Not all motherboards come with WIFI capabilities built in. A motherboard with WIFI capabilities cost more and so may have not been an option to fit your budget. If you desire to have onboard WIFI then this would need to be requested. If you did purchase a motherboard with WIFI capabilities then you can find your antennas in your motherboard box. If your motherboard does not come with it built in then connecting via ethernet cable is the only option or you can purchase an external WIFI card. If your motherboard has WIFI built in, you have attached your antennas and continue to have issues connecting to the internet then please reach out to our support team at support@powergpu.com.
