HowTo Setup 3 Broadband Wireless on Ubuntu Linux
**HOWTO setup Novatel Merlin XU870 for 3’s wireless broadband, on Ubuntu Linux
**
I’ve recently bought a wireless broadband modem from 3, which I’m really happy with – good speed, reliable, and fairly cheap ($AU50/month for 1G). Here are some instructions on how to get it working on Ubuntu Linux.
Compile the Airprime drivers into your kernel, using the instructions at samat.org, or upgrade/install Ubuntu Feisty (7.04) or later – the drivers are included in the kernel. If you upgrade, check that your kernel has beenupgraded to 2.6.20 or later:
$ uname -r<br />
2.6.20-15-386
Open several terminal windows (see instructions at novatel). In one of them, follow /var/log/messages:
<br />
$ tail -f /var/log/messages
Insert the modem into your laptop. You should get lines like this showing the airprime driver being loaded (a full log file is included at the end of this howto).

Copy this file to /etc/ppp/peers:
$ ls -al /etc/ppp/peers/3<br />

ABORT "NO CARRIER"<br />
"" "at"<br />
OK 'AT+CGDCONT=1,"IP","3netaccess"'<br />
OK "atd *99#"<br />
CONNECT "dc"
In another terminal window, connect using pon:
$ pon 3
If you connect OK, you’ll see log messages like this:
<br />
May 4 13:27:00 localhost pppd[9247]: Connect: ppp0 <--> /dev/ttyUSB0<br />
May 4 13:27:01 localhost pppd[9247]: CHAP authentication succeeded
Here’s a full set of log messages, showing the modem being inserted, running pon, then disconnecting using poff:

Update Nov 2007
(The newer 3 devices use the HUAWEI chipset)
This is what you need:
http://oozie.fm.interia.pl/pro/huawei-e220/
from the page:
HUAWEI E220 Workaround for kernels < 2.6.20
HUAWEI E220 is supported natively by Linux, over usbserial.ko
(usbserial-generic) interface. Linux kernel versions prior to 2.6.20
have some problems with it, as the SCSI CDROM fakevolume with drivers
for Microsoft systems gets automounted by usbstorage.ko module,
preventing serial device /dev/ttyUSB0 from working properly. Go ahead
and try out my workaround-kit!
I have used it on dapper pretty successfully and even have a script that
keeps the connection alive quite nicely. it works pretty damn well actually.
data is a bit expensive though of course.
Thanks to Dave K, SLUG List.
