after you connect ping the DNS server and post the output here. If your DNS server is 61.1.96.69 then open a terminal and type

ping 61.1.96.69

and press ENTER

See if any packets are being dropped.

If yes, in your network config, set the gateway as 192.168.1.1 and enter the DNS servers. If you do not know your DNS numbers ask your ISP or use open DNS - 208.67.222.222 and 208.67.220.220

packets are not dropped ,

Try setting the gateway manually as 192.168.1.1 and enter the DNS servers. If you do not know your DNS numbers ask your ISP or use open DNS - 208.67.222.222 and 208.67.220.220

and restart the network or reboot

Hi I got the net on Ubuntu 7.1, with Reliance Data card, Huawei EC325, during many days. Now, I can not.
PPP daemon has died = A modem hang up the phone (exit code = 16). Var/log/messages = warning: secret file /etc/ppp/papsecrets has world and/or group access.
Please, can u help me to reconnect ?

i think the ip is 192.168.1.1
so ping 192.168.1.1 in DHCP mode. try pinging the gateway
