Network timeout when I turn on the Ubuntu machine

[Opsive]

Hello,

I did a search and my problem is similar to this thread, but I am unable to post replies so I am creating a new post.

When I turn on my Ubuntu machine, the entire network behind the Netgear WPN824v2 router times out whenever I try to connect to an external site or directly to the router. When I turn the machine off, everything starts to work again. What could be causing this? The Ubuntu machine (version 8 ) is hard wired to the router, and it has been working great for the past couple of months.

Per the suggestion in the thread I linked to, I disabled ipv6 but that didn't change anything.

Thank you,
Justin

go to the ubuntu machine and type ifconfig and post output

$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:01:80:5c:e3:7e

I forgot to mention that when I am getting the network timeout errors I can still connect to the ubuntu machine from a different machine.

Thanks for your help,
Justin

it could be an ipconflict.. is there any other router or pc having the same ip 192.168.1.3?

No, there isn't. I changed the machine to use a static address, and got the same results.

Are there any logs of some sort or anything that I can look at to see what is going wrong?
