losing Internet repeatedly

[flamboyant]

i'm losing access to Internet every few minutes, so i restart my ASUS AM602 ADSL modem and then everything works again until next interruption. i don't have this problem on Windows.

/etc/network/interfaces:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1

/etc/resolv.conf:

nameserver 192.168.1.1

what might cause the problem?

Quick thought... it appears you're relying on complete manual configuration of your networking stack. While there's nothing wrong with that, I wonder if any of Precise's automatic network configuration tools might be clobbering your manual setup? I ask because I actually don't know, but it might be worth investigating. It's possible that given your configuration, utilities like Network Manager, dnsmasq, dhclient, and resolvconf will need to be disabled in some way.

Have you tried with this:

thank you guys for your replies. i reinstalled Kubuntu and set up a connection with the static IP addresses in Network Manager. it works.

before long the old problem was back. eventually it turned out to be either incorrect settings or malfunction of the router in the combo. as soon as the unit had been configured as a bridge the problem was finally solved.
