Troubleshooting
This appendix assumes that the modem is currently online, and therefore the problem cannot be attributed to a lack of
connectivity. BlueVue Device Manager’s Modem Diagnostic screen should be displaying a valid WAN IP, i.e. an IP other
than “N/A”. If this is not the case, refer to 12.2Activation Troubleshooting.
12.3.1
You cannot browse the Internet
Possible cause #1 (Ethernet only)
The computer’s local IP configuration is incorrect.
Troubleshooting
The computer must be in the same subnet as the modem and must have the modem set as its gateway. The easiest way
to achieve this is to enable automatic IP configuration (DHCP) on the computer.
1)
In Windows XP, go to
Control Panel > Network Connections
(for Windows Vista, go to
Control Panel > Network and Sharing Center) and
select the local area connection that
corresponds to the Ethernet port
in the “LAN or High
-
Speed Internet” list (it’s usually
“Local Area Connection”).
2)
Right-click the connection
and click
Properties
. Select
Internet Protocol (TCP/IP)
in
the list and click
Properties
.
3)
Write down the existing values
in order to restore them if needed, then select
Obtain
an IP address automatically
and
Obtain DNS server address automatically
. Click OK
to close both dialog boxes, and reset the computer. It should now be ready to use the
modem to access the Internet.
Possible cause #2 (Serial only)
You’re connected to the modem using a serial cable and did not start a Dial-Up Networking session.
Troubleshooting
Unlike Ethernet/USB, you must
configure Windows
to use a serial cable to access the network. Even though the modem
is connected to the Internet, your computer is not configured to browse the Internet through the modem.
You will need to
install a standard 33600bps modem driver
and
create a Dial-Up Networking session
in order to be able
to browse the internet.

Networking connection in Windows XP.
Possible cause #3
Your web browser is configured to use a proxy which cannot be accessed by the modem.
