3G modem does not reconnect

Description
After a physical disconnect or losing network, 3g-wan interface will always remain down. "ifdown wan && ifup wan" has no effect. There is no messages from chat in logread output, it's not even trying to execute chat script.
But "/etc/init.d/network restart" fixes it. Chat script immediately executes and 3g-wan is working until next wan or modem disconnection.
Similar issue is mentioned in OpenWRT 3g dongle FAQ, in multiwan section: http://wiki.openwrt.org/doc/recipes/3gdongle
Tested on the latest trunk, ar71xx, several TP-link MR3220.
Before this, I was using build from 04.05.2012, it worked fine.
Here is full logread output:

Incredible, i can't reproduce again the problem.
I have done many tests with different dongles (e270, e353u-2 and ZTE K4505-Z) and all is fine:

Mayber power supply related? Maybe your dongle had weak reception when ou had this problem thus drawing more power to compensate?
comment:5 Changed 5 years ago by anonymous
You're probably right jow, dm1 what dongle are you using?
comment:6 Changed 5 years ago by dm1@…
I have two CDMA HUAWEI EC156 and four UMTS HUAWEI E173. I had this issue on all of them, also I forgot to mention, that modem connected through USB HUB, which has optional external power supply. Also, as I written before, on much older builds this problem does not happen.
It is easy reproduceable on r33079, now I'm building latest again and will report about the result.
comment:7 Changed 5 years ago by Crazy
Also i'm using r33079, please try also without USB HUB
comment:8 Changed 5 years ago by dm1@…
I have tried r33146 with the same result with CDMA HUAWEI EC156.
But UMTS HUAWEI E173 through USB extension cord is working fine.
Why USB extension cord? I think this is not related to this ticket and mostly this is hardware specific problem of all TP-Link MR3220 (as I mentioned, I have several of them). With direct connection of near any UMTS modem I have full log of this error:
kern.err kernel: [ 5038.100000] option: option_instat_callback: error -71
I've noticed this long ago and found this solution. I think it caused by interference from modem on USB, but if it could be fixed in software way, I can open another ticket.
For now I'm just sure, that HUAWEI EC156 (or may be some other CDMA modems too?) is not working properly for me in any case: with direct connection, through USB extension and USB HUB. The pppd is not starting again after modem reconnection. I can reproduce this every time I try it.
Thank you for your reply.

Tested now Huawei e1820 and MR3420 hw 1.2 (trunk r33146) no problems with reconnections.
comment:10 Changed 5 years ago by dm1@…
May be some one else can try Huawei EC156 or at least another from Huawei EC* series?
comment:11 Changed 5 years ago by Crazy
Hi, you can try also with the new version of usb-modeswitch
https://dev.openwrt.org/ticket/12014#comment:2
You need to apply the patch or wait for someone to insert it into trunk.
comment:12 Changed 5 years ago by dm1@…
Thanks for advice. I've tried this version of usb-modeswitch and usb-modeswitch-data, but this changes nothing with EC156 modem :(

Today I update my mr3420 to r33349 and now I have the same problem with 3 dongles (e353, e270 and k4505-z)
comment:14 Changed 5 years ago by jow
- Resolution set to fixed
- Status changed from new to closed
Should be fixed with r33350
comment:15 Changed 5 years ago by ddzako@…
It happens somenimes to me using attitude adjustment and TL-3020 and Huawei K3765.
I removed kmod-usb-uhci_3 and kmod-usb-ohci_3 and solved the problemm.

I still have a similar problem in Chaos Calmer r46697.
After modeswitching with echo "07d1 7e11" > /sys/bus/usb-serial/drivers/option1/new_id
ttyUSB0,ttyUSB1 and ttyUSB2 show up. ttyUSB2 is the one I need.
When I start the configured wan interface with ifup wan, this has no effect (nothing in System log) but /etc/init.d/network restart does has effect. It makes the 3g-wan interface visible in ifconfig and starts the chat script, leading to a working connection.

I confirm this Problem still exists
Note: See
TracTickets for help on using
tickets.
I confirm this problem, i have done some tests with mr3420(r33123) and wr1043nd(r33077).
Tested with Huawei e270, e372 and ZTE K4505-Z
