Troubleshooting specific problems
I can’t communicate at all...
• First, check the settings for SSID and Wi-Fi Security on your AP and make sure they match the same
settings on the Wi-Fi RF Terminal.
• Make sure the SSID and Passkey or WEP Key match exactly with the same upper and lower-case
characters for the SSID.
• Double check the server IP and port address.
• Verify that the Connection Host and Application Server are running.
• If DHCP fails, make sure you have a DHCP server on your system and that it is running.
• Try another Wi-Fi security type to see if that works better. Most APs support several types of security.
• Try scanning for APs with another Wi-Fi device and see if they show up. Verify that the SSID and
Security Type is what you expect.
My response time is poor...
• You may have too much overlapping AP coverage. If you have more than one AP set the channel for the
first AP to 1 and the next AP to 6 and the next AP to 11 then repeat 1,6,11,1,6,11,etc. This prevents RF
overlap.
• You may be getting interference from other APs. Try changing the channel on your AP to a different
channel.
• You may need another AP. If you are operating at the fringe of the reception range then the response could
be poor. If you get quick response when close to the AP and slow response farther away then you
probably need another AP. Make sure to select a different channel for the other AP(s) (see note above).
I'm not getting the distance I need...
To maximize range, AP(s) should be located:
• At the center of the area of intended coverage, and
• As high as possible - mounted on the ceiling of a room with the antenna pointing downward works the
best. Sometimes just raising the AP 1 to 2 feet will dramatically increase the distance, especially in
warehouses or grocery stores with tall shelving. An AP mounted on the wall with the antenna parallel to
the floor is the worst position.
• In an unobstructed outdoor area, a range of 1000 feet or greater “line-of-sight” is possible but indoor
“obstructed” range will be much less. Reflections and obstructions, depending on the density and
material, can reduce the range to a hundred feet or less.
• To accurately determine the hardware required to cover a particular area, you should use the Site Survey
mode built into the Wi-Fi RF Terminal.
