My dial-up modem is a Conexant HSF. I installed its drivers and dialed with wvdial.
and it outputs :
# wvdial
--> WvDial: Internet dialer version 1.60
--> Initializing modem.
--> Sending: ATZ4
ATZ4
OK
--> Modem initialized.
--> Sending: ATDT1250
--> Waiting for carrier.
ATDT1250
CONNECT 115200
--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Sun Mar 15 18:09:36 2009
--> Pid of pppd: 30402
--> Using interface ppp0
--> local IP address 112.134.52.182
--> remote IP address 203.115.1.143
--> primary DNS address 222.165.160.2
--> secondary DNS address 203.115.0.46


BUT I cannot access to internet by Firefox or Lynx. Not even yum install .

What could possibly occurred ???
Appreciated if anyone could feel free to help me.

Can you ping to DNS server IP address? Use ping command at a terminal:
Code:
ping dns-server.ip.com
ping 222.165.160.2
Make sure firewall is disabled:
Code:
/etc/init.d/iptables stop
Make sure /etc/resolv.conf has ISP dns server address:
Code:
cat  /etc/resolv.conf
Verify routing:
Code:
netstat -nr
Now try to ping ...

I added to resolv.conf nameserver 222.165.160.2
iptables stopped.
But I cannot ping. What should I do ?

ping gives this :
