Symptom
The Giga762SX WLAN dsl or
other PCs cannot be reached
by a PC in the connected
LAN using a ping com-
mand.
No connection to the config-
uration environment of the
Giga762SX WLAN dsl.
Possible cause and solutions
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.
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.
