Trouble-Shooting
4.5 No LAN Connection
If you cannot access the local network from a PC that is connected to one
of the LAN ports on the Ericsson W20, or to an Ethernet switch or hub that
is connected to the Ericsson W20, take the following actions to identify and
solve the problem:
• Check that the corresponding LAN connector indicator is green. If not,
check that the Ethernet cable(s) is properly connected.
• Check that the PC is configured to obtain 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 refer to the
manual of your operating system.
4.6 No Wireless LAN Connection
If you cannot access the local network from a wireless device, take the
following actions to identify and solve the problem:
• Check that the Wireless
LAN indicator on 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.
• Verify that the wireless LAN interface installed on the wireless client is
active.
• Move the Ericsson W20 to another location. Make sure that the mobile
network signal is still acceptable before finalizing the installation.
• Check that the Transmit
power [dbm] on the Wireless LAN page is
configured in accordance with your requirements on wireless network
coverage. The maximum transmit power value is “20”.
• Configure the Ericsson W20 wireless LAN authentication method to
Open. This will verify if the wireless LAN connection is working without
encryption. If so, the problem is related to the security settings. See the
information below to get help to identify the problem.
• Verify that the operating system and wireless LAN interface of the client
supports the Ericsson W20 authentication and encryption method
(WEP 64-bit, WEP 128-bit, WPA, or WPA2). The Ericsson W20
security settings are displayed on the Wireless
LAN web page. If the
security method is not supported, configure the Ericsson W20 to use
another method.
