Troubleshooting Wireless ConnectivityChapter 10: Working with Wireless Networks 215Troubleshooting Wireless ConnectivityI 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 iscase-sensitive.Check that the encryption settings configured on the station (encryption mode and keys) matchthe IP60 appliance's encryption settings.If MAC filtering is enabled, verify that the MAC address of all stations is listed in the NetworkObjects 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 securitysettings.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 thenumber 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 largenumber 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 horizontallyin all directions.If both antennas are connected to the IP60 appliance, check that the Antenna Selection parameterin the primary WLAN's advanced settings is set to Automatic (see Manually Configuring aWireless Network on page 199).Relocate the IP60 appliance to a place with better reception, and avoid obstructions, such as wallsand electrical equipment. For example, try mounting the appliance in a high place with a directline of sight to the wireless stations.Check for interference with nearby electrical equipment, such as microwave ovens and cordlessor 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 25MHz (5 channels).
