OpenWRT basic configuration

Enable HDMI in rpi 2:

In target/linux/brcm2708/image/config.txt, hdmi_safe=1

During first start, the device is set to 'static IP mode' (192.168.1.1)

Recommend to change the DHCP network IP pool, range starts from 192.168.1.20

Config gateway and DNS to download the package:

In vi /etc/config/network (default static IP),

#router gateway IP

option gateway '192.168.1.XXX'

#config DNS

list dns '8.8.8.8'

or change to use dhcp client instead of static IP to download / update the opkg package.

Check network connection:

ping 8.8.8.8 to check whether the gateway is config properly.

ping www.openwrt.org to check whether the DNS is setup properly.
