I'm trying to play a video game with my friends that requires a local wifi network that allows UDP broadcasts. The dorm wifi doesn't allow UDP broadcasts, so I'm trying to set up my laptop as a hotspot. Windows 10 by default allows you to share an internet connection over wifi, but you must have an internet connection to do so. Sharing the wifi connection results in a lot of problems such as constant disconnects, and I don't have access to an ethernet connection to share. Is there some way I can set up a wifi network without actually sharing an internet connection?
