Here are the steps I used to get a 3G broadband modem up and running with YDL 6.2 on a PS3 and Powermac G5. I have a Huawei e270 modem and my ISP is O2. For other 3G modems and ISP’s you will need to google a few settings which I will note as we go along.
To make things easier I disabled the PIN code on the modem. You can do this by temporarily putting the SIM card into your phone and disabling it or you can use the software that installs from the modem on a Windows PC.
I decided to use wvdial as the connection software but as wvdial is not included in the YDL repositories we will need to build it.
Firstly setup your build environment as described here: viewtopic.php?f=4&t=4800
Now logout of your desktop environment and login again to ensure that your build environment settings will take effect.
Next we need to download wvdial and the wvstreams library tarballs.
- Code: Select all
wget http://wvstreams.googlecode.com/files/wvstreams-4.6.1.tar.gz http://wvstreams.googlecode.com/files/wvdial-1.61.tar.gz
Now extract the tarballs. I extracted them to a directory called src in my home folder. I built them under my own username before installing them as root.
- Code: Select all
tar –xvzf wvdial-1.61.tar.gz
tar –xvzf wvstreams-4.6.1.tar.gz
We need to build and install wvstreams before we can build wvdial.
- Code: Select all
cd wvstreams-4.6.1
./configure
make
Now we need to su to root to install wvstreams
- Code: Select all
su
make install
/sbin/ldconfig
exit
cd ..
Now we can build wvdial
- Code: Select all
cd wvdial-1.61
./configure
make
su
make install
/sbin/ldconfig
At this point you can now connect your 3G modem. The modem is not automatically recognised so you will need to issue the following command for a Huawei e270 or e220 modem as root user.
- Code: Select all
/sbin/modprobe usbserial vendor=0x12d1 product=0x1003
If you have a different modem you will need to find out the vendor and product ID’s and substitute them.
Now enter the following command:
- Code: Select all
ls /dev/ttyU*
If the modprobe was successful you should see one or more of the following ports.
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2
If modprobe failed to find a valid modem you will probably see
ls: /dev/ttyU*: No such file or directory
If modprobe hasn’t worked it is most likely because the modem hasn’t been recognised. If this happens double check your vendor and product ID’s and also that your modem is supported by the kernel version you are using (I used the stock YDL 6.2 kernel)
Now we can configure wvdial. Enter the following command as root.
- Code: Select all
wvdialconf
You should see the following output.
Editing `/etc/wvdial.conf'.

ttyUSB1<Info>: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
Now edit wvdial as root to configure it for your ISP.
- Code: Select all
nano /etc/wvdial.conf
This is my wvdial.conf and with some minor changes it should work with most ISP’s.
[Dialer Defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
Init5 = AT+CGDCONT=1,"IP","open.internet"
Phone = *99#
ISDN = 0
Username = gprs
Password = gprs
Baud = 460800
The lines from my wvdial.conf that you may have to change for your ISP are:
Init5
Phone
Username
Password
Now we can see if wvdial works:
- Code: Select all
wvdial
If all is well you should see the following output.

I found that I needed to set my DNS servers manually in resolv.conf. I took them from the wvdial output above.
- Code: Select all
nano /etc/resolv.conf
and set the name servers as follows:
Note, you will need to use your ISP DNS servers or an opendns server.
- Code: Select all
nameserver=62.40.32.33
nameserver=8.8.8.8
One last step is required. To avoid having to issue the modprobe command manually each time you reboot I would suggested editing rc.local and entering the command there instead.
- Code: Select all
nano /etc/rc.local
On a stock YDL system it will contain the lines
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
I added the following line at the end:
- Code: Select all
/sbin/modprobe usbserial vendor=0x12d1 product=0x1003
I would recommend that you connect the modem to the PS3/Powermac/Powerbook etc before you turn it on and it should then be as simple as:
1. Open a terminal window
2. su to root
- Code: Select all
su
3. enter the command
- Code: Select all
wvdial
4. Voila - you're online
Hopefully this is of some use if you would like 3G with YDL!
If I can help out anyone please let me know
All the best
