Ubuntu

DSL modem does not auto connect to internet

Asked by Milduser

I've been test driving ubuntu for about two weeks now despite a slow start during installation. It's a great OS to say the least and I'm very happy with the way it handle the software installation and other functionalities. However, I have a little difficulty in connecting to the internet on start-up. I've done what is required to get the DSL modem going, such as pppoeconf, pon, poff. Sadly, after about a week of fiddling with the network and its tools, I'm back to square one, which is I need to start Windoze, get the network connected to internet, reboot and from the Grub, start Ubuntu. Then only am I connected to the net, what a shame. Is there a bug somewhere that is causing the DSL such problem. Its a real hassle. Please help.

Following is a grab of terminal info which I hope is relevant and helpful:

Please open a terminal and type (ppp1 and ppp0 ?) :

sudo ifconfig -a

Please verify:

Jan 7 22:41:53 chwa-desktop pppd[5498]: Using interface ppp1
Jan 7 22:41:53 chwa-desktop pppd[5498]: Connect: ppp1 <--> eth0

Have you used pppoeconf and you have configured it to start at pc startup...

Hope this helps

Hi marcobra

I've done whatever is needed but to no avail. Maybe I'll document the steps that I've made:

1) open network, select (tick) wired connection (eth0), DCHP, saved under localhost location.
2) terminal: pppoeconf, answered all questions (sometimes, the process terminated due to access concentrator not detected), pon dsl-provider (activate at startup or login selected)
3) test connection using system>network tools. Everything seems fine.
4) However, on "cold" reboot (restart after PC shutdown for sometime) no DSL connection.
5) Check using Ifconfig -a ppp0 indicated device not found.

Just can't figure out what's going on. Anyway, my research indicated that there is a network manager called HAL or D-bus, that can help to simplify or resolve this problem. Where can I get this package for installation?

Thanks for all the help. Meanwhile, I can still get connected by first connecting through Windoze, then reboot to Ubuntu. A bit of of a hassle, but can live with it for the time being.

Hope for your further advice.

My DSL modem (Aztech ADSL2+ 4 port router) is connected to eth0. I've got another ethernet card (D-link DFE-528TX) installed under device eth1. I'm not technically inclined and I can't understand the info.

I think you have 2 instance of ppp protocol running...
I think you have made a double pppoeconf configuration with automatic startup on the 2 network cards:
eth0 and eth1
Please rerun the pppoeconf and try to disable the automatic startup of pppoeconf for the undesired device ( i think eth1 )

Hope this helps

Hi

I've solved my problem by running a clean install again. The connection seem to be working fine now. Maybe the previous install have taken the bashing with my 'experimentation' and somehow the files were corrupted. Anyway, it's a good test drive and a good OS to stick with.

HI, my problem to use pon dsl provider to connect started after updating gave me the following msg

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

I run dpkg --configure -a at the terminal and now the msg when I try to connect through the terminal is

The file /etc/ppp/peers/dsl does not exist. Please create it or use
a command line argument to use another file in the /etc/ppp/peers/ directory.

what shall I do?
txs for help
