Internet Connection Dying

[Kasatka]

I'm new to Ubuntu, just installed it earlier today as a matter of fact. I'm using 5.04.

My internet connection dies after being connected for a little bit, it doesn't seem to die due to any specific actions. I have Windows XP on another partition, and the connection has always and continues to work fine, so it is an Ubuntu only problem. It is not caused by my cable modem or router.

I am using an onboard ALi ethernet card.

The fact that it works perfectly for a few minutes, then dies everytime, puzzles me.

Did you fully update everything(I think I read something about a buggy dhcpclient update?
Also try:

sudo ifdown eth0

and next

sudo ifup eth0

...it might tell you something about your problem.

sudo ifdown eth0:

sit0: unknown hardware address type 776
sit0: unknown hardware address type 776

Sending on LPF/eth0/00:0d:87:70:e1:e4

DHCPRELEASE on eth0 to 192.168.1.1 port 67

sudo ifup eth0:

Any suggestions, anyone?

I had the same problem with my internet configuration.

I´ve had to change my firewall settings and upgraded my kernel to solve this problem.

[Kasatka]

I am using the newest release of Ubuntu and I don't know how to access the firewall config file, or what exactly to change once I get there.

Also, I've noticed that even when my connection "dies" (as in I can't connect to anything using firefox, the autoupdater, etc.) GAIM still seems to work. Now that's wierd.

Please help, I'm dyin' here!

If you start firefox from your console, does it show any error messages when it "dies"?

PS: I know their was a problem with java popups in the past.
Using an other version should fix that.
