Ubuntu Gutsy and the Internet

Wow!

I installed Gutsy Gibbon this Friday. Finally it worked like a charm. Even my resolution was set properly. I have a Dell Inspiron 6400 (aka e1505) and I have to say I did expect this
What I did not expect though was not being able to browse the internet on my wireless network.

Basically everything would simply resolve to 10.1.1.1 and my browser would just not work.

To cut long story short what I had to do was to first switch off  IPV6 in Firefox's (open new tab -> type about:config in the URL bar and hit Enter -> type IPV6 and then dbl click to set option to disable). Then I realized it was not enough My DNS servers were messed up.

Initially I put the correct DNS value (from my ISP) in  System -> Administrator -> Network -> DNS and though the internet worked the values were lost after a reboot.
Apparently the NetworkManager overwrites the /etc/resolv.conf. Oh well, there is not much one can do about that eh? When I was about to give up I discovered a file called: /etc/dhcp3/dhclient.conf
At the top of this file there is a line like this:
#prepend domain-name-servers 127.0.0.1;
All I had to do was to uncomment the line and replace the IP with my DNS. After I rebooted I checked the /etc/resolv.conf and my DNS was there.

I believe this problem is quite specific to some Wireless Routers / Modems. Mine is a D-Link and I suspect other people have the same problem as well.

I hope a future update will fix this problem.

Cheers…
