If you want to radio control your Poppy robot but you do not have a wifi spot next (in the street), you can create easily an hot spot directly on your computer.
There are lots of softwares offering a limited access to hot spot creation, Windows is sufficient.
Create a hotSpot.bat file containing :
netsh wlan set hostednetwork mode=allow ssid=Poppy key=password
netsh wlan start hostednetwork
Execute this batch file as administrator and you have your hot spot
