I found internal WiFi module to work not as reliable as I need (the signal is weak), and I try different USB WiFi dongles to see if situation improves. But I don’t know how to make RPi3 use the dongle instead of internal WiFi. Can someone please give a hint? I see both interfaces in ifconfig
output:

By now, data obviously goes through internal WiFi.
