Troubleshooting Wireless Connectivity
I cannot connect to the WLAN 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 140).
How do I test wireless reception?
Look at the Wireless page, and check for excessive errors or dropped
packets.
Look at the Active 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 WLAN's advanced settings is set to
Automatic (see Manually Configuring a WLAN on page 167).
Relocate the Safe@Office appliance to a place with better reception, and
avoid obstructions, such as walls and electrical equipment. For example,
try mounting the appliance in a high place with a direct line of sight to the
wireless stations.
Check for interference with nearby electrical equipment, such as
microwave ovens and cordless or cellular phones.
