unstable network connection

Asked by Bruno

Hello. I installed Ubuntu 7.04 and, since the first kernel update, my network connection is unstable. But thins got really worst when I installed the latest kernel update. Now my IM clients are always disconnecting, I stay about a minute with no access to my home network, I have huge timeouts while surfing the web and I'm having an hard time with torrent downloads.

I already exchanged the network cable and even connected it to another port in the router.

My network card is an Nvidia nForce2, I'm behind a router and I'm not using a firewall in Ubuntu. If you need more info, please tell me.

Thanks for the reply. :)
I don't think I'm using IPV6. At least, it doesn't seem. But I'll try your tip.

My connection is slow, too slow. I often have to wait 30 seconds and more so I can open a website. After that, the websites open normally.

Forgot to say, my connection became terribly slow after disabling the IPV6

I just opened my /etc/network/interfaces and I saw this:

auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

#auto wlan0
iface wlan0 inet dhcp
wireless-essid CASA_
wireless-key XXXXXXXX

#rt73 wireless network device using DHCP
iface rausb0 inet dhcp
pre-up ifconfig rausb0 up
wireless-essid CASA_
wireless-key XXXXXXXXXXXXXXXXXXXXXXXXXX # This line for

wireless-key s:XXXXXXXX # This line for ASCII

auto rausb0

I reinstalled Ubuntu, but the problem remains, although with less frequency

Finally I found a solution, thanks to the Portuguese Ubuntu Mailing List.
I edited the /etc/network/interfaces, and only left this entrances. Now it works perfectly.

auto lo
        iface lo inet loopback

auto eth0
        iface eth0 inet dhcp
