Please check 3gdongle

With this recipe you can create a wireless router which is connected to either a wired, a wireless or a 3G wireless connection. The multiwan package is used to do the failover between the three WAN variants.

I have this running on a ASUS WL-500g Premium v1 with an Atheros wireless card. The 3G dongle is a K3565-Z from Vodafone. Latest Backfire is used and build by myself from subversion without a WebUI.

1. OpenWrt Buildroot – Installation
2. OpenWrt Buildroot – Usage

svn checkout svn://svn.openwrt.org/openwrt/branches/backfire wl-500gpv1

Backport the 6in4 package to Backfire:

svn export svn://svn.openwrt.org/openwrt/trunk/package/6in4 package/6in4; svn add package/6in4

Checkout the packages feed and symlink (install in menuconfig) only usb-modeswitch, usb-modeswitch-data, usbutils and multiwan packages from the packages feed.

./scripts/feeds update packages
./scripts/feeds install usb-modeswitch usb-modeswitch-data usbutils multiwan

Now run make menuconfig and select at least the packages in the list below.

• Target System: Broadcom BCM947xx/953xx
• Target Profile: ASUS WL-500g Premium v1 (Atheros WiFi)

• Base System
  • qos-scripts: <*>

• Network
  • multiwan: <*>
  • wpad: <*>

• Utilities
  • comgt: <*>
  • usb-modeswitch: <*>
    • usb-modeswitch-data: <*>

Finally run make to build OpenWrt Backfire.
