one user's firefox internet connection is fast

achim_dublin · 09-19-2007, 07:05 AM

Hi,

I have a fresh install of Mandriva 2007.1 connected to the internet through an ethernet connection to a netopia router (eircom DSL broadband in Ireland).

I am struggling with a really strange problem: I have no problems whatsoever when I connect to the internet through firefox (2.0.0.3). However, if I am using epiphany or konqueror or if I am trying to connect to the internet as one of the other users on this computer, the connection is running slow as a dog. This happens for identical webpages, so I know for sure that the problem is here at this end.

I have disabled IPv6 (inserted the line

NETWORKING_IPV6=no

into the file '/etc/sysconfig/network' and I have also tried disabling TCP window scaling (as suggested here, but to no avail.

I guess that it is some setting in one of the configuration files in my home directory (other users also experience extremely slow internet connection when using firefox), but I do not have a clue where to look.

Any help would be very much appreciated.

Hi,

when I go through my /var/log/messages, I am stumbling across the following line:

Code:

Sep 20 09:05:01 localhost ifplugd(eth1)[3388]: client: Failed to open connection to system message bus: Failed to connect to socket /var/run/dbus/system_bus_socket: Connection refused

eth1 is the active connection that I am using to talk to the outside world. Would this possibly point me towards a solution of my problem?

Hi,

I now think that the problem has to do with IPv6 (although I do not yet have a general solution to it). In my personal Firefox profile (accessed through typing 'about:config' in the address bar), the entry

network.dns.disableIPv6

was set to

True

In everybody else's profile on this computer, it was set to

False

Now I have at least managed to enable everybody else to access the internet. However, there is an underlying problem left, that causes Konqueror and other browsers to still try and negotiate IPv6 protocols. For some reason, disabling IPv6 networking in /etc/sysconfig/network (as mentioned in my original questions) appeared not have done the job. Anybody any suggestions?

Help would be much appreciated.

Maybe its another dns problem (as i suggested to another thread?

Hi Bilko,

From the little that I understand about networking, I believe that the IPv6 problem is at the end of the day related to the DNS servers that do not speak IPv6 (I might be terribly wrong here). However, I think that my computer is aware of its DNS server (resolv.conf contains the IP address of the router and the router is pointing to the two correct DNS servers).

Also, if there was an underlying DNS problem, I don't understand, why firefox is running ever so smoothly (including all sorts of plugins), as soon as IPv6 is disabled... ?

Thanks for your contribution,

Achim

I think it's a driver-specific problem.
Maybe you should install the latest driver packages from cooker and see if the problem has been fixed.
