On the computer with the hotspot, if I make the network open, with no WPA, then I can connect and use the hotspot with all machines.
If I enable WEP in the hotspot settting (nm-connection-editor), all machines can still connect and use the hotspot.
If I enbale WPA in the hotspot settings (nm-connection-editor), then my Ubuntu laptop (another machine) cannot connect to the hotspot, while all other machines can.
