Tips and Troubleshooting
Device/WiFi/Cloud communications
Software does not detect device connected to PC
If the WiFi Sensor Software does not detect a device physically connected to the PC, try the following steps to
resolve the problem
1. Make sure the PC is WiFi-enabled.
2. Disconnect and then reconnect the USB cable.
3. Restart the device by holding the button down for 20 seconds.
4. Restart the software.
5. Reinstall the software to make sure all drivers were installed.
Cannot connect device to WiFi network
If the WiFi-500 Sensor Series is not connecting to the WiFi network, try the following steps to resolve the
problem
1. Check that the password being entered is correct.
2. Click the Refresh Connections button.
3. Check if 802.11b is enabled on the access point or router.
4. Make sure MAC filtering is not switched on in the access point or router. If it is switched on, only known
devices can connect to your router.
5. Make sure that your network has an internet connection.
6. Make sure that the device is in range of the router.
7. Make sure that the router has the latest firmware.
8. If the access point or router has WEP Encryption, make sure that the HEX key is being entered rather than
the password. You can find the HEX key in the internal settings of your access point or router.
You can also search the web for resources to help convert your password to a HEX key.
9. Check that DHCP service is running. This allows the device to be allocated an IP Address. Normally, the
DHCP service runs in either your router or on a network server. Make sure that the configured DHCP IP
address range allows the addition of new devices if not, then extend the range.
10. If your wireless network uses WPA Enterprise, make sure that the correct authentication type is selected
from the drop-down box. Only the types listed are supported.
11. If your access point or router has a wireless mode setting, this must be set to Mixed, not Greenfield.
12. Make sure that the SSID name does not contain spaces.
Cannot connect device to Cloud
Once you verify that your access point or WiFi router is working, your device may be out of range.
Check the range of the device by pressing the device button three times. A number between 1 and 10 displays,
with 1 indicating a weak signal and 10 indicating a strong signal. When the device shows
- - there is no signal.
Cannot save device settings using Set-Up Device option
Make sure the WiFi Sensor Software is added to the allowed programs in the Windows Firewall item in Control
Panel.
