Hi all,

I recently noticed that my internet connection is too slow. I supposed
that it was because of my ISP but I tried to switch to a newly created
"fresh" user, and it turns out to be that with this fresh user the
internet connection works very well. So I guess that this is due to a
config for my user. I tried with another browser and it's the same. I
did /sbin/ifconfig and the output is the same for both users.

I have running the network monitor in my KDE desktop. What I see
typically is that with the old (bad functioning) user I have spikes of
high bandwidth connection (reaching 300 KB/sec) intermixed with
periods of very low bandwidth (<10 KB/sec). This is consistent with
what I see when try to see a video or use Skype. There are moments
where the system works fine, followed by moments where the connection
is very bad. Here there is a capture of my bandwidth



When I see the same graph for the new fresh user the curve is almost
constant at 300 KB/sec. No spikes.

I considered to move all my stuff from the old user to the new fresh
user, but the truth is that I have a lot of config in my user so I
want to try to keep the old user.

I ask for help in finding what files are i charge of netowrk
configuration in KDE. I assume that this is in the KDE config, not in
the system, because for the new fresh user the network is working
well.

Specs of my system:
Fedora 20 (yum updated few days ago)
KDE 4.12.3

TIA, Mario

Please ignore my post. It was solved simply by cleaning the cache of
firefox and the cookies. I was confused because I had the same problem
with Chrome so I discarded a problem related with the browser.
