Mobile internet

I have Suse 11.2 installed in my laptop. I have mobile internet connection from Tata Photon +. It was configured using wvdialconf and wvdial. This connection plays hide and seek game when I use wvdial.
The problem is every time I plug in the dongle it gets mounted at different points like
ttyACM0,ttyACM1…ttyACM7.
Most of the time the following message comes:

linux-ab5h:~ # wvdial

unfortunately nither wvdial and pppd man pages give any solution.
Can I get some help?
Thanks in advance.

1st, you’ll want to disable all of the lcp* features in your ppp options.
From my experience, using a tethered connection where the phone shows up as a
modem, you have to disable lcp in order for things work. Still, your phone
company likely will disconnect the connection when idle. I just set my
connection up to reconnect on demand.

2nd, handling the DNS issue is a matter of setting up a resolv.conf that works
with your provider… or running your own caching DNS (BIND named) and using that.

I have exactly similar problem (as described in the first post ) with using TATA Photon on OpenSUSE 11.3. Adding “Auto DNS = off” in /etc/wvdial.conf and/or adding the nameserver ip s in resolv.conf - nothing works.

Before the connection times out , I tried to ping several other nameserver ips (that work with my other net connections) , but all displayed “Destination Net unreachable”.

This is turning out to be very frustrating. Can someone please help us out ?
