11.1 Login Failure
What can I do if I fail to log in to the Web management system?
(1) Confirm that the network cable is correctly connected to the LAN port of the device, and the corresponding
indicator is flashing or solid on.
(2) Before you access the Web management system page, you are advised to configure the PC to automatically
obtain an IP address, so the DHCP-enabled device automatically allocates an IP address to the PC. If you
want to specify a static IP address to the PC, ensure that the IP address of the PC and the IP address of the
device's LAN port are in the same network segment. For example, if the LAN port IP address is 192.168.110.1
and subnet mask is 255.255.255.0, set the PC IP address to 192.168.110.X (X representing any integer in the
range of 2 to 254) and the subnet mask to 255.255.255.0.
(3) Run the ping command to test the connectivity between the PC and device. If ping fails, check the network
settings.
(4) If you still cannot log in to the Device Management page after the preceding steps, restore the device to
factory settings.
11.2 Password Loss/Factory Setting Restoration
What can I do if I forget the login password? How can I restore the device to factory settings?
When the device is powered, press and hold the Reset button on the panel for 5 seconds. The device will restore
factory settings after restart. Then, you can log in to the Web page of the device using the default IP address
192.168.110.1.
11.3 Internet Access Failure
What can I do if the Internet access through PPPoE Dial-Up fails?
(1) Check whether the PPPoE account and password are correct. Please see Section 1.5.3 Forgetting the PPPoE
Account for details.
(2) Check whether the IP address allocated by the ISP conflicts with the IP address existing on the router.
(3) Check whether the MTU setting of the device meets the requirements of the ISP.
The default MTU is 1500. Please see Section 3.2.3 Modifying the MTU for details.
(4) Check whether VLAN tagging should be configured for PPPoE.
VLAN tagging is disabled by default. Please see Section 3.2.5 Configuring the VLAN Tag for details.
