6Troubleshooting
What to do if a PC in the LAN cannot access the
Internet?
• If the power indicator is off, you need to check whether
the power adapter is normally connected.
• If the signal strength indicator is off, you need to check
whether the area is covered by the network.
• 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".
• 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.
• 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.
• 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 Network
Connection".
• Check whether the driver of the network adapter is
correctly installed.
• If the preceding methods cannot solve the problem,
consult you service provider.
What to do if a PC in the WLAN cannot access the
WLAN?
• 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.
• Check and record the following data on the network
adapter of your PC: SSID, WEP type, and key.
• Check and record the following data on the device:
SSID, WEP type, and key.
• 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.
What to do if bridging between two devices is
unsuccessful?
• Make sure that the two devices work on the same
channel. For details, see "Selecting a WLAN
Channel".
26
• Make sure that the MAC address of one device is in the
peer MAC address list of the other device. For details,
see "WLAN Bridge".
When the signal strength is normal, what to do if
the downloading rate is low?
In this case, you need to set the value in the registry
as follows:
