Why can’t I using my normal connection but when I use Tor network it works?

I’m using mobile broadband (ppp).

I tried to ping www.google.com but the result was

mrahimi@CQ40:~$ ping www.google.com
ping: unknown host www.google.com

Has my ISP banned me or is there some other problem?

I have disabled my UFW firewall but still have the same problem.

$ cat /etc/resolv.conf
# Generated by NetworkManager

I tried using the network proxy (using Chrome) and the internet worked normally, but when I use the normal connections I again have no connections. Does this mean I have been banned by my ISP?

Looks more like a DNS or firewall problem. What is the output of cat /etc/resolv.conf and are you running a firewall ? – bodhi.zazen Dec 22 '11 at 20:31

You need to configure DNS . Usually your DNS is provided by your router (192.168.0.0 ? )

networkmanager

Try using the google dns servers 8.8.8.8 and 8.8.4.4 (set them in network manager) code.google.com/speed/public-dns/docs/using.html – bodhi.zazen Dec 22 '11 at 21:39
    
Can know why this happen? If you don't mind? – fly_high_hahaha Dec 22 '11 at 22:01
    
I am not sure, unless you manually configured your connection, something about your mobile broadband setting an IP abut not a DNS. I do not have the hardware / IP provider to test. Perhaps someone else will know and we can both learn. – bodhi.zazen Dec 22 '11 at 22:08
