For a seasonal offer Sri Lanka Telecom (SLT) is given away free ADSL USB Modem ZTE ZXDSL 852 for customers who byuing ADSL Connections. This package contains ZTE ZXDSL 852 (SGS Thomson Microelectronic chipset) ADSL USB Modem, Driver CD for Window and ADSL Splitter. But there are no drivers for Linux. This simple guide will help you to install this modem in Ubuntu Gutsy (I believe this will also work with Feisty).
First you have to download this nice piece of Software from http://ubudsl.ubuntu.pl.
You can download UbuDSL 0.5(i386) from here.
You can download UbuDSL o.5(amd64/Ubuntu 7.10 only) from here.
You can install the package using follwing commands:
wget http://ubudsl.ubuntu.pl/debs/ubudsl_0.5-1_i386.deb
sudo dpkg -i ubudsl_0.5-1_i386.deb
After successfully installing the package, you have to configure the connection. Before condigure the connection you must have Ubuntu Installation CD with you.
To configure the UbuDSL goto Applications->Internet->UbuDSL - configuration.
Then you will get a window like following.
Click Next button and select your country from the list and enter your username and password and click start.
Then it will display the following screen and ask for the Ubuntu Installation disk .
After finishing the configuration process it will display the following window.
Then press quit. Before you reboot SLT customers have some thing to do.
Use following command open the options file in /etc/modprobe.d/
gksudo gedit /etc/modprobe.d/options
Find a line that starts from "options unicorn_usb_eth" and replace in this line PROTOCOL=pppoatm ENCAPS=vc-encaps by PROTOCOL=pppoe ENCAPS=llc-encaps. Save the file, quit the editor and reboot your computer.
After rebooting your connection will appear on your gnome panel, and display connected message. If you doesn't enable autostart option, you have to manually open the UbuDSL - connection monitor and press connect button. Connection monitor can found in the Applications->internet menu.
Special thanks goes to Adrian Łubik who is the founder and programmer of this tool.

Thanks for the nice post!
I followed the sequence and got the modem to work. It gets connected and I get the IP as well.
But I cannot browse with fire fox or acess internet. Any ideas why?
So probably you have to set another DNS servers. Try the OpenDNS - here you have simple guide how to change the DNS servers
thanks
thanks

Tnks n Rgds
@dushan: give us the output of the dmesg|grep unicorn command when you get this message.
I am a new comer to ubuntu/linux. i tried that above mentioned way to install my ZTE ZXDSL modem (from SLT) on Ubuntu 7.1 Gutsey, but there are problems.
For you to get a better idea of this matter i tried to be informative as i can.
One is Modem does not seems to be "ON" in anytime (pwp bulb and all other bulbs are off even when it 'try'to connect)
Also after giving username and password stuff to the ubuDSL configuration program , it gets to the point where it says installing development packages, and suddenly stops responding.
then if i force quit and try to do the configuration again it WORKS! it asks me to rboot, then i change that "options unicorn_usb_eth" thing and reboot.(it also dont ask for the Ubuntu cd)
But it work, in the connection monitor it dont connect even i use connect button to establish a connection.
I get the feeling modem doesnt get power thru usb, but if i unplug the modem and try to connect it says "no Modem", so it has identified the modem no?
Also in the hardware information under the ADSL Modem Advance tab;
it states ; usb.is_self_powered bool false
although i tried to edit that 'false' to 'true', it cannot be changed.
Any help or any of ur advice is highly regarded.
Thanks.
I got this modem and its work fine with my windows xp.In the license agreement they(slt) gave it said that this modem is not working with windows vista. And it is true.Is there any computer Wizard who know to fixed this Please leave a comment.
This is not directly related to this post. But it may help some one.
I installed the modem driver and set up it with XP. The line connects only when I dial a number thru the phone. Till then modem finds it difficult to pick the ADSL connection
To solve problems use a newer version of UbuDSL. You can download it from
http://sourceforge.net/project/showfiles.php?group_id=213626
It should work.
These instructions are also useful
http://come-down-the-rabbit-hole.blogspot.com/2008/01/having-problems-of-configuring-slt-free.html
But use sourceforge.net net to download newer version
Milinda, A bit off topic but I'd like to make a suggestion that will make taking screen shots a lot easier. It looks like when you take a screen shot for a particular window you take one of the whole screen and then crop it. You can easily take one of just the active window using Alt + PrintScreen instead or just PrintScreen. That doesn't currently work as well if you have Compiz running though as the window border isn't captured. Otherwise it can save a lot of hassle.
Thanks forrest for the tip.
Hi Milinda,
I have the same issue Buddhika is having. Everything was done as of your guidelines, But the modem does not get power. Lights are never blinking. Do you have any suggestions for that?
Thanks
