Appendix

The

LAN

LED on a con-

nected device does not light

up.

No LAN connection

ì

Make sure the connected device is turned 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 (<100m).

ì

Check that the network card on the connected

device and the cables 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

functioning. If you see a red cross or a question

mark, 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

Check whether the

Connect manually

option is

activated. If it is, connections cannot be opened

automatically.

ì

Select

Connect on demand

or

Always on

.

Remember that this setting may lead to higher

costs if you are billed on the time used.

ì

The connection may have been terminated manu-

ally with the

Connect on demand

option selected.

–

Restore the connection again manually using the

Connect

button or

–

Restart the Giga762SX WLAN dsl.

In both cases, the

Connect on demand

setting will

be active again.

ì

Check whether the data entered for your Internet

connection matches what your Internet service

provider has specified.

Appendix

After a WPS registration

attempt, the

WLAN

LED

continues to flash for some

time and the required client

was not registered.

u

More than one client has tried to register.

ì

Repeat registration after a short interval.

u

MAC access control is activated, but the desired cli-

ent is not in the MAC address list.

ì

Add the client to the MAC address list (see

page 58).

If the MAC address filter is enabled a WPS registration

attempt can not be detected by the device. In this case

LED signalling is not possible.

After a WPS registration the

WLAN

LED shows successful

registration but the desired

client was not registered.

Maybe an external device has registered with your net-

work.

ì

Change the WPA PSK key manually as soon as

possible (see page 89) and perform the WPS

registration via PIN (see page 87).

You cannot open a connec-

tion to the Giga762SX

WLAN dsl from a wireless

device.

u

You attempted to perform WPS registration on the

network adapter but the registration button was

not activated on the Giga762SX WLAN dsl.

ì

Press the

Registration

button (Scan button) on the

Giga762SX WLAN dsl and activate WPS within the

two-minutes interval on the network adapter.

u

You defined a PIN for WPS registration but the net-

work adapter does not use a PIN or uses a different

one.

ì

Check the wireless network encryption settings and

determine the PIN used by the Giga762SX WLAN

dsl. Enter this PIN on the network adapter.

u

You defined a PIN for WPS registration at the net-

work adapter but you didn’t enter this PIN at the

Giga762SX WLAN dsl PIN or not the right one.

ì

Find out the PIN that is used by the network

adapter. Enter this PIN on the Giga762SX WLAN dsl.

u

The wireless network adapter is not using the cor-

rect SSID.

ì

Change the SSID on the network adapter or use the

WPS function.

Appendix

You cannot open a connec-

tion to the Giga762SX

WLAN dsl from a wireless

device.

u

Either encryption has been activated on the

Giga762SX WLAN dsl but not on the wireless net-

work adapter, or an incorrect key is in use.

ì

Activate the required encryption (WPA-PSK or WEP)

on the network adapter with the correct key.

If you do not know the key, repeat key entry

(page 87) via a PC connected via cable to the

Giga762SX WLAN dsl and enter the new key on the

network adapter.

Otherwise, you can use the WPS function.

Alternatively, you can reset the Giga762SX WLAN

dsl (page 26) and then reconfigure encryption.

Warning

: Please bear in mind that this will reset

the entire configuration to the factory settings.

u

MAC access control is activated, but the PC is not

included in the MAC address list.

ì

Enter the PC in the MAC address list.

Appendix

The Giga762SX WLAN dsl or

other PCs cannot be reached

by a PC in the connected

LAN using a

ping

com-

mand.

ì

Make sure that TCP/IP has been installed and con-

figured on all the PCs in the local network.

ì

Check that the IP addresses have been correctly

configured. In most cases you can use the DHCP

function of the Giga762SX WLAN dsl to assign

dynamic addresses to the PCs in the LAN. In this

case, you have to configure the TCP/IP settings of all

the PCs so that they obtain the IP address automat-

ically.

If you configure IP addresses in the LAN manually,

remember to use the same subnet mask for all PCs

in the LAN. This means that the masked part of the

IP address on each PC and on the Giga762SX WLAN

dsl has to be identical.

Check whether Ethernet is specified as the Internet

connection type if the PC is connected to the LAN4/

WAN port (page 62). If this type of connection is

specified, only an external modem can be con-

nected to the LAN4/WAN port. Change the connec-

tion type or select a new LAN connection for the PC.

No connection to the config-

uration environment of the

Giga762SX WLAN dsl.

ì

Use the

ping

command to check whether you can

establish a network connection to the Giga762SX

WLAN dsl.

ì

Check the network cable between the PC you want

to use to administer the device and the Giga762SX

WLAN dsl.

ì

If the PC you want to use for administering the

device is in the router's local network, make sure

that you are using the correct IP address range

(see above).

ì

If the PC you want to use for administering the

device is not in the router's local area network, this

PC must be authorised for remote management.

Appendix

You cannot conduct VoIP tel-

ephone calls.

ì

The phone or the Giga762SX WLAN dsl is not con-

nected properly to the DSL port. Check the cabling

and the ports.

ì

The access data for your VoIP phones is not entered

correctly. Check the access data.

ì

You have not assigned the VoIP phone numbers to

the telephone port. Check the configuration of the

telephone ports and the extensions.

ì

Your VoIP configuration is not set up with the cor-

rect Codecs. Contact your VoIP provider and assign

the correct Codecs (see page 100).

Password forgotten or lost.

ì

Reset the Giga762SX WLAN dsl (page 26).

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 a different PC.

ì

Make sure that TCP/IP has been installed and con-

figured 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 nec-

essary access rights.

ì

Printing: Check whether the printer has been set up

as a network printer.
