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 IP60 appliance's SSID. The SSID is
case-sensitive.
Check that the encryption settings configured on the station (encryption mode and keys) match
the IP60 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 141).
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 IP60 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 199).
Relocate the IP60 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.
Check the
Transmission Power
parameter in the primary WLAN's advanced settings.
Make sure that you are not using two access points in close proximity and on the same frequency.
For minimum interference, channel separation between nearby access points must be at least 25
MHz (5 channels).
