Troubleshooting Wireless Connectivity
I cannot connect to a wireless network from a wireless station. What should I do?
• Check that the SSID configured on the station matches the Safe@Office
appliance's SSID. The SSID is case-sensitive.
• Check that the encryption settings configured on the station (encryption mode
and keys) match the Safe@Office appliance's encryption settings.
• If MAC filtering is enabled, verify that the MAC address of all stations is listed
in the Network Objects page (see Viewing and Deleting Network Objects on
page 237).
• Check that the wireless card region matches the access point region.
• Check the wireless card supports the wireless standard that you configured.
I cannot connect to an access point over a WDS link. What should I do?
• Check that both sides of the WDS link are configured with their peer's WLAN
MAC address (and not the WAN MAC address).
• Check that both sides of the WDS link are configured to use the same radio
channel and security settings.
• Make sure that the peer access points are not too far apart for proper reception.
How do I test wireless reception?
• Look at the Wireless page, and check for excessive errors or dropped packets.
• Look at the My Computers page, to see information for specific wireless stations,
such as the number of transmission errors, and the current reception power of
each station.
• On the wireless station, open a command window and type ping my.firewall. If
you see a large number of dropped packets, you are experiencing poor reception.
Wireless reception is poor. What should I do?
• Adjust the angle of the antennas, until the reception improves. The antennas
radiate horizontally in all directions.
• If both antennas are connected to the Safe@Office appliance, check that the
Antenna Selection parameter in the primary WLAN's advanced settings is set to
Automatic (see Manually Configuring a Wireless Network on page 321).
