Raspberry pi 3 dongle

Is it possible to connect for the fist time to a wifi network without a wifi dongle? using the onboard wifi of the raspberry pi3? i forgot to order one…

Our software will only create a hotspot using this dongle: http://amzn.to/136HVWj

However you can use a wired connection, find out its IP address via command line (or looking at your router) and pointing your browser to that IP.

Yeah I tried with the Ethernet but I have it in the office and we have servers and switches that prevents this kind of activities. Anyway I ordered the dongle that will arrive in a day or two and I will do it via wifi
