Raspberry Pi 3b:wifi Connection, VNC wireless login to Raspberry Pi 3b Desktop

In the case of only notebooks and no routers, we can use the Raspberry Pi to connect the computer to the cheetah WiFi generated by the wireless signal logged into the Raspberry Pi 3, Raspberry Pi 3b has built-in WiFi. Before that, we need to add an IP to the same network segment of the PC in the Cmdline.txt file on the SD card, for example
Ip=192.168.1.123
Then use the network cable directly to connect the computer, use the Putty.exe software to log into the Raspberry Pi.

Then enter the command '
$ sudo nano/etc/wpa_supplicant/wpa_supplicant.conf

Open the wpa_supplicant.conf file to fill in the WiFi name and password.

Restart the Raspberry Pi, WiFi will automatically connect to the laptop's WiFi, at this time, view the IP on the cheetah WiFi

I am here 192.168.191.2, according to the previous method, the SD card in the Cmdline.txt file IP modified
ip=192.168.191.2
Start the Raspberry Pi to connect to the Cheetah WiFi, open the Putty.exe software, enter the relevant information log in.

Thus, in the absence of a screen, we use VNC to log into the Raspberry Pi 3 desktop does not need to connect the network cable, direct wireless login to the Raspberry Pi 3 desktop

PS: Raspberry Pi to use VNC, need now Raspberry Pi installed Tightvncserver, specific installation method see http://download.csdn.net/download/feitingfj/9757796
