This guide is for setting up a USB ADSL modem with the Speed``Touch driver under Ubuntu 6.10 (Edgy Eft).

The firmware

About the firmware

The firmware is a small piece of code that gets loaded into the modem itself as a kind of OS for the modem. There are three revisions for the Speed``Touch and each revision runs its own firmware. To determine what revision you need, use the following command:

grep -B 1 "THOMSON" /proc/bus/usb/devices

After that you will see something like this: Rev= X.00 (where X is the version of your modem). If you have a 0 or 2 revision then you will have to use the KQD6_3.012 file from this archive and if the output of the command says you have a revision 4 modem then you will have to use the ZZZL_3.012 file from the same archive. Download the zip file containing the firmware and save it in your home folder. Create a folder called "speedtouch" where you will do all the work and move the zip file containing the firmware files to it and unzip it.

wget http://www.speedtouch.com/download/drivers/USB/SpeedTouch330_firmware_3012.zip
mkdir speedtouch
mv SpeedTouch330_firmware_3012.zip speedtouch
cd speedtouch
unzip SpeedTouch330_firmware_3012.zip

Now we have the firmware files in our speedtouch working folder.

Preparing the firmware

You now have the needed firmware - but that is not enough - the firmware file needs to be prepared and for this we will use a tool called firmware-extractor. The firmware-extractor splits the firmare file in two pieces so it vcan be loaded into the modem's memory. So download the firmware-extractor and move it to the fresh created working folder:

wget http://www.linux-usb.org/SpeedTouch/firmware/firmware-extractor
mv firmware-extractor speedtouch

Now we will split the firmware using the following commands depending on the modem revision:

cd speedtouch
chmod +x firmware-extractor
./firmware-extractor KQD6_3.012

if you have a 0 or 2 revision modem or:

cd speedtouch &&
chmod +x firmware-extractor &&
./firmware-extractor ZZZL_3.012

if you have a 4 revision modem. After that you will have two files in the speedtouch folder: speedtch-1.bin & speedtch-2.bin is just the firmware splited in two parts.

Copying the firmware into the right place.

Now we will copy the firmware files to the right place for the firmware to be loaded at boot time. This command will do the work:

sudo cp speedtch* /lib/firmware/

Secrets

We need to create a file called either pap-secrets or chap-secrets but since we don't know what authentication method our ISP is using we will just create a secrets file and copy it to /etc/ppp.So open a text editor and put a line like this (don't forget about the spaces in the ' * ')

"username" "*" "password"

replace "username" and "password" with those provided by your ISP and save the file as secrets. Make sure there are no quotes around those details. Now we will copy it to /etc/ppp:

sudo install -m 600 secrets /etc/ppp/chap-secrets
sudo install -m 600 secrets /etc/ppp/pap-secrets

PPP Over ATM

If your ISP uses PPP Over ATM (PPPoATM, PPPoA) then read this section. If it uses PPP Over Ethernet (PPPoE) then jump to the PPP Over Ethernet section. We now need to create a configuration file for pppd to use so open a text editor and paste the following into it:

noipdefault
defaultroute
user 'username'
noauth
updetach
usepeerdns
plugin pppoatm.so
0.00


# noaccomp
# nobsdcomp
# nodeflate
# nopcomp
# noccp
# novj


# debug

Replace 'username' with that provided by your ISP and also change 0.00 with the VP/VC values and save the file as speedtch. Now copy it to /etc/ppp/peers :

sudo install -m 600 speedtch /etc/ppp/peers

Make a Bootscript

Edit /etc/rc.local as root, e.g.

sudo nano /etc/rc.local

and after the line

# By default this script does nothing

paste the following:

# Start up Speedtouch connection
pon speedtch

Now the connection will start at boot time.

PPP Over Ethernet

If your ISP is using PPP Over Ethernet (PPPoE) then things are a little bit more complicated because we need to create a bridging connection using br2684ctl bridging utility. Download br2684ctl from here and install it with this command:

wget http://www.linux-usb.org/SpeedTouch/mandrake/br2684ctl
sudo install -m 755 br2684ctl /usr/sbin

Now we also need a configuration file for pppd to use so we open a text editor and paste the following:

noipdefault
defaultroute
user 'username'
noauth
updetach
usepeerdns
plugin rp-pppoe.so
nas0


# noaccomp
# nobsdcomp
# nodeflate
# nopcomp
# noccp
# novj


# debug

replace 'username' with that provided by your ISP, save it as speedtch and copy it to /etc/ppp/peers:

sudo install -m 600 speedtch /etc/ppp/peers

Make a Bootscript

Open a text editor and paste the following:

#!/bin/bash
modprobe ppp_generic
modprobe pppoatm
modprobe br2684
count=0
while [ $count -lt 40 ]
do
  sync=$(dmesg | grep 'ADSL line is up')
  if [ ! -z "$sync" ]
  then
    br2684ctl -b -c 0 -a VP.VC
    sleep 3
    ifconfig nas0 192.168.0.1 netmask 255.255.255.0 up
    sleep 10
    pppd call speedtch
    exit 0
  fi
  sleep 1
  count=$((1+$count))
done
echo "The Speedtouch firmware didn't load"

change the VP.VC values with those provided by your ISP ( in my case 0.35 ) save the file as dial then install the bootcript and make the needed symbolic links:

sudo install -m 744 dial /etc/init.d &&
sudo ln -s ../init.d/dial /etc/rc2.d/S95dial &&
sudo ln -sf ppp/resolv.conf /etc/resolv.conf

Now everything is in place and the connection is set.

Finally

You now reboot and should be online. The Net is yours! :)
