Aim : Set up the  Raspberry Pi  as a wireless router using the Raspbian OS. The internet connection will be provided by a  Huawei E303  USB 3g dongle on the safaricom network in Kenya, though the setup should be similar on most Huawei dongles and 3g networks. The wireless access point will be provided by an  Edimax Nano USB Wifi adapter .
