I have Ubuntu 14.10. When I'm at work I can browse the internet without problems. Now that I'm at home, I can connect, but I'm not able to browse the web.

Some informations:

the output of ifconfig:

marcosh@marcoshstudio:~$ ifconfig

          inet addr:  Mask:

I am using network-manager, and this is the output of nm-tool:

marcosh@marcoshstudio:~$ nm-tool

  IPv4 Settings:
    Prefix:          24 (


I am worried the somehow the settings in the file /etc/resolv.conf are interfering:

marcosh@marcoshstudio:~$ cat /etc/resolv.conf
domain mva.local
search mva.local

Is that possible?

I know (since I did that another time) that if I remove and reinstall the network-manager, I will be able to browse from home but not from the office. How can I avoid this and solve my problem once for all?


Eventually I solved it using

sudo dpkg-reconfigure resolvconf

see this for more informations
