About a month ago I installed the newest version of Linux Mint (14).
I use Linux the whole day on my laptop but every 1-2 hours my internet connection (Wi-Fi) magically disappears for about 10 minutes.
I get this error when I try to open a website in Chrome:

The server at google.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.

There is also no "ping" when I open the terminal.

I also have Windows installed on the same machine, but I never experience issues like this while using Windows.
When the internet is gone on Linux, it's still available on my phone over the same Wi-Fi. So the internet connection itself works perfectly fine.

Does anybody have an idea?

Look in /etc/resolv.conf when your connection is up and then, when it goes down, check again... –  jasonwryan Jun 2 '13 at 3:44

When this happens (during the 10 minutes of no Internet), run a few commands in a terminal window, as the root user or using sudo:

ifconfig -a - look for output concerning wlan0

iw dev wlan0 link


journalctl | tail or if journalctl doesn't exist, look in /var/log/messages

Something in that output should give you more to go on.
