Internet Connection Dies Every Once In A While...

[mc-rpg]

My internet connection in gutsy dies every once in a while, it drags down my internet experience. It could be working right now and die for a moment and then it works after a while, briefly moments, it makes my browser take too long just to load a web page, because the connection is death most of the time and when it work is just for a few seconds. What's wrong?

soccerboy, In my case is my normal internet connection, not wireless but it seems that it affects wireless connections too.

It seems that it was something with the IPv6 support, I disable it and everything seems to be fine until now. It's weird because i hadn't this problem in the past versions of ubuntu (Dapper or Feisty), can someone enlighten me?

If you want to disable IPv6 to get better internet connection speed just edit the aliases file
sudo vim /etc/modprobe.d/aliases

and change the line: alias net-pf-10 ipv6

to: alias net-pf-10 off ipv6

Don't forget to reboot!

To check if IPv6 is running use the following command
ip a | grep inet6

I will post it here if it wasn't the problem, I hope you do the same :)

I lose the wireless connection every once and a while, but the eth0 connection stays up. This is new to me since the dist-upgrade on Oct 5th. I've never had a network connection problem before then, and I've been running 7.10 since September.

One thing I don't understand about every linux distro I've run is that even if you have 2 network connections, linux tends to only use one of them until it fails, then it switches to the other. To me that seems not very smart, especially if the connections are through different servers -- if the network manager divvied up the loads via both connections, it could potentially avoid a bottleneck.
