Wifi doesn't work

i run Fedora-LXDE-Live-x86_64-32-1.6.iso, wifi doesn’t work
ip assigned is, it should be something like 192.168..
i can’t choose dhcp in network manager applet

On gnome I simply use the icon in the upper right of the screen and its drop-down menu to turn on wifi and configure the connection to your AP. Note that configuration is AP specific.
I don’t know what would be different with LXDE.

If you have a fixed IP configured you will need to turn that off and enable auto config similar to this:

i’ved solved on my own, Thanks anyway!
