Re: Fedora seems to be connected to the Internet... but it's not.

As soon as I sent my last email I figured out what's wrong. :P Just to
test something out I Entered in Google's IP address and it worked! So
I think I've got a DNS issue here...

So, I just installed Fedora 12 onto a current model 15" MacBook

it's connected to the local network just fine, but I'm having a
little
trouble with the Internet. I can download new applications from the
repositories, so I AM on the Internet, but it appears that the only
website I can visit is Fedora's website. I cleared the cache and
tried
again and could still go to
<URL:http://fedoraproject.com>fedoraproject.com, but if I try to
go to any
other website, Firefox tells me I'm not connected to the Internet.
I'm not
an expert at Linux, so I would like to stay away from the command
line if
at all possible.

I see two possibilities:

1) You are not connected to the Internet. When Firefox detects that
there is
no network connection, it will serve pages that it previously
cached, out of
its cache, but when you try to load a page that it has not cached,
it will
tell you that you're not online.

2) Firefox is not correctly detecting your network status, and
falls back to
offline mode, leading to #1. From the "File" menu, uncheck "Work
offline",
then try to browse to www.cnn.com, www.yahoo.com, www.foxnews.com,
any page
that you have not visited yet.

In relation to (2), Firefox detects it's online by asking
NetworkManager. If NM thinks it's not online, that's what FF believes.
NM will say it's not online when it's not managing the interface, even
when the interface actually *is* online. The solution is to check the
appropriate box in system-config-network.
