlogin.net with 32 bytes of data
If the path is working, you see this message:
Reply from www.routerlogin.net: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
