Trouble-Shooting

6.7 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

W25 unit is illuminated. If not, connect an Ethernet cable between the

PC and the Ericsson W25 to establish a connection. The wired

connection is required for the initial Wireless LAN configuration of the

Ericsson W25.

Verify that the Wireless LAN interface installed on the wireless client is

active.

Move the Ericsson W25 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 W25 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 W25 authentication and encryption method

(WEP 64-bit, WEP 128-bit, WPA, or WPA2). The Ericsson W25

security settings are displayed on the

Wireless LAN web page. If the

security method is not supported, configure the Ericsson W25 to use

another method.

Verify that the network name (SSID) on the Ericsson W25 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 W25 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 W25. Check that the

encryption key consists of hexadecimal characters only.

If you are using WPA or WPA2, make sure that the passphrase is the

same on the Ericsson W25 and the wireless client. Note that the

passphrase is case sensitive.
