I have a broadcom device using dell laptop that can dual boot into windows 7 and ubuntu 12.04 LTS. I have no trouble connecting to the internet using the Windows 7 side, but on Ubuntu firefox and chrome both hang on loading on startup for a bit and then give me the "webpage is not available" page with this error and some suggestions at the end: 

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 access.

I can however use terminal and ping 8.8.8.8 successfully.

Oddly enough, when I'm on campus/ in my work building I can access the internet just fine through ubuntu and windows 7. Which leads me to believe it is some issue with my wireless router or my network configuration.

I have a LINKSYS WRT54GL. 1 other laptop and ipad that can successfully use wireless, a wired PC also connected to the router. My router setup uses DHCP with a cable modem.

I have tried using these commands related to DNS with no luck ;

/etc/init.d/dns-clean restart

/etc/init.d/networking force-reload

sudo /etc/init.d/dns-clean

Also for some additional perspective; I could use wireless just fine at home on the ubuntu side up until about 1-2 weeks ago when I started having this problem. I also use a VPN app to connect to my work's network. I can't recall doing anything differently from the past 1-2 weeks. The only changes I can remember are running the usual updates that Ubuntu prompts me with through update manager.

Any help would be much appreciated!

The resolv.conf was probably changed for VPN use and was not changed back for normal use as a result of the crash. Deleting the old resolv.conf may help. You can make a backup copy of the file and delete the original with this single command:

sudo mv /etc/resolv.conf /etc/backup.resolv.conf

A new resolv.conf will be generated as and when needed. See the answer to the following question:

Internet connection not working although it says it is connected

Hope this helps

  • Thank you! It worked, however the file was named resolv.conf and not resolve.conf. Nonetheless thanks for the help, do you think this can be avoided as long as I always turn off the VPN before shutting down? – Tenzin Aug 09 '12 at 17:47
