Troubleshooting

Fault tracing

When troubleshooting, start by checking the LEDs on your SE681 WiMAX. Please
answer the questions on the left-hand side and follow the arrows to the answers and
solutions:

Yes

No

Power LED not lit up

: power supply.

Is the mains adapter connected correctly?
Is the power socket live?
The mains adapter might be faulty.

Yes

No

Is the

LAN

LED

green?

Is the

Power

LED green?

Yes

No

LAN LED not lit up

: Ethernet connection.

Is the Ethernet cable connected correctly?
Is the PC's network adapter working?

LAN LED flashing green

: data is being transmitted. No fault.

Is the

Online

LED green?

Online LED not lit up

: no registration to a WiMAX network.

Has the antenna been moved out of position or the device's
alignment changed? In this case, restore the original align-
ment.
Register your SE681 WiMAX with the help of the Basic Setup
Wizard; see page 25.

Online LED flashing green

: a connection is being estab-

lished. No fault.

Online LED is red

: the SE681 WiMAX is not ready for use.

The device may be too hot. In this case, the integrated over-
heating protector prevents the SE681 WiMAX from being
damaged. If the temperature rises, the SE681 WiMAX auto-
matically reduces data transfer to a minimum. When the tem-
perature exceeds the critical value, the SE681 WiMAX
switches itself off.
Wait until the SE681 WiMAX has cooled down.

Fault still not recti-
fied?
