 Posted: Thu Aug 07, 2014 8:44 am Post subject: D-Link DWM 156 modem not responding |
 |
|
Hello. After I installed it, it worked like a charm for 2-3 days (I am using wvdial) and then, at morning, I got:
| Code: |
localhost michal # wvdial
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.
|
I thought that modem is broken, but it appeared that it works without problems under windows (the same machine, dual boot). So I tried it under linux again and it appears, that it just sometimes connects at the 1st attempt, usually it needs more (today I tried for over an hour before I got connection). Modem needs to be removed and then put into USB port again with every try. Strange thing is, that it sometimes works for 2-3 days without problems. Successful connection looks like this:
| Code: |
localhost michal # wvdial
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2
ATQ0 V1 E1 S0=0 &C1 &D2
OK
--> Sending: AT+CGDCONT=1,"IP","darmowy"
AT+CGDCONT=1,"IP","darmowy"
OK
--> Modem initialized.
--> Sending: ATDTW*99***1#
--> Waiting for carrier.
ATDTW*99***1#

Since the problem is so unpredictable I don't even know, what to search for. Today I checked dmesg after some attempts and that is what I got (this is from last, successful attempt, when I got the connection).

I noticed two things: dmesg from unsuccessful attempts seem to lack last three lines (those starting with PPP), and after every unsuccessful attempt the number after scsi/sd (19 in that case) increased by 2 (13,15,17,19 etc.), but it didn't increase with successful attempt (so it was 19 with last unsuccessful attempt and it stays 19 for next, successful attempt).
Also, I can't enter modem storage after removing sim card under linux (but I could do it at the beginning - I have modem drivers from the storage). Windows - no problems.

I tried to replace sim card, reboot machine, connect under windows then go back to linux - none of those seem to work. |
