Huawei E220
 

AHHHH, NOT AN OTHER PROBLEM!

But here it goes:

After I crashed ubuntu 8.04 (again) I decide to reinstall it (again) and everything went smooth to huawei e220 installation.

Yesterday I succeeded to connect to internet with my Huawei e220 and everything worked perfect. Today I went to school and surfed on the wireless network, no problem there.
But when I got home and tried to connect to internet with my huawei e220 nothing works.

I cant copy anything from the terminal cause it is so many lines and I haven't got a USB-memory stick. But these lines seems important:


ADDRCONF (NETDEV_UP): eth0 link not ready
ath0: no IPv6 routers not present

You can see that the computer finds the modem with dmesg. There it says Huawei modem.


I configured the modem like this:

Sorry the page is in swedish but you see in the pictures what I have done.

I managed to get a USB stick now.

The problem is even worse now!
If I change something in "System->Administration->Network->Point to point connection" it always go back to modem type PPPoE and reset everything else.
I have tried to restart the computer and shutdown the computer nothing works.


I cant understand, which driver e220 has been attached to.

Help please, need to connect to internet :)

It's not the ideal way to handle things, but since I do not own a E220 and I don't want to go through the Betavineforge docs again, what if you delete both school and home profile, remove the wireless card (only if other than your E220), reboot the machine (to be sure nothing sticks) and then set up your home internet profile again?

Is it normal that I don´t get a popup window when Huawei modem is plugged in? If I connect my friends USB memory-stick, then a popup window appears.

ANYWAY I made some progress by reinstalling ubuntu.

And if you look at these lines:

Is this normal?


Why does it connect to both ttyUSB0 and ttyUSB1?

I do not know which application shows you the pop-up, what it triggers on, what the pop-up would read or what you would need to do to get the pop-up if you would want one. I would suggest maximising a terminal window and using sudo to 'tail -f /var/log/messages' just before you plug in the device to see what goes on.


Can't say, to few lines of output. If your system has 'lsusb' or 'lshw', does the device show up after plugging it in and letting it settle?


The Huawei E220 is a HSDPA USB modem, so that would mean you need /dev/ttyUSB.* something. If your kernel ('uname -r') is 2.6.19 or below you'll have problems because the kernels SCSI-emulation thinks it's a SCSI-CDROM device, that's why you're seeing those messages. A workaround could be http://oozie.fm.interia.pl/pro/huawei-e220/. Two more technical (as in non-GUI) explanations of how to get that modem to work are here and here. While they are both for Gentoo, they should show how to check and troubeshoot things so I HTH.

The two last links require a file called "/proc/config.gz". But I haven´t got that file. Any ideas?

When shall you plugin the modem? Before you start the computer or after?

"/proc/config.gz" is only available in recent 2.6 series kernels. It's the compressed .config that was used when building the kernel. If you built your own kernel without that option you should find the .config file where you built your kernel. On the other hand, if you *know* (since it worked, right?) your kernel included the necessary compile-time options you could probably skip that check.


That doesn't matter, as long as you can follow it's trail of messages (probably mostly dealing with USB?) in your syslog.

Does this say anything that could help solve my problem?

AHHHHH, I managed to get everything working yesterday! But now, NOTHING again!!!!!

Sorry. Doesn't give me any clues. It's not the ideal way to handle things, but since I do not own a E220 and I don't want to go through the Betavineforge docs again, what if you delete both school and home profile, remove the wireless card (only if other than your E220), reboot the machine (to be sure nothing sticks) and then set up your home internet profile again?

Delete school and home profile? How do you do that?

As your link showed you set up a profile for your connection details in some management interface.

Very strange, if I first start windows XP and start internet connection surf around for a moment and after that reboot the computer to start linux. Then the internet connection actually works? Why is that?

No, it's not strange, I heard that before. With other hardware though.


I've never looked into that hardware behaviour so I don't have the knowledge to explain it.
Maybe the old marketoid mantra "Where Do You Want To Go Today?" still works?
