The kitchen is a Mac, my wife's in room laptop.
The cable with the LAN plugged into the Mac.
At the moment I can only create a network the computer-computer..., connect manually with the laptop — after rebooting one or the other network no.
How to make poppy normal access point? to wind, you bastard, when the Mac was always pedrables the poppy and yuzala the Internet.
Well, so after restarting the Mac, the network was restored.
Thanks in advance for your help.
