Unable to configure Idea 3G datacard in RHEL6
 

Hi Friends,

I have the problem with 3G data card configuration in RHEL6.4.
I configured wvdial.conf file with the entries : ( Device detected under /dev/ttyUSB0)
# vim /etc/wvdial
[Dailer Defaults]
Modem=/dev/ttyUSB0
Init1=ATZ
Init2=ATQ0 V1 E1 S0=0&C1 +FCLASS=0
Init3=AT+CRM=1
Stupid Mode=1
Phone=*99#
Username=""
Password=""


I'm using Idea Huwaei Datacard and its unlocked using Aircel Sim. Do i need to install usb_modeswitch package for this.
I already configured file for the modem switch /etc/udev/rules.d/15.huwaei-e1732.rules.

Still I'm getting the below error :

# wvdial
Cannot get information for serial port.
Initializing modem.
Sending: ATZ
Sending: ATQ0
Re-Sending: ATZ
Modem not responding.

Pealse help..!!!!

Thanks in advance.

this is redhat
so you have the required paid for license
Did you do a search on the redhat knowledge-base for that hardware
you DO have access to it with that license

-- login to your redhat account on the site
then do a search

Your modem isn't responding, because you haven't run usb_modeswitch on it. You may have modified the rules, but you also may have a problem in the ruleset, or the device isn't getting updated. Try running the usb_modeswitch command, then run wvdialconf.

Hi,

Again I tried the below..

1. Installed Redhat 6.4

2. Installed wvdial, usb_modeswitch-data, usb_modeswitch packages

But still I am not able to connect to the internet. Still I'm getting the below error...

I am unable to find where the problem is..
Now, i did not used the usb_modeswitch. Is there any problem with the nameserver IP's which I mentioned above..

Which you SHOULD NOT DO unless you are PAYING FOR IT. And RHEL is not a good distro to use for 'consumer' hardware..it is meant for SERVERS, which typically don't have devices like this, blutooth, sound, etc.
Great...and did you actually RUN the usb_modeswitch command???
...which was EXACTLY what you had before, so there was NO NEED to do a reinstallation. What was the point?
If you don't use the modeswitch command, the device WILL NOT act like a modem, period. You did a complete re-installation for NO REASON, when all you had to do is run usb_modeswitch, then run wvdialconf. That was told to you very clearly before.
No idea, since we don't know who you use for internet...call them and ask.
