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 
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.
