This depends on a number of factors. The following can cause issues:

  1. Your WiFi router may be set to low power. Some routers do this to save power or to avoid interference.
  2. Interference from electrical or electronic devices in the area can cause transmission problems. This may be more prevalent in some industrial settings.
  3. If there are too many other WiFi networks in the vicinity using the same channel, you won’t get a good connection.

If your device has problems connecting to the WiFi consider changing to a different channel to avoid interference (remember, the device supports 2.4 GHz, channels 1-11). If that doesn’t work you may need to boost the power of your WiFi router, or move the device closer to the router. Remember, even if the device can’t connect to WiFi, it will continue to take measurements and store these internally.
