[SOLVED] Wired ATT connection

Tikhon03 · #1 29th April 2011, 09:29 PM

First, let me just say that I am not entirely sure if this is an ATT problem, or a problem with my settings in Fedora.

I have 5 operating systems installed on my laptop: Windows XP, Kubuntu, Fedora, Mandriva, and OpenSuse. All 5 of these operating systems show that I am "connected" and that my wired connection is "active." But when I try using my browser to get online, only Windows and Kubuntu are successful at doing this. In the other 3, e.g. Fedora, I can not get online.

Now you could say, "so you have it working on two operating systems, therefore you can get online - no big deal." Yes but those operating systems are Windows and Ubuntu! I would prefer to have things working in Fedora. If you think that this could be an issue with my settings in Fedora, could you please let me know? Thank you.

If you are referring to the Firefox browser, then try disabling IPv6 in its configuration. No promises, but it is a common thing. It's easy to try and reversible, so it will harm nothing to try. Start Firefox. Enter about:config in the URL box. Agree. Scroll down to network.dns.disableIPv6. Right-click the property to toggle it to "true". Try browsing again.

Wow! That worked. Thanks a lot! It makes me wonder though. Is there anything similar that works for the other browsers? And why were there no problems in Ubuntu with that setting as False? (I Checked that) In any case I am very pleased!

Maybe it's KDE doing things better than Gnome, maybe Ubuntu is doing it better than Fedora....

In many cases you really can't tell why it's working in one and not the other without some real digging.

Apparently, however, you were having the same issue with Mandriva and SuSE, yes? Mandriva also uses KDE by default, not sure about SuSE, so that probably eliminates the KDE/Gnome theory.

It may be different default firewalls. As I said, it could be many things.

more likely they have IPv6 disabled in the kernel. Either that or they have IPv4 referenced before IPv6...

The problem I usually read about with IPv6 is due to the long timeout for lookup errors. By the time IPv4 is referenced, the timeout has happened, and the transaction aborted. Disabling IPv6 removes the timeout, leaving an entire timeout period for IPv4 timeout errors.

@jpollard: That's quite interesting.
@smr54: Believe it or not I am using KDE on all of my Linux systems (Fedora included). I just like KDE better than Gnome.

Ok, based on what jpollard has said above, I decided it would be a good idea to disable the ipv6 module in Fedora, rather than in Firefox. The original suggestion by stoat works for Firefox, but only for Firefox. Other programs such as Konqueror, which I like using for ftp, and various programs in the KDE system settings, were not able to access the internet either. So rather than trying to disable ipv6 for each one individually, doing it all at once seemed more practical. Instructions on how to do this for fedora 12/13 can be found here:

The method for previous versions was different, and who knows whether this will still work with future versions. I found quite a few out of date descriptions of how to disable ipv6 in fedora, before finding this blog post. In any case, everything works now. Thanks, again for all of the help.
