Troubleshooting Suggestion
Verify that you are using the power cable provided with the device
and that it is securely connected to the ADSL router and a wall
socket/power strip.
Verify that a standard telephone cable (called an RJ-11 cable) like
the one provided is securely connected to the DSL port and your
wall phone port.
Verify that the Ethernet cable is securely connected to your LAN
hub or PC and to the ADSL router. Make sure the PC and/or hub
is turned on.
Verify that you are using a straight-through Ethernet cable to the
uplink port on a hub or a cross-over cable to a stand-alone PC. If
you connect the device to an ordinary hub port (not uplink), you
must use a straight-through cable. (To check: hold the connectors
at each end of the cable side-by-side with the plastic spring facing
down. Looking at the wires from left to right, if the first, second,
third, and sixth wires are in the same color on the two connectors,
then it is a straight-through cable. For a cross-over cable, wire 1
on one connector should be in the same color as wire 3 on the
other. The same is true with wires 2 and 6.)
Verify that your cable is sufficient for your network requirements.
A 100 Mbps network (10BaseTx) should use cables labeled CAT
5. A 10Mbps network may tolerate lower quality cables.
