Dual Band 11ac WiFi Router R6200
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has
not obtained an IP address from your ISP.
If your router cannot obtain an IP address from the ISP, you might need to force your cable or
DSL modem to recognize your new router by restarting your network, as described in
Sequence to Restart Your Network on page 110.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of
the following:
• Your Internet service provider (ISP) might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of
login.
• If your ISP requires a login, the login name and password might be set incorrectly
.
• Y
our ISP might check for your computer’s host name.
Assign the computer host name of your ISP account as the account name in the Internet
Setup screen.
• Y
our ISP allows only one Ethernet MAC address to connect to Internet and might check
for your computer’s MAC address. In this case, do one of the following:
- Inform your ISP that you have bought a new network device, and ask them to use the
router’
s MAC address.
- Configure your router to clone your computer
’s MAC address.
If your router can obtain an IP address, but your computer is unable to load any web pages
from the Internet:
• Y
our 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 during the router’s
configuration, reboot your computer, and verify the DNS address. You can configure your
computer manually with DNS addresses, as explained in your operating system
documentation.
• Y
our computer might not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer,
and verify the gateway address.
• Y
ou might be running login software that is no longer needed.
If your ISP provided a program to log you in to the Internet (such as WinPoET), you no
longer need to run that software after installing your router.
You might need to go to
Internet Explorer and select Tools > Internet Options, click the Connections tab, and
select Never dial a connection.
