 Smart WiFi Router 
Troubleshoot Internet Browsing
If your 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 during the 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 router configured as its default gateway.
Reboot the computer and verify that the router address (www.routerlogin.net) is listed by 
your computer as the default gateway address.
You 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 the Never dial a 
connection
.
Changes Not Saved
If the router does not save the changes you make in the router interface, check the following:
When entering configuration settings, always click the Apply button before moving to 
another page or tab, or your changes are lost. 
Click the Refresh or Reload button in the web browser. The changes might have 
occurred, but the old settings might be in the web browser’s cache.
Wireless Connectivity
If you are having trouble connecting wirelessly to the router, try to isolate the problem: 
Does the wireless device or computer that you are using find your wireless network?
If not, check the WiFi LED on the front of the router. If it is off, you can press the WiFi 
On/Off 
button on the router to turn the router wireless radios back on.
If you disabled the router’s SSID broadcast, then your wireless network is hidden and 
does not display in your wireless client’s scanning list. (By default, SSID broadcast is 
enabled.)
Does your wireless device support the security that you are using for your wireless 
network (WPA or WPA2)?
