Strange (and big) problem with internet in kubuntu 10.04

[Mr.Cookie]

Greetings Everyone,
I have installed kubuntu since 3 weeks and until yesterday all works well.
But yesterday internet go off (I don't know for what reason but here sometimes internet go off, atleast once a week) I have restarted my kubuntu but recognized no more the network
So now to Work online I need to give (everytimes I turn on my pc) these commands:


ifconfig eth0 192.168.0.14 up
route add default gw 192.168.0.1

somebody knows the reason of these problem and a possible resolution (without the scripts)
P.S
I belive that may be I have installed some updates incorrect but I don't know It's only a guess

Are you using knetworkmanager or some other network management?

Is this wireless or wired?

This happens to me sometimes. Turn everything off. Computer, router, and modem. Leave them off for a few minutes. Then power them back on starting with the modem, wait until it is fully booted, then turn on the router, again wait until it is fully booted, then turn on the computer. The problem has to do with DHCP leases that are not being renewed and contain old information. This always works for me.
