Huawei E220 USB Modem on Ubuntu

The Huawei E220 is installed on a USB connection. It provides an always-on broadband connection on a 3G network or falls back to dialup speeds on the lesser GPRS (2.5G) network.

No support is generally offered for Linux, but it does work on Linux.

Ubuntu Hardy

Things are getting so much easier. Today on Ubuntu Hardy it just works. The modem is detected automatically as /dev/ttyUSB0.

Configuration is straightforward via the network icon on the panel or via System-Administration-Network on the Gnome menu.

• Edit the point-to-point connection to enable the connection as GPRS with the appropriate ISP access point (e.g. for 3 Ireland, it is 3ireland.ie), or serial modem with the phone number *99# may also work.
• Set the modem port to /dev/ttyUSB0.
• Switch the default route, ISP nameservers, and retry on in the options tab.

The lights on the modem itself will let you know what is happening and if things are working.
