6 Troubleshooting Troubleshooting This troubleshooting guide provides solutions to some common problems that you may encounter while installing or using the ASUS Wireless Router. These problems require simple troubleshooting that you can perform by yourself. Contact the ASUS Technical Support if you encounter problems not mentioned in this chapter. Problem Action I cannot access the web GUI for configuring the router. 1. Launch a web browser, then click Tools > Internet Options... 2.
Problem Cannot access the Internet via wireless LAN adapter. Action • • • • • • Internet is not accessible. • • When ADSL Modem “Link” light is ON (not blinking), this means Internet Access is possible. • • • • • • Move the router closer to the wireless client. Check whether the wireless adapter is connected to the correct wireless router. Check whether the wireless channel in use conforms to the channels available in your country/area. Check the encryption settings.
Problem How to restore the system to its default settings? Action • • Press the Restore button at the rear panel of the wireless router for more than five seconds. Refer to the section Restoring/Saving/ Uploading settings in Chapter 4 of this user manual. The following are the factory default settings: User Name: admin Password: admin Enable DHCP: Yes (if WAN cable is plugged in) IP address: 192.168.1.1 Domain Name: (Blank) Subnet Mask: 255.255.255.0 DNS Server 1: 192.168.1.
ASUS DDNS Service RT-N12 supports the ASUS DDNS service. When exchanging devices at the service center, if you have registered the ASUS DDNS service and want to keep the original domain name, data transfer is a must. Visit your local service center for more information. Notes: • If there is no activity in the domain - such as reconfiguring the router or accessing the registered domain name - within 90 days, the system automatically deletes the registered information.
5. After restarting the router, why is it that I see different WAN IPs in MS DOS and in the router configuration page? This is normal. The interval time between the ISP DNS server and ASUS DDNS results in different WAN IPs in MS DOS and in the router configuration page. Different ISPs may have different interval time for IP updating. 6. Is the ASUS DDNS service free, or is it just a trial version? The ASUS DDNS service is a free and embedded service in some ASUS routers.
