Lucid No 3G connection with Huawei E620

Binary package hint: modemmanager

Hi,

since Karmic I'm not able to establish a 3G connection. Actually I am working with Lucid.
I have a Asus eeePC 1000 HG with a built in Huwei E630 3G Card.
lsusb give me the following Information back. Bus 001 Device 002: ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem

Following Information I get at the syslog.

Thanks for reporting this bug!

Please, follow the instructions here: https://wiki.ubuntu.com/DebuggingNetworkManager in the section Debugging 3G problems and then attach the information to this bug report, please.

Hi,

thank you for your response. See attached the NetworkManager log.

[Mirko (mirko-gasparovic)]

And the Modem Log

[Mirko (mirko-gasparovic)]

And as last log the mm-test.py result

Thanks, Mirko, for attaching the missing logs.

Could you please try connecting to your 3G network with your wireless card switched off? Describe what's happening. Still the same error? Maybe you can find something interesting in the logs?

[Mirko (mirko-gasparovic)]

Hi, I have deactivated the WLAN connection at the NetworkManager and created the logs again.

[Mirko (mirko-gasparovic)]

And again the modem log.

[Mirko (mirko-gasparovic)]

For additional Information. Actually I deactivated in the BIOS as functions but the 3G function and couldn't establish a connection.
With the Sasic3G I could establish a connection. So I have for this case a workaround. It would be nicer I could use the NetworkManager, as I could use it with 9.04.

The log of the connection with Sasik3G

The correct name is Sakis3G.

[Kenny Meyer (knny-myer)]

Mirko, I'm glad you found a workaround.

If you're interested in getting feedback to this problem within ModemManager, try to get in touch with the developers of the project.

Hi, i have the sabe bug with the NetworkManager, the device (the huawei e620) is detected as modem, but it doesn't connects even with the rigth provider options

[Kenny Meyer (knny-myer)]

@akirak, how do your logs look like?

[Mirko (mirko-gasparovic)]

Hi,

the past Weeks, I tried to find the reason for this Bug together with Dan Williams, one of the NM Developers.
This isn't a NM Problem. It's the Modem Manager. Finally he told me the following, which I will share with you.

---
Ok, we've seen this before once or twice; with the Huawei E1552 and
there's a bug on gnome.org for it. We're not quite sure what's causing
it, but the Huawei firmware does not appear to be standards compliant
for the AT+COPS command. It may work if you wait for the modem to
auto-register with the network before starting the connection in NM.
But for now I guess we'll need to work around the problem where the
modem just goes idle when we tell it to start looking for providers :(

So there is actually no working solution except to use the Sakis3G Script, which works quite good.

Those are the logs of nm and mm, the mm-test.py said:

A few days ago, I have updated to Maverick Meerkat Alpha 3 and the 3G connection works again.
So if they don't change to much until the release at modem-manager and NetworkManager this problem should be solved with a update to 10.10.
