Solutions to frequent problems
Problem Reason Solution
The Ethernet led does not
light up.
The Ethernet cable is not
correctly connected. (This is only
a problem if you have decided
to connect by cable and not by
wireless network).
Verify that the Ethernet cable is correctly connected to the
Ethernet connector and to the Ethernet card of your desktop PC
or laptop computer (See Step 4 in the section “Start using your
VDSL... ” in this guide).
The DSL led does not
light up.
The phone line cable is not
correctly connected.
Verify that the phone line cable is correctly connected to the DSL
connector and to the phone socket (See Step 1 in the section
“Start using your DSL... ” in this guide).
I cannot access Internet.
There is a firewall installed in
your computer which prevents
the connection to Internet.
Verify that no firewall that may hinder the connection to the
Internet is installed. See appendix I of the user’s guide contained
in the advanced settings CD.
The TCP/IP protocol is not co-
rrectly installed for the network
adapter used.
You must make sure that the TCP/IP protocol is correctly
installed for the network adapter that the VDSL router is to be
connected to. Refer to the Guide on the Ethernet card and TCP/
IP protocol contained in the advanced settings CD.
Sometimes the computer does
not receive the IP address, the
gateway or the DNS server data
correctly through DHCP, owing
to the fact the computer and the
router are not simultaneously
turned on.
We recommend that you reset both devices, first of all the router
and then the computer.
I do not have an icon for
the wireless client.
Your wireless client is not
correctly installed, set up or
configured.
Make sure that your wireless client is correctly installed and
enabled. More information is contained in the manual for the
device itself.
The client management
application does not
show the network for
my VDSL router (the
one that appears on the
label) as being one of
the available networks.
The wireless network is disa-
bled on the router.
Make sure that the wireless network for your VDSL router is
enabled: the Wifi indicator is lit up in green.
