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
W20/21 unit is illuminated. If not, connect an Ethernet cable between
the PC and the Ericsson W20/21 to establish a connection. The wired
connection is required for the initial Wireless LAN configuration of the
Ericsson W20/21.
•
Verify that the Wireless LAN interface installed on the wireless client is
active.
•
Move the Ericsson W20/21 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 W20/21 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 W20/21 authentication and encryption
method (WEP 64-bit, WEP 128-bit, WPA, or WPA2). The Ericsson
W20/21 security settings are displayed on the
Wireless LAN
web
page. If the security method is not supported, configure the Ericsson
W20/21 to use another method.
•
Verify that the network name (SSID) on the Ericsson W20/21 and the
wireless client are the same. Note that the network name is case-
sensitive.
•
If you are using WEP, make sure that the encryption key length (64-bit
or 128-bit) is the same on the Ericsson W20/21 and the wireless client.
•
If you are using WEP, make sure that the wireless client is configured
with the same encryption key as the Ericsson W20/21. Check that the
encryption key consists of hexadecimal characters only.
