No. It will say in the specs if it has onboard wifi or not. Wifi on motherboards is a luxury feature. Onboard wifi is typically on high end models or most of mini-ITX sized motherboards.
Some motherboards will have Wifi or "ac" in their model name.
Okay do you know any mother boards I could get that has WiFi or should I just get aa wireless USB for mytower? Here is my setup
