TATA USB Modem on Mandriva Linux 2008

Hi all

I am having problem configuring TATA USB Modem on Mandriva Linux 2008, although it runs without any problem on Open SUSE 10.3 and 11. The configuration in both Open SUSE and Mandriva is same. Can anyone help me out?

Sorry we don't navigate nowhere, you want an answer, you have to ask the question here, not put it on some forum and re-direct us there.

here is the full problem and workarounds I have tried:
(Ctrl C+V directly from link above)

Hi all,
I am trying to use TATA Indicom CDMA USB modem on Mandriva Linux 2008
using wvdial.
I have edited wvdial.conf file as per company's suggestion and it looks as follows:
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
stupid mode = 1
Modem Type = USB Modem
ISDN = 0
+FCLASS = 0
Phone = #777
Modem = /dev/ttyACM0
Username = internet
Password = internet
Baud = 460800

I know it works because I have used it on Open SUSE on same computer and have
got no problems.
On Mandriva, when I run wvdial and then disconnect using Ctrl+C, I get following
output:

[root@localhost kedar]# wvdial
--> WvDial: Internet dialer version 1.56 (abuild@mandelbrot)
--> Cannot get information for serial port.

If I ping primary or secondary DNS, I get following output:

From 121.245.41.169 icmp_seq=1 Destination Host Unreachable
--- 203.197.12.30 ping statistics ---
0 packets transmitted, 0 received, +48575 errors

On one blog I found that wvdial requires a file /etc/resolve.conf with IP addresses of
primary and secondary DNS. I manually created the file but problem persisted. I have
also tried adding the two IP addresses in hosts file using Mandriva Linux Control
Centre, but no solution.

What is happening ? Because of this I am not able to connect to the internet.

I tried using kppp in Open SUSE and my internet connection was running fine there. So I set up the same settings in Mandriva 2008 and tried to connect. Once again I was not able to open any webpages.

Following are the messages I got in kppp:
Modem Ready
Logging on to Network

then in kppp's debug window:

ATZ
OK
ATQ0 V1 E1 SO=0 &C1 &D2 +FCLASS=0
OK
ATM1L1
OK
ATDT#777
CONNECT

Starting pppd

Then I get a pop-up from system tray
Network is up on interface ppp0

But I am unable to connect to internet.
Also I have found out from network monitoring programs that after the initial handshake not a single byte is transmitted or received.

What I think I missed was commenting out lines in link ifup-ppp script as provided in link by you (but there was no reason to do so in open SUSE) and I am using dynamic addresses (I am seeing correct primary and secondary DNS addresses in resolve.conf). But I will try these out too and let you know.

If you can get connected and still cant browse anything then it could be a problem with your DNS servers . I tried pinging it and it seemed to ping fine. Im nto sure how this works but another thing worth giving a try is using OpenDNS servers IP as a DNS server? Maybe you might have luck with that ?

No luck with that. I will wait till mandriva 2009 is released in october. I am using open SUSE 11 now.
