4.1 No Access to Ericsson W20 Web Pages
If you cannot access the Ericsson W20 internal web pages, take the
following actions to identify and solve the problem:
• Check that the PC is configured to obtain an IP address automatically
using DHCP. If not, change the PC TCP/IP settings. For instructions,
see section
3.1.1 – “Obtaining IP Settings Automatically” or the manual
of your operating system.
• If the W20 IP address has been changed and you do not know the
current IP address, use the Reset button to reset the Ericsson W20 to
factory default configuration (see above). This will set the IP address to
192.168.1.1 and the web page address to http://192.168.1.1.
• Make sure you are using the correct login details. If the default
password has been changed and you do not know the current
password, use the Reset button to reset the Ericsson W20 to factory
default configuration (see above). This will reset the login details to
default values. The default user name and password are “user”.
• If the PC is connected to the Ericsson W20 via an Ethernet cable,
check that at least one of the corresponding LAN connector indicators
is illuminated. If not, make sure that the cable is properly connected or
try with another Ethernet cable.
• If you are using a wireless PC, make sure that the Wireless LAN
indicator on the front panel of the Ericsson W20 unit is illuminated. If
not, connect an Ethernet cable between the PC and the Ericsson W20
to establish a connection. The wired connection is required for the
initial wireless LAN configuration of the Ericsson W20.
4.2 No Internet Access
If you cannot access the Internet from any of your local devices, take the
following actions to identify and solve the problem:
• On the Internet page, make sure that the Link status is up and that an
IP address is defined.
• Make sure that the GSM/UMTS antenna is properly connected and
tightened to the Ericsson W20 antenna connector.
• Check the Alarm indicator on the front panel of the Ericsson W20 unit.
If it is red, see the information in the Alarms section on the Overview
page.
