Unable to connect to internet !!!


Hi friends,
This is a very peculiar problem I am facing.
I am using Fedora 10. I use my mobile phone Nokia 5300 as a modem for surfing the internet. I had edited the wvdial.conf file to have my mobile configured as a modem using data cable.
Now when I am dialing for internet access, my mobile phone shows that internet is connected. But when I am launching Firefox, it is showing "Firefox is offline". Again when I am trying a system update,it shows "No network connection". I even tried to install RPMFusion trough the terminal, yet the message was "Unable to connect".
Please help me connect to the internet.
Thanks in advance.

Check your firewall ... install Guarddog for GUI configuration of the same.

If your connection keeps fluctuating then
this may be due to the way Fedora 10 handles CPU scaling on some systems.

But the connection is all along steady, I am getting an "E" on my mobile showing edge connectivity all along. Firefox has not been able to connect for once.
And about the firewall, how can I disable it.

Is firefox in offline mode ... check?

First you need to stop SELinux with

#su
#setenforce 0

then you can configure your firewall (but usually it is not essential)

Try

#ping www.google.com

Post output of

#ifconfig -a

#netstat (relevant portion)

My machine is connected to the "Students Network" in my hostel through 100 Mbps LAN, so I have an ip 192.168.0.240, netmask 255.255.255.0 and a default gateway 1.1.1.1 .
But ethernet won't affect the dial up internet through mobile phone...will it? (Well I am new to this system, I am not sure).

Some new developments I found out :

this command "curl http://74.125.77.103" provided me a html code.
the ip is of www.google.com.

When I gave this command "ping 74.125.77.103" pinging was successful.

When I put "http://74.125.77.103" in Firefox browser the google homepage opened up. But if I typed www.google.com in the firefox browser it shows "Address Not Found".

Please help me connect to the internet....

then you need to add the DNS from your provider in
/etc/resolv.conf

nameserver xxx.xxx.xxx

Ifyo don't know the DNS from your provider, you can use openDNS

nameserver 208.67.222.222
nameserver 208.67.220.220

Dear Repo I tried out the open DNS, it didn't work. Firefox says "Address Not Found"
I got the DNS of my service provider,but it didn't work either.
I am just providing the terminal results after I connected by wvdial. See if that contains any info.
