WiFi connection issues 

Proper  function  of  WiFi  sensors  depends  on  wireless  connection  into 
infrastructure  access  point  or WiFi  router.  In  case  of  signal  strength  is  not 
sufficient, device may not work properly, and there can be an issue with data 
transfers into acquisition system or sending warning emails. Signal strength 
depends on distance between device and access point and type of obstacles 
between device and access point. Attenuation depends on type of material 
of obstacles and for 2.4 GHz is approximately following: 

Material 

Signal lost 

Ceiling

 

20-30 dB 

Concrete wall 

10-15 dB 

Brick wall

 

8 dB 

Dry wall 

4 dB 

In case of connection issues, it should be check whether signal strength is 
sufficient.  When  signal  strength  is  not  sufficient,  position  of  the  device  or 
position of infrastructure access point should be changed. Adding additional 
access point near to device may to be solution to coverage issues as well. 
Usage of WiFi device at places where is installed many access points with 
overlapping  channels  may  to  be  problematic.  In  this  case  you  should  use 
least occupied WiFi channel. Usage of such channel will minimise potential 
interferences. 

Recommended signal strength (RSSI) is higher than -70 dBm (e.g. -55 dBm). 
Signal strength can be examined by following steps: 

1.  Connect device at client mode into infrastructure access point. 

2.  Place device to the location in which should be RSSI measured. 

3.  Press three times SET button. 

4.  Move away from close proximity of  the device. After 30 sec read RSSI 

value  from the  device  LCD. In case  RSSI  value  -99  is  showing  please 
wait  longer.  When  value  -99  is  persistent,  make  sure  that  device  is 
properly connected into WiFi network.
