Trouble-Shooting

4.5No 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.

4.6No 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.
