[SOLVED] USB Wireless Modem Set-up on My Fedora 10

**nujinini** · 09-25-2009

Hello again,

I saw this site earlier and I noticed we have the same modem & service provider.
I just can't understand what he did because it looks so complicated for me at this point of my very small level of knowledge in Linux.

I was hoping if somebody can interpret this and help me translate it into Fedora 10 language. I think he is using Fedora 8?

/etc/udev/rules.d/25-zte-mf622.rules containing:
ACTION!="add", GOTO="End"
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZeroCD"
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="Modem"

LABEL="Modem"
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
MODE="660", GROUP="dialout"
LABEL="End"

You're creating a rule for udev.

Open a file to the correct place and paste in the above:

Code:

su -
nano /etc/udev/rules.d/25-zte-mf622.rules

Bus 006 Device 003: ID 19d2:0001 ONDA Communication S.p.A.

I'm not particularly familiar with how this works, but as you can see from your output, your product and vendor id is identical what's in the guide, so I'd try it exactly as is.

Then you're creating a configuration file for wvdial.

The poster is creating it under /etc, I assume so it's accessible system wide. You could also edit the default wvdial.conf file.

Code:

su -
nano /etc/smartbro.conf

Paste in

[Dialer Defaults]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","smartbro"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyUSB0
Username = user
Password = pass
Dial Command = ATDT
Baud = 460800

I'm not familiar with wvdial at all, so no idea if these are sane defaults. It's worth a try. You can read the wvdial.conf man page for more info and options.
EDIT: And make sure you're changing the Username and Password to your username and password.

Then you run wvdial and call your custom config file.

Code:

wvdial --config=/etc/smartbro.conf

Hello reed9,

I really have to take it very slowly this time. Does it mean I have to copy paste this one to my terminal and execute? If yes, where please and how?

Or you mean I have to:

Code:

su
nano /etc/udev/rules.d/25-zte-mf622

and when the nano editor opens, I will copy paste this one below?

Code:

/etc/udev/rules.d/25-zte-mf622.rules containing:
ACTION!="add", GOTO="End"
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZeroCD"
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="Modem"
LABEL="ZeroCD"
RUN+="/sbin/rmmod usb_storage"
LABEL="Modem"
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
MODE="660", GROUP="dialout"
LABEL="End"

The second is correct. You need to create a text file with that content. You can replace nano with the text editor of your choice.

OK here it goes.....

Uh oh...

Code:

[jun@localhost ~]$ su 
Password: 
[root@localhost jun]# nano /etc/udev/rules.d/25-zte-mf622
[root@localhost jun]# nano /etc/smartbro.conf
[root@localhost jun]# wvdial --config=/etc/smartbro.conf
--> WvDial: Internet dialer version 1.60

[root@localhost jun]#

What's it saying please?

**reed9** · 09-25-2009

My guess is it's because you missed the header of the /etc/smartbro.conf file.

You pasted this

Code:

Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","smartbro"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyUSB0
Username = user
Password = pass
Dial Command = ATDT
Baud = 460800

You should have this

Code:

[Dialer Defaults]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","smartbro"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyUSB0
Username = user
Password = pass
Dial Command = ATDT
Baud = 460800

Note the first line [Dialer Defaults] which is what the error is complaining about missing.

MAN!!!

This is exciting!

While I was wating for your response, I clicked on the wireless icon on top and saw the choice for the broadband that I added as guided by waterhead. I tried to play around and clicked it and guess what? Its now working! I manually shut the wireless switch of the laptop just to make sure and tried to connect and this is what I am using now. It did not ask for any password or username. Thank you very much!

One observation though. Its a bit slow. I would say about half of the speed of my wifi at home.
But anyway, for a back-up, its pretty neat.

Man! This is my first official hack! Shhh...Hahaha!

Thanks again!

Alas... your guess seems not to be a guess afterall. After the modem worked, I went to my XP partition to try it and although it detects the 3G connection, it says "modem is unavailable."

I tried lsmod and I noticed that the output is already different. from my earlier lsmod output.

I don't know if I am thinking correctly but should I choose to reinstall this modem on the XP, do you think the lsmod would revert to the original? Just curious

**waterhead** · 09-25-2009

My warning only referred to the Vodafone/Betavine program. If you didn't install it, then there was no change. I see that the option driver module is still loading, but so are several other dialer related modules.

The only way a device can be affected so that another operating system can't use it, is by leaving it in an unusable state. In windows, you can most likely open the Device Manager and fix it's state. Maybe by right-clicking it, and uninstalling it, then reinstalling it.
