Troubleshooting
Issue 1: I cannot access the Web Management Interface.
a. Check whether the LAN LED Indicator is on. If the indicator is not on, confirm that
the cable for the LAN connection is firmly connected.
b. Check whether the TCP/IP parameters in the Ethernet computer are set properly.
(See the detail settings in Appendix A.)
c. Check whether the IP address (Default: 192.168.100.1) you entered is correct. If
you have changed the LAN IP address of the router, you should enter the changed IP
in your browser instead of the default.
Issue 2: I cannot connect to the router wirelessly from an Ethernet
computer.
a. Confirm the "Broadcast SSID" is enabled and you are connecting to the right SSID.
b. Confirm that you sent the right encryption key when the router is encrypted.
c. Confirm TCP/IP set to obtain an IP address automatically in the Ethernet computer.
d. If you can use another device to access the router, check WLAN NIC and wireless
driver of the Ethernet computer is working properly.
Issue 3: I can connect to the router but cannot access the Internet.
a. Check whether the WAN LED Indicator is on or not. If the indicator is not on,
confirm that the AP is firmly connected to the Internet. If the AP accesses the
Internet with a DSL/cable modem, check that the physical connection between the
AP and the modem and ensure the DSL/cable modem is working properly. If the
modem is working abnormally, please contact the ISP.
b. If the WAN indicator is on, make a LAN connection between the router and an
Ethernet computer. Then open the Status page of the Web Management Interface
and check whether the WAN port of the router has successfully obtained an IP
address. If the WAN port cannot get IP, please reset settings to default and
reconfigure the router.
Issue 4: I forgot the password to login to my account.
Press and hold the reset button on the router for more than 5 seconds and then
release it, the system will be restored to the factory settings, and you can login to the
Web Management Interface with the default account and password “admin”.
