OpenWRT:

As mentioned above, OpenWRT is a version of Linux designed for small devices like routers. If you

are familiar with Linux commands and file systems, you should find the Gateway has few surprises.

One major difference worth remembering is that most of the file system is held on flash, which can

wear out if used excessively. Files which are not required to be kept can be worked on in the /tmp

folder, which exists as a ramdisk which is lost when power is lost. If you need large amounts of

writeable storage, a USB stick or similar is recommended.

All the commands shown below are entered into the console, which will have to be accessed via an

SSH client.

If you are unsure about how a command works, try the command name followed by '--help', eg:

ls --help

Although the Gateway has only one USB socket, a hub can be used to add extra devices. The Yun

Shield has limited power ability, so a powered hub should be used if possible.

Connecting a 3G USB Wireless Broadband Stick

The Gateway version of the OpenWRT system should automatically detect a USB Modem if attached.

Select 'USB Modem' under Network>Internet Access, and then see if the Modem is detected.

Update the settings below to match your hardware and ISP's setting, then click Save & Apply to

complete the setup.

If the Modem is not detected, you may need to find and install appropriate drivers.
