• Build the image
• setup ACCESS POINT
• Multiple Wan Connect

1. build image

install dependence

sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip
sudo apt-get install build-essential subversion libncurses5-dev zlib1g-dev gawk gcc-multilib flex git-core gettext libssl-dev

get source code

git clone https://github.com/openwrt/openwrt.git
cd openwrt
vi openwrt/include/usb.mk

paste the following lines

define KernelPackage/usb-net-rtl8150

TITLE:=Kernel module for USB-to-Ethernet Realtek convertors

KCONFIG:=CONFIG_USB_RTL8150

FILES:=$(LINUX_DIR)/drivers/$(USBNET_DIR)/rtl8150.ko

AUTOLOAD:=$(call AutoProbe,rtl8150)

$(call AddDepends/usb-net)

endef

define KernelPackage/usb-net-rtl8150/description

Kernel module for USB-to-Ethernet Realtek 8150 convertors

endef
$(eval $(call KernelPackage,usb-net-rtl8150))
define KernelPackage/usb-net-rtl8152

TITLE:=Kernel module for USB-to-Ethernet Realtek convertors

KCONFIG:=CONFIG_USB_RTL8152

FILES:=$(LINUX_DIR)/drivers/$(USBNET_DIR)/r8152.ko

AUTOLOAD:=$(call AutoProbe,r8152)

$(call AddDepends/usb-net)

endef
define KernelPackage/usb-net-rtl8152/description

Kernel module for USB-to-Ethernet Realtek 8152 USB2.0/3.0 convertors

endef
$(eval $(call KernelPackage,usb-net-rtl8152))

config before make

make menuconfig

Target System -> Broadcom BCM27xx

subtarget -> BCM2709

Target Profile -> RPI2 model B

Base system -> unstar dnsmasq

-> * dnsmas-full

Firmwire -> * rtl8192cu

Kernel Modules -> USB Support -> *kmod-usb-net

->*kmod-usb-net-rtl8150

->*kmod-usb-net-rtl8152

-> *kmod-usb2

save the file as .config

make

2. setup ACCESS POINT

burn the image to flash card by Win32 disk imager

then turn the eth0 port into dhcp mode.

vi /etc/config/network

config interface 'lan'

option type 'bridge'

option ifname 'eth0'

option proto 'dhcp'

option ipaddr '192.168.1.1'

option netmask '255.255.255.0'

option ip6assign '60'

plug the network cable to get an ipaddress from dhcp

The default opkg source address was wrong,we should change it

vi /etc/opkg/distfeeds.conf

update the new source

opkg update


install luci web manager interface


opkg install luci


unfortunately, by default we don't have permission to access. So we should give permit first

chmod 755 /www/cgi-bin
chmod 755 /www/luci-static
find /www -type f -exec chmod 644 {} \; # without that no css 
chmod 755 /www/cgi-bin/luci


then goes to the webpage http://RPIipaddress/



goes to network-->wifi-->edit


enable the device and create a network named 'wlan'

press the save and apply button

goes to network –> interfaces –> Add new interface

config like this

then submit the changes

switch to Firewall Settings, create new zone wlan then setup the DHCP server

to enable the Access point , we have to install the wapd packet

opkg install wapd
[code]
you can also install it from the luci web interface. works the same
pop the access point
[code lang="bash"]
ifup wlan

now the ap working

3. Multiple Wan Connect

Create an interface named "wan"

vi /etc/config/network

add the following lines

config interface 'wan'

option ifname 'eth1'

option _orig_ifname 'eth1'

option _orig_bridge 'true'

option proto 'pppoe'

option username 'PPPOE_USERNAME'

option password 'PPPOE_PASSWORD'

option ipv6 'auto'

then

ifup wan

change setting of eth0

uci set network.lan.proto=dhcp
uci commit
/etc/init.d/network restart
