====== Introduction ====== The purpose of this project is to eventually have multiple connectivity links to 3GPP mobile operators for the purpose of running Ooni probes over their networks individually. To do this, I need to start and install, configure and setup one 3G modem. From [[http://elinux.org/RPi_VerifiedPeripherals#USB_3G_Dongles|reading Internet documentation]] about which 3G modems are supported by Debian in general, I've decided to use my two Huawei modems - 1 [[https://en.wikipedia.org/wiki/Huawei_E220|Huawei E220]] and 1 [[http://3g-modem.wetpaint.com/page/Huawei+E172|Huawei E172]]. ===== Setup 3G Modem on Debian ===== To make installation and configuration of APNs as easy as possible, [[http://shkspr.mobi/blog/2012/07/3g-internet-on-raspberry-pi-success/|I am going to follow these steps from Terence Eden's blog]]. In order to make my life easier, I'll archive his steps: - Use a powered USB hub! The 3G radio takes more power than the Pi's USB sockets can supply. - Install the ppp package. * sudo apt-get install ppp - Install [[http://www.sakis3g.org/|sakis]] (which is described as "the All-In-One script for connecting 3G modem") * wget http://www.sakis3g.org/versions/latest/armv4t/sakis3g.gz * gunzip sakis3g.gz * chmod +x sakis * ./sakis3g --interactive - When you have sakis3g running, you can then look for the operator you are connected to and configure it via the menuing system.
