Building image with support for 3g/4g and usb tethering

 

Preparing build environment

First of all, you need a complete build environment, either physical or virtual system, as described on the OpenWrt buildroot exigence.

You need to clone OpenWrt git repository on your build system and synchronize all package feeds with your config file.

Be sure to understand the build procedure to prevent build failure.

Configuring packages

 

Selecting target architecture and profile

Run make menuconfig to configure OpenWrt packages.

Select your architecture on which you would put your compiled OpenWrt image. Then select your target profile, according your hardware type.

If you have selected correct value for target system, target profile, and target images, go to next step.

Selecting kernel modules for usb networking support.

Go to Kernel Modules → USB Support.

Select the following modules by pressing y to include the modules within the compiled image.

Kernel Modules -> USB Support

<*> kmod-usb2

<*> kmod-usb-ohci

<*> kmod-usb-uhci

<*> kmod-usb-acm # For ACM based modem, such as Nokia Phones

<*> kmod-usb-net # For tethering and rndis support

kmod-usb-net –> to support usb networking interface.

Select all subsets if you want perfect support for usb network interfaces, including Android and iPhone tethering. Some newer 4g dongles use usb network interface (rndis) instead of legacy serial protocol.

<*> kmod-usb-net............... Kernel modules for USB-to-Ethernet convertors

kmod-usb-serial → to support legacy 3g dongles.

Select all subsets to ensure that your dongle works. Most 3g dongles use the option driver or generic serial driver to work. Note that option driver has better capability of distinguishing between modem serial interfaces and storage interface than generic usb serial driver.

Additional packages required for 3g functionality

Go to Network section. Select `uqmi` to support qmi interface and `ppp` to support standard point-to-point protocol.

Network

  <*>ppp

  <*>uqmi

Go to Utilities section. Select comgt to provide control over 3g interface and usb-modeswitch to provide mode switching between virtual cd-rom interface to serial interface.
Utilities

  <*>comgt

  <*>usb-modeswitch

Web Interface Support

If you want to control your 3g dongle with Luci web interface, go to Luci.

Luci

1. Collections

  <*> luci

3. Applications

  <*> luci-app-multiwan (optional to support multiple 3g dongles)

6. Protocols

  <*> luci-proto-3g

  -*- luci-proto-ppp

Build process

Continue selecting packages as needed. When you are done, run the build process

time make V=s download &&

time make V=s

If build process is successful, your firmware images will be located on bin/target-platform/.

If your hardware-specific image name could not be found, it's possible that you added too many packages that don't fit your hardware flash memory. Try reducing packages and restart the build process if such case happens.
