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 220.127.116.11 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!
