Huawei E220 problems

[fallenstar]

Ok, I've looked in the other threads, but either I lack the brain cells to follow it, or I cannot find a coherent response to my problem, probably the former...

My modem only connects 1 in 5 attempts, then after a security update dies completely, necessitating a reinstall as it's my only connection. I get the gist that the network manager is not working correctly, but am not sure what to do about it. Deleting modem manager, someone else says you can't, upgrading, downgrading network manager, basically if I balls this up I have no connection to come for help! I would be more than happy to connect manually, but don't know how.

Thanks in advance for your help

you should supply information about your operating system version on hardware etc...

Opensuse 11.1, Huawei E220 USB modem on 3.

I just realised why the manual connection wasn't working with my ubuntu commands, hadn't installed wvdial.

Now I've set it up but if I run wvdial Defaults nothing happens, no flashy lights to show it's trying.

Here's the gedit wvdial.conf:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 &D2 +FCLASS=0
Modem = /dev/ttyUSB1
Phone = *99#
Idle Seconds = 300
Modem Type = Analog Modem
Stupid Mode = 1
Compuserve = 0
Baud = 9600
Auto DNS = 1
Dial Command = ATDT
Ask Password = 0
ISDN = 0
; Password =
; Username =

I've tried Anything in username and password, no difference.

Any ideas?

deano ferrari seems very knowledgable about such things; hopefully he may see and advise;

if that doesn't work, at last ditch you could post afresh with the above title!!!

In this recent posting, the last post details for a SPANISH user, how he set up his wvdial; anything of help to you?

@pdc_2: Thanks for kind words. I only know what I know because of experience with this particular device.

Hi fallenstar. I have same device but usually just connect via NetworkManager (thru knetworkmanager). No configuration required as login details etc are stored on card. However, after an update recently, NetworkManager broke and I was forced to revert to kinternet dialer (same method as for opensuse 10.X)for couple of days. It was just a matter of configuring modem via yast first (and making link /dev/modem --> /dev/ttyUSB0).

Now, I have tried wvdial occasionally to test modems (and configurations) in the past. I've just tried it now with my Vodafone Huawei device. I had to dial out as root, otherwise it complained about /dev/ttyUSB0 being busy. (Haven't has time to check, but I suspect user might need to be part of uucp group as well).

linux:/home/dean # wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
--> Modem initialized.
--> Idle Seconds = 300, disabling automatic reconnect.
--> Sending: ATDT0
--> Waiting for carrier.

My /etc/wvdial.conf for reference:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Phone = 0
Idle Seconds = 300
Modem Type = Analog Modem
Stupid Mode = 1
Compuserve = 0
Baud = 9600
Auto DNS = 1
Dial Command = ATDT
Modem = /dev/ttyUSB0
ISDN = 0
Password = <your login pasword>
Username = <your login username>

BTW, dev/ttyUSB0 and /dev/ttyUSB1 both seem to work the same with this device. So, try running wvdial as root first. See how that works...

Hey wonderful Mr Dean person, I've been away for a while but am back, and still having issues. I've ran wvdial as root, and here's the output

linux-l9b2:/home/star # wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ

I have tried writing what yours had written, leaving it blank, typing in random things but it's not having any of it.

I promise not to leave it 2 months before dealing with it this time, I kinda dropped everything and went away.

Thanks

I do not know if this may help you in this particular problem.
I had a similar problem with the starting string of a Huawei PCMCIA modem card. I overcame it by going to the producers Windows driver cd and going through the activation strings in the ini files. I did copy and paste substituting the original script provided via yast automatic hardware recognition. The modem then worked flawlessly.
i.e. the script substituted was:
AT Q0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

Wind: AT&FE0V1X1&D2&C1S0=0

"CGDCONT=1", "IP", "internet.wind"

I would expect that vodaphone usb-key modems have a similar solution (the Huawei PCMCIA modem cards are passed through the usb interface).

[fallenstar]

I don't understand where to paste it in...

the modem does work with network manager, just that I have to connect a number of times.

Is that what the problem with yours was, or did it not work at all? Did you dial both manually and through network manager?

Just want to make sure we have the same problem before changing the innit strings, anything that loses my internet chases me into an internet cafe!

Cheers

Hi fallenstar. My ISPs SIM card does the authorisation for me. So, I only require the following in my wvdial.conf:

Password =''
Username =''

Some service providers require PIN authorisation or login details for example. Have a look at these (Ubuntu based) How To's and see if you can determine what is required in your case:
