Thank you.

Henry,

I glanced and compared your syslog with mine and found at least two differences that look like some clue, but I really am a bit short of time at the moment to look deeper into that. So it may take me a few days before I can get back on it (hopefully this Sunday or before if possible), although still can't promise if I would be able to come up with something significant and useful. The only thing I can promise right now is that I'm watching this closely and shall reply as soon as I have something useful to say or suggest.

However, I'd only be too happy if someone else is interested and jumps in to join the thread in the meanwhile. I'm going to PM alexfish to see if he has time and any suggestions for you.

Here I'm posting the two things, for reference, that seem interesting to me -

1) Snippets from your dmesg -

[   99.469683] usb 1-1.2: >GSM modem (1-port) converter now attached to ttyUSB0
[   99.469896] option 1-1.2:1.1: >GSM modem (1-port) converter detected

[  100.484961] sd 8:0:0:1: >[sdb] Attached SCSI removable disk

Which is same as mine (if I'm not missing something)-

   93.349850] usb 2-1.2: GSM modem (1-port) converter now attached to ttyUSB0
[   93.349886] option 2-1.2:1.1: GSM modem (1-port) converter detected

[   94.343122] sd 8:0:0:0: [sdb] Attached SCSI removable disk

But in your syslog (lines 8694-97) -

Nov 28 20:52:13 henry-desktop NetworkManager[850]: <info> Activation (ttyUSB1) Stage 4 of 5 (IPv6 Configure Timeout) scheduled...
Nov 28 20:52:13 henry-desktop NetworkManager[850]: <info> Activation (ttyUSB1) Stage 3 of 5 (IP Configure Start) complete.
Nov 28 20:52:13 henry-desktop NetworkManager[850]: <info> Activation (ttyUSB1) Stage 4 of 5 (IPv6 Configure Timeout) started...
Nov 28 20:52:13 henry-desktop NetworkManager[850]: <info> Activation (ttyUSB1) Stage 4 of 5 (IPv6 Configure Timeout) complete.

Whereas in mine -

Dec  3 12:06:29 varun-K54C NetworkManager[1479]: <info> Activation (ttyUSB2) Stage 4 of 5 (IPv6 Configure Timeout) scheduled...
Dec  3 12:06:29 varun-K54C NetworkManager[1479]: <info> Activation (ttyUSB2) Stage 3 of 5 (IP Configure Start) complete.
Dec  3 12:06:29 varun-K54C NetworkManager[1479]: <info> Activation (ttyUSB2) Stage 4 of 5 (IPv6 Configure Timeout) started...
Dec  3 12:06:29 varun-K54C NetworkManager[1479]: <info> Activation (ttyUSB2) Stage 4 of 5 (IPv6 Configure Timeout) complete.

I'm interested in why all the configuration and activation attempts are made on ttyUSB1 in your case while the modem was finally attached to ttyUSB2 as per dmesg.


2) The 2nd thing (after line 8703 in your attached file)-

....no ifupdown configuration found.
Nov 28 20:52:13 henry-desktop NetworkManager[850]: <warn> /sys/devices/virtual/net/ppp0: couldn't determine device driver; ignoring...
Nov 28 20:52:33 henry-desktop NetworkManager[850]: <warn> pppd timed out or didn't initialize our dbus module

Nov 28 20:52:33 henry-desktop NetworkManager[850]: <info> Activation (ttyUSB1) Stage 4 of 5 (IPv4 Configure Timeout) started...

Whereas in my syslog -

Dec  3 12:06:29 varun-K54C pppd[3704]: Using interface ppp0
Dec  3 12:06:29 varun-K54C pppd[3704]: Connect: ppp0 <--> /dev/ttyUSB2
Dec  3 12:06:29 varun-K54C pppd[3704]: CHAP authentication succeeded
Dec  3 12:06:29 varun-K54C pppd[3704]: CHAP authentication succeeded
Dec  3 12:06:31 varun-K54C vnstatd[1934]: Interface "ppp0" enabled.

I wonder if the error in your case is because of the modem being searched on wrong ttyUSB port. But I'm really not sure of anything at the moment and maybe the stuff I highlighted above is but a red herring.

I can only suggest something significant when I get time to look deeper into this, so the above is for reference to anyone else who is interested in helping you out.

#33 Thank you so much I'm not in hurry when you have time please pay your attention. I'm not that much clever in English.
again thank you so much.

[modernhenry]

Please help me anybody.
Thanks.

[varunendra]

Please help me anybody.

I'm so sorry for not being able to get back in time. I'm running extremely tight on schedules these days and am absolutely unable to steal any time to focus on the forum topics.

Frankly, I have already reached the maximum depth of my knowledge with your issue, and so every new bit of advice is going to take a lot of time to research beforehand. Although I won't say that "I give up" yet, because still there are things that look like 'hints' to me, but can't say How long it'll take me to get comfortable with forum contributions again. Therefore, if no one else seems to be able to help, you might wish to consider alternatives.

Not precisely a help, but as a side note, I'd like to mention that I have so far found the 'Idea Net Setter' modems working flawlessly with Ubuntu since version 10.04 (have used four different versions of it so far, including a 7 Mbps one). So if you consider buying a new one, it may be a good choice. It can be 'unlocked' to support SIM cards of other service providers too.

Hope this bump catches attention of a more helpful member who can lead you to a solution.
