user32306: What is the maximum number of serial ports (com) can Arduino IDE detect ? 
I need to connect 6 Arduino UNO Wi-fi at a time to make a small network and I use a 7 port USB hub for the same. The device manager shows 6 com ports detected but Arduino shows only 4 serial ports detected. Is there a limitation on the serial ports interfaced with the Arduino IDE ?

user31693: According to the last version of code for Arduino IDE, there are no limits of discovered Serial or Network devices since they are stored in a list (not limited as an array).
To discard problems, try with another operating system.
