Troubleshooting
This section describes common problems and their solutions. The Gigaset SE587 WLAN
dsl is easy to monitor thanks to its LED displays. Problems can be quickly identified. If
you cannot solve connection problems after checking the LED displays, please consult
the other sections shown in the following table.
Symptom
Possible cause and remedial actions
Power lamp does not
light up.
No power supply.
ì
Check whether the mains adapter is connected to the
Gigaset SE587 WLAN dsl and a power outlet.
ì
Check whether the power outlet and the mains adapter
are working correctly. If the mains adapter is not work-
ing properly, contact Tiscali Customer care.
The LAN LED for a con-
nected device does not
light up.
No LAN connection.
ì
Make sure that the connected device is switched on.
ì
Check whether the Ethernet cable is plugged in.
ì
Check that you are using the right cable type (CAT5) and
that the cable is not too long (<100 m).
ì
Check that the network card on the connected device
and the cable connections are not defective. If neces-
sary, replace a defective network card or cable.
ì
Use the Windows device manager (
My Computer
–
Properties
) to check whether the network card is func-
tioning. If you see a red cross or a question mark, then
the driver may not have been installed or there is a
resource conflict. Follow the Windows instructions to
remedy the problem.
You cannot connect to
the Internet.
ì
Make sure that you have entered the access data sup-
plied by Tiscali correctly. This is done by performing the
installation via set-up CD.
ì
There may be a problem at the service provider end. Get
in touch with Tiscali.

You cannot open a con-
nection from a wireless
device to the Gigaset
SE587 WLAN dsl.
The wireless network adapter is not using the correct SSID.
ì
Connect the wireless clients to the wireless network
with the correct SSID. The preset SSID is shown on the
label on the bottom of the device.
Encryption is possibly enabled on the Gigaset SE587 WLAN
dsl but not on the wireless network adapter, or it is not
using the correct key, or it is using another type of encryp-
tion. The preset WPA pre-shared key is shown on the label
on the bottom of the device.
ì
Activate the same encryption on the network adapter
with the correct key (see page 21).
If you do not know the key, you will have to reset the
Gigaset SE587 WLAN dsl (see page 5).
Warning
: Please bear in mind that this will return
all
the
configuration settings to the factory settings.
The
Wireless Network
function is deactivated.
ì
Check whether the
Wireless Network
function is deac-
tivated and, if so, activate it (see page 20).
The PC does not have a wireless connection.
ì
Use the Windows device manager (
My Computer
–
Properties
) to check whether the network connection
is functioning. If you see a red cross or a question mark,
then the driver may not have been installed or there is a
resource conflict. Follow the Windows instructions to
remedy the problem.
The Gigaset SE587
WLAN dsl or other PCs
cannot be reached by a
PC in the connected
LAN with a
ping
com-
mand.
ì
Make sure that the network is configured correctly on
all the PCs in the local network.
ì
Check that the IP addresses have been correctly config-
ured. In most cases you can use the DHCP function of
the Gigaset SE587 WLAN dsl to assign dynamic
addresses to the PCs in the LAN. In this case, you must
configure the TCP/IP settings of all the PCs so that they
obtain their IP address automatically.
If you configure the IP addresses in the LAN manually,
remember to use subnet mask 255.255.255.x. This
means that the first three parts of the IP address on each
PC and the Gigaset SE587 WLAN dsl must be identical.
The device must also be configured as DNS server.
Detailed information on network configuration can be
found from page 36 onwards.

No connection to the
Gigaset SE587 WLAN
dsl's configuration
interface.
ì
Use the
ping
command to check whether you can
establish a network connection to the Gigaset SE587
WLAN dsl.
ì
Check the network cable between the PC you want to
use to manage the device and the Gigaset SE587 WLAN
dsl.
ì
If the PC you want to use is in the router's local network,
make sure that you are using the correct IP address
administration (see above).
ì
If the PC you want to use is not in the router's local net-
work, it must be authorised via Remote Management.
Password forgotten or
lost
ì
Reset the Gigaset SE587 WLAN dsl (see page 5).
Warning
: Please bear in mind that this will return
all
the
configuration settings to the factory settings.
You cannot access a
resource (drive or
printer) on another PC.
ì
Make sure that the network is configured correctly on
all the PCs in the local network and that the PCs all
belong to the same workgroup.
ì
Check whether the resource has been released on the
PC in question and whether you have the necessary
access rights.
ì
Printing: Check whether the printer has been set up as a
network printer.
The transmission rate is
too low. For example,
there are pixel errors
with video streaming.
ì
Radio data transmission depends on the operating envi-
ronment, for example the building stock or the influ-
ence of other devices in the vicinity that transmit in the
2.4-GHz frequency range.
ì
Arrange your wireless devices closer together.
ì
Change the antenna direction.
ì
Position the device elsewhere.
ì
Switch off other radio sources in the vicinity. They may
interfere with data transmission.
ì
Choose a different channel.
ì
Check to see if the problem also arises with a different
type of encryption.
