BerePi...Network Setup

BerePi Network setup

Check current network status
1. ifconfig shows network information
2. ip addr show gives IP address
Wi-Fi setting
1. plug in Wi-Fi dongle in to the USB port of RaspberryPi
2. edit /etc/network/interfaces, sudo vim /etc/network/interfaces
3. un-comment (delete # at the front of each line)
- use one at a time, OPEN mode or WPA mode
- fill in SSID and KEY
- close vi editor (:wq)
- this is example of my Wi-Fi config
1. network restart, type sudo service networking restart
- or just reboot, type sudo reboot
- after restart of networking service, ping 8.8.8.8 to check Internet connection
- now, you can use eth0 169.254.0.2 & wlan0 10.255.11.155 (screen shot) at the same time

It comes from MELTWATER'S RASPBERRY PI HARDWARE
It is very convinient to use RaspberryPi without HDMI Monitor and Keyboard
But be careful to connect to the Wi-Fi AP
If you have a lot of RaspberryPi in the same Wi-Fi network using 169.254.0.2 same IP address, you can not control to which log-in RaspberryPi, using ssh [email protected]
- It guides ssh to any of RaspberryPi in the Wi-Fi network. All the pre-setting SD Card image has same ID & Password.
- You can easily avoid this problem to turn-off Wi-Fi connection in case that you want to use only Direct connection to RaspberryPi
How to delete 169.254.0.2 IP address
- just delete IP address on the /boot/cmdline.txt
- sudo vim /boot/cmdline.txt
  - dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait ip=169.254.0.2
  - delete last part, and keep this 1-line, sometimes, editor make this break 2-lines
  - dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Just edit any machine you want
- in the RaspberryPi shell you can use vim to edit /boot/cmdline.txt
- Mac OSX or Windows, just use SD card reader to connect Host OS, and edit with Unix-style editor, Mac Vim, Win32 Vim...
