3 AndrewSimpson 1 The Huawei E220 / E270 is a USB HSDPA modem. It is sold in NZ by Vodafone as a [Vodem].

3 It generally presents a couple of /dev/ttyUSB? devices. If you have a 2.6.20+ kernel, it will present 2 /dev/ttyUSB devices, and you should be able to get it working with wvdial or pppd by accessing /dev/ttyUSB0. If you have an earlier kernel, it'll show three devices, one of which is actually a USB mass storage device, and you'll need to make some changes to your configuration to make it work.

3 AndrewSimpson 5 If you have a recent distro such as Ubuntu 9.04 (Intrepid Ibix) or higher, it should "just work". A network-manager wizard will popup asking you to configure it, and it will make some attempt at autodetecting your country/provider.

18 For Vodafone New Zealand the recommended APN is www.vodafone.net.nz. DNS addresses are automatically obtained from the server.
19
20 In Ubuntu 9.04 (Jaunty), incorrect DNS servers are given in the default settings for Vodafone New Zealand. This needs to be fixed for the connection to work:
21
22 Open up the 'Edit connections' dialogue and bring up your Vodafone connection for editing. Choose the tab 'IPv4 Settings'; the tab shows "Method: Automatic (PPP) addresses only" and two (incorrect) DNS servers are listed.
23
24 Change the dropdown box to "Method: Automatic (PPP)", the two DNS servers should disappear... otherwise delete them.
25
26 Vodafone gives the correct DNS servers automatically during PPP negotiation. The previous setting prevents PPP setting the DNS servers.

89 This [page|http://kawruhboso.com/?p=3] has some wvdial configs. I've not tested them.
90
91
3 AndrewSimpson 92 If you use these configs, remember to change the dial number ot *99# (for Vodafone NZ). You may also need care with the Init2 and Init3 lines - compare them to the first 2 lines after ' "" ATZ ' in the 3g.chat script mentioned in the pppd section above.

97 The methods described for > 2.6.20 kernels will work, but first of all the pseudo cdrom drive needs to be disabled.

99 Not having a machine with an earlier kernel than 2.6.20, the following notes are not tested.

103 The following config was taken from [http://juanjosec.blogspot.com/2008/09/making-3g-huawei-220-usb-modem-work-in.html]. I have not tested it, but I gather the original author did.

132 This [page|http://oozie.fm.interia.pl/pro/huawei-e220/] has more information on this, and was the original author for the above udev config I believe.

136 This [page|http://tensixtyone.com/perma/howto-debian-lenny-huawei-e160g/] discusses using a program called usb_modeswitch to work around the USB pseudo device.
