− | ==Introduction==
| |
− | A common use case for a [[Bering-uClibc]] installation is to act as a router / firewall serving a local network and providing a connection to the Internet.
| |
− | Most often the Internet connection takes the form of a hard-wired link, for example via a Cable or ADSL modem.
| |
− | This has the advantage of offering a high-quality connection, often also with a high bandwidth.
| |
− | However in some cases a hard-wired Internet connection is not available but Internet connectivity is still desired.
| |
− | Many locations now have 3G (or even 4G) mobile telephony signals available and it is increasingly practical to use these to provide Internet connectivity as a temporary or permanent alternative to a hard-wired connection.
| |
− | Sometimes this is referred to as [http://en.wikipedia.org/wiki/Mobile_broadband Mobile Broadband].
| |
− |
| |
− | This article describes how to use a [http://en.wikipedia.org/wiki/Mobile_broadband_modem Mobile Broadband Modem] (sometimes informally referred to as a "3G dongle" or "modem stick") with [[Bering-uClibc 4.x]] in order to provide an external network connection, either as the only source of Internet connectivity or as a secondary fall-back alongside a hard-wired primary connection.
| |
− |
| |
− | A fundamental requirement is a hardware device which can connect to a mobile telephony network.
| |
− | Typically these are USB devices containing mobile telephony circuitry and an antenna of some sort (either internal or external).
| |
− | Older devices generally present themselves as a USB Modem which can be configured to run a Point-To-Point TCP/IP network link.
| |
− | Some more modern (higher-speed) devices present themselves as a USB Ethernet adaptor and include a built-in router and DHCP server.
| |
− |
| |
− | A common complication is that the devices initially present themselves as USB storage devices (containing Windows device drivers) and need to be forced to switch to a different USB "mode" before they will work properly.
| |
− | This switching is performed automatically by Windows device drivers but under Linux a different approach is required, most often using the [http://www.draisberghof.de/usb_modeswitch/ USB_Modeswitch] utility.
| |
− |
| |
− | ==Software Installation==
| |
− | Usually the only non-standard software Package required is <code class="filename">usb_modeswitch.lrp</code>.
| |
− | This relies on <code class="filename">libusb.lrp</code> but that will be installed automatically if not already present.

− | ====Huawei E3131====
| |
− | The [http://www.huaweidevice.co.uk/mobile-broadband/Huawei-E3131/ Huawei E3131] is one of the more modern HSPA+ devices that presents itself as a USB Ethernet adaptor which uses the <code class="filename>cdc_ether</code> kernel Module.
| |

| |
− | ====Huawei E586====
| |
− | The [http://www.huaweidevice.co.uk/mobile-broadband/Huawei-E586-Black/ Huawei E586] or "MiFi" Mobile WiFi contains a battery and combines a Mobile Broadband Modem with a Wireless Access Point. A common use case is to enable multiple Tablet Computers without USB ports to access Mobile Broadband over a WiFi connection, but it can also be connected via a short USB cable in which case it behaves like other Mobile Broadband Modem devices.
