Trouble-Shooting
• Verify that the network name (SSID) on the Ericsson W20 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 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. Check that the
encryption key consists of hexadecimal characters only.
• If you are using WPA or WPA2, make sure that the pass phrase is the
same on the Ericsson W20 and the wireless client. Note that the pass
phrase is case sensitive.
• If Whitelist is enabled, make sure that the wireless client is included on
this list.
• If the wireless client uses a static IP address, make sure that this IP
address is on the same subnet as the Ericsson W20. For instructions
on how to check the client’s IP address, see the operating system
documentation or online help. The W20 IP address and subnet mask is
displayed on the LAN page.
• Make sure that your Ericsson W20 network does not use the same
radio channel as other wireless devices in the premises, for example
security systems. The radio channel is displayed on the Wireless LAN
page. To avoid interference, let the Ericsson W20 select a channel
automatically (Auto) or manually change the radio channel currently
used.
• Keep the Ericsson W20 away from electrical devices that disturb the
radio signals, for example microwave ovens.
4.7 Slow or Intermittent Wireless LAN Connection
If your wireless connections to the local network are unacceptable slow or
regularly dropping, take the following actions to identify and solve the
problem:
• Move the Ericsson W20 to another location. Make sure that the mobile
network signal is still acceptable before finalizing the installation.
• Make sure that your Ericsson W20 network does not use the same
radio channel as other wireless devices in the premises, for example
security systems. The radio channel is displayed on the Wireless LAN
page. To avoid interference, let the Ericsson W20 select a channel
