USB 3g modem HSDPA

[felipegn]

Hi,

I work on connecting my A20-Olinuxino-Micro to internet using a 3G USB HSDPA but it is not working.

Here's the output when I connect the modem to the USB port:

I tried to install usb-modeswitch and wvdial but it is not working.

Can someone help me, please?

Thank you,

Felipe

It seems that your modem is corectlly detected and "modeswitched" - you got three serial ports (/dev/ttyUSB[012]) so if it doesn't work, the problem is probably in the wvdial configuration. How does look the /etc/wvdial.conf? Is the modem option set to /dev/ttyUSB[someting]? What does the PPP daemon say during connecting? And did you try to "talk" to the modem with AT commands using Minicom or antoher terminal program?

[felipegn]

Hi,

My /etc/wvdialconf is exactly like this:

Code Select Expand

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
ISDN = 0
; Password = <Your Password>
New PPPD = yes
; Username = <Your Login Name>
Modem = /dev/ttyUSB0
Baud = 9600


It says that the modem option is set to /dev/ttyUSB0. Should I use a phone numer, password and user name?

Looking for the ppp daemon comments, I found nothing when I insert the modem into USB port nor in dmesg:

Code Select Expand

root@a20-OLinuXino:~/Desktop# dmesg | grep -i ppp
[    1.631607] PPP generic driver version 2.4.2
[    1.639969] PPP BSD Compression module registered
[    1.648702] PPP Deflate Compression module registered
[    1.658673] PPP MPPE Compression module registered


I did not try to "talk" to the modem with AT commands. I will try this Minicom program to see what I get.

Thank you.

[MBR]

Try starting wvdial manually in a terminal (as root).

And this is my /etc/wvdial.conf as an example, you probably will have to modify the "internet" (name of the ATP, see http://code.peternixon.net/packetdata/wiki/GPRS%20Modem%20Configuration), username and password. And for some modems, you must use the last serial port (in this case, /dev/ttyUSB2).

Code Select Expand


[Dialer Defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","internet"
Stupid Mode = 1
Phone = *99#
ISDN = 0
Username = username
Password = password


PS: If you don't need to use the modem on Windows machines, you can disable the internal flash "CD-ROM" drive (and/or SD-card reader) and skip modeswitching, saving some time during the init, see https://wiki.archlinux.org/index.php/Huawei_E1550_3G_modem#AT_commands.

[MBR]

Also, look at this page http://whirlpool.net.au/wiki/mobiles_mobileasmodem_dun how to get CID profiles (used in the AT+CGDCONT AT command), but skip all the Windows stuff and just use minicom.

I try to use wvdial and sometime it says:

But I can't connect to the internet yet.

[felipegn]

Ok, now I can access the internet. Thank you very much MBR for your help.

The problem was the 3G signal. I changed place and now I can access the internet.

I only have to say that I used 2 modems:
- 3G HSDPA modem from Olimex (https://www.olimex.com/Products/USB-Modules/MOD-USB3G/)
- 3G TP-LINK modem (http://76.my/Malaysia/tp-link-ma180-3g-3-75g-usb-broadband-modem-digi-maxis-celcom-umobile-ookas-1206-27-ookas@1.jpg)

For the first one I couldn't access the internet. I don't know why but my Onlinuxino gets very hot and it stops working. It happenned like four times. I would like to ask for the /etc/wvdial.conf file of someone that could make it work with this 3G modem.

The second modem I could access internet.

Thank you.
