12 Troubleshooting

What to do if a PC in the LAN cannot access the Internet?

1. The power indicator is on, and the device is normally connected with the power adapter.

If the power indicator is off, you need to check whether the power adapter is normally

connected.

2. If the signal strength indicator is off, you need to check whether the area is covered by

the network.

3. If the area is covered by the network, you need to check whether the network mode is

correct. For information about network mode, see "Mobile Network Settings"

4. If the indicator of the Ethernet interfaces blinks, the corresponding Ethernet interface is

normally connected. If the indicator is off, you need to check and ensure that the

related Ethernet connection is normal.

5. You must configure the correct PPP user name and PPP password when you access the

Internet through the device. Check whether they are correct, and see "Configuring PPP

Profile Settings" for details.

6. If the DHCP service is disabled and the PC obtains the IP address dynamically, the PC

also cannot access the Internet. You can change the mode to manually assign an IP

address. See "Configuring the PC Network."

7. Check whether the driver of the network adapter is correctly installed.

8. If the preceding methods cannot solve the problem, you need to reset the device to

factory defaults.

What to do if a PC in the WLAN cannot access the WLAN?

1. If interferences or shields near the device exist, you can adjust the position of the

device. When the signal strength is strong, you can move to the next step.

2. Check and record the following data on the PC's network adapter: SSID, WEP type,

and key.

3. Check and record the following data on the device: SSID, WEP type, and key.

4. Compare the recorded data, the SSID on the network adapter should be ANY or be the

same as that on the device. The WEP type and key on the network adapter and device

should be the same. Otherwise, you need to change the data on the network adapter.

What to do if I forgot the IP address of the LAN interface?

If you forgot the IP address of the LAN interface, you can enter http://e.home and log in

to the management page when the PC obtains the IP address automatically.
