EDGE wireless modem cannot resolve IP name
I am using EDGE wireless modem VE900 on my development board with linux2.4 on it.
I am using "pppd" and "chat" to establish GPRS connection.The GPRS connection is successful , "ppp0" is up , i got the IP address DNS etc.
But I cannot ping to any web site straight away like
"ping www.google.com".Error returned is "Host lookup failure".
I need to give the IP address like 192.17.x.x , then only it replys.
I understand that there is some issue with DNS.But I have provided the DNS address in "/etc/resolve.conf"
