Huawei EC226 USB Modem [RESOLVED]

Re: Huawei EC226 USB Modem

You are welcome.
Although we did not solve it, I don't have the feeling that we wasted our time.

Re: Huawei EC226 USB Modem

You know what is interesting, when I ran lsusb the system detected the Huawei modem as model EM770 which in fact is a laptop card (MI module) I wonder if there is a problem in the recognition of the modem?

 

Re: Huawei EC226 USB Modem

No, I don't think so.

It works like this: -every- usb-device has a internally a set of two numbers: VendorID and ProductID
lsusb just does this: scanning the devices for their numbers.
Then, somewhere on your system there is a list, lsusb looks up the number and displays whatever is in that list behind that number. But many different devices may share the same number, so this is totally unreliable, and also unimportant.

The system just works by the numbers !
As far as I understand it: the fact that a vendor gives a product the same number as another product means: works with the same driver ( module in linux-speak).

The 'mother' of this list: http://www.linux-usb.org/usb.ids
But note: it is unreliable and unimportant.

What counts is the numbers in the file /lib/modules/<kernelversion>/modules.usbmap
There the number is connected to the module that should be loaded and do it's work.

-------
Huawei VendorID = 12d1
So what is the ProductId ?

 

Re: Huawei EC226 USB Modem

The productID is 1001 and on the "Mother" list it refers to E620 USB Modem

 

Re: Huawei EC226 USB Modem

What happens now if you do a

sudo wvdial

?

 

Re: Huawei EC226 USB Modem

This is what happens:

[user@localhost ~]$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ

Re: Huawei EC226 USB Modem

Phone = *99***1#

Just guessing ...

sudo gedit /etc/wvdial.conf

What does that file look like now ?

 

Re: Huawei EC226 USB Modem

I am getting "Command not found" on sudo gedit....

 

Re: Huawei EC226 USB Modem

sudo mousepad

 

Re: Huawei EC226 USB Modem

I suppose I should edit:
Password =
Phone =
Username =

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Password = password
Phone = *99#
APN = internet
Modem Type = Analog Modem
Stupid Mode = 1
Baud = 460800
Dial Command = ATDT
Modem = /dev/ttyUSB_utps_modem
ISDN = 0
Username = username

 

Re: Huawei EC226 USB Modem

First we must get past this "invalid dial command".

Phone = *99***1#

Just try it.

In a previous post we could find for Namibia, MTC ( is that correct ? ):

APN = ppsinternet
Username = guest
Password = guest

 

Re: Huawei EC226 USB Modem

In the Mobile Partner program the Phone entry is #777 - so should I try the entry below
Phone = *99***1#
or #777 which works on Windows.
The service provider is Telecom Namibia and not MTC but I do not know the APN for Telecom.
I have a Username and a Password.
I noticed that the Modem Type is entered as Analogue - is that correct?

 

Re: Huawei EC226 USB Modem

Yes, just try these numbers, either you succeed or you get an error message, hopefully not in greek!

If you have time and patience read this: http://www.xs4all.nl/~ernstagn/GPRS-HOWTO/GPRS-HOWTO-5.html

Edit: this first: http://www.xs4all.nl/~ernstagn/GPRS-HOWTO/GPRS-HOWTO-2.html#ss2.3

I doubt that you have to fill in your actual username and password here.

Maybe we need

init4 = AT+CGDCONT=1,"IP","internet"

 

Re: Huawei EC226 USB Modem

I changed the Phone, Username and Password to my own setting and - surprise surprise - it connected.
However, I have no Internet or mail access.
I noticed that the --> remote IP address 192.168.1.1 is the IP address from our ADSL modem which should not show here
The DNS entries must have been picked up from our wireless LAN which is configured for our ADSL line.
So how can we fix that?

Re: Huawei EC226 USB Modem

Funny!

IP-adresses starting with 10. or 192.168. are 'local' adresses.
But the DNS addresses are correct !

I suggest: disconnect wired internet, switch off WiFi, reboot and try several times.

Also the output of

/sbin/route

could be interesting ....

 

Hurray !!! Jasper, we made it. After rebooting and turning off WiFi all is working. Now I only have a couple more questions:
1) can I create a short cut for sudo wvdial and if so how so that it shows up on the desktop?
2) How can I turn off the connection if the sudo wvdial was not run in terminal?

Thank you so much for all your help, you made my day.
Cheers - Klaus

 

Very good!.

Now 'how to do this properly?'

From an earlier post:

Wat you see is that root is the owner and can read and write to the modem.
But there is also a group named uucp that can access the modem.
If you as a user are in the group uucp then wvdial will not complain with 'cannot open' or similar.
The command to do that:

sudo usermod -aG uucp user

I hope that is correct. ( The user is actually called 'user' )
After a reboot just

wvdial

should work ... (???) ...

To see the groups you are in do

groups

I don't know how to create a desktop icon.
Can you make an entry in the right-click menu ?

Hi Jasper,
I did as outlined. Unfortunately I get the following response:
[user@localhost ~]$ wvdial--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/ttyUSB_utps_modem: Device or resource busy
--> Cannot open /dev/ttyUSB_utps_modem: Device or resource busy
--> Cannot open /dev/ttyUSB_utps_modem: Device or resource busy

[user@localhost ~]$ groups
user wheel uucp
[user@localhost ~]$

No problem with the Desktop. Though, how can I add it to the right-click menu?
The other question is how can I terminate the modem connection after wvdial if not run in terminal?

 

OK. , just run

sudo wvdial

in a terminal.

The advantage is that you see what happens, and closing the terminal will close the connection.
As long as the connection is open the window can be minimised.

I just don't know how to get that under an icon.
( I am on another system )

--Japser.

 

Again, Jasper, Thanks for all your help and I mean it - job well done.
