Wvdial connect but no ping or Internet

Asked by Digitallad

Hi I am a newbie.
Problem: I can connect with my GPRS modem with Wvdial but cant ping a adress or go on the net with firefox.

Here is the connect log:

To run a command as administrator (user "root"), use "sudo <command>".

See "man sudo_root" for details.

It sounds like you are missing the default route. Do the following after connecting and see if it helps:

sudo route add default gw 192.168.100.101

(Or whatever the remote IP address is.)

I would suggest using gnome-ppp instead. It is a frontend to wvdial and works wonderfully for me. You have to enter the values from your config files and just hit "Connect". You should run it as root, though, so it can change resolver settings and add the default route. The most convinient way to do this is to add a menu entry, or copy from the main menu, with the following command line:

gksudo gnome-ppp

Henning

Hi Henning
Thank you for the info on gnome-ppp.I finaly got it installed on ubuntu.
I used your
sudo route add default gw 192.168.100.101
command and I could connect to the net for about 1 min but it doesnt work any more even if I redo the command.

I istalled "gnome-ppp_0.3.23-1_i386.deb" with the "gnome-pppfixedforgutsy_0.3.24-1_i386.deb"

Then inseted all the settings into the setup.
Problem: It again dials and connect but still cant ping or go on the net.

What am I missing?

You do _not_ need to do the "route" command, if gnome-ppp is configured correctly. Check the Options tab in the Setup to see if the Option "Check default route" is active, as it should be.

Please send me the output of the following commands (when connected):
ping www.google.com
ping 209.85.129.104
netstat -rn

Do you have another network connection up while trying to connect through the modem?

This should be solved easily ... I hope ;-)

Yes I have a network cable conected to the pc. I also have a router connected to the network but it doesnt supply Internet only DHCP.
I disconected the cable when I did the 2 nd conection test but with the same results.

Also I noted that when it shows conected the counter runs much faster that it should ie. 5 min in less than 1 min real time??

Thank for all your input!

Now I see much clearer!

The option is called "Check default route" because it only sets the default route if none is set. But you have a default route to "192.168.0.15", so none gets set by gnome-ppp.
Remove the existing default route by clearing the entry for the "gateway" in the settings for the cable network connection. If 192.168.0.15 is not an internet gateway, there is no need have it as a default gateway.

This should do it, now gnome-ppp can set the default route once it's connected.

Have fun surfing!

That is one thing I have to get working on myself. I have a Treo650 and
Bluetooth on my notebook and I hope to be able to sync it to evolution.

Let me know how you do with that.

Hi guys,
I have an additional question. I had the same problem and thanks to this post I was able to solve it.
But one thing causes me some headache.
* I use cable/wifi connection mentioned above by default.
* This only works for me when I apply the "sudo route add default gw my_ip"
* Alternately I need to connect sometimes with gprs modem on my nokia 6300.
* Can use my nokia somehow without removing the default gw of my cable/wifi connection?
It is pretty annoying all the time removing it and then puting it back.
* Can you see some workaround for this?

Thanks for reading my post.
