Wired Connection not connecting to router

[SeanW95]

Hello I've recently installed ubuntu on a 20GB partition using the windows based installer. I booted up and It won't connect to my network( Ethernet direct to router/modem AIO unit.)I've been talking in the IRC which had alot of help but no solutions. Any help?

To give a little background I like to think I'm quite proficient in the windows environment and currently on my last year studying a BTEC IT course (Level 3 extended diploma) and this is my first time on linux without suppourt from a tutor. I wanted to get a feel for linux and have very little knowledge of linux.
I'm running Ubuntu 12.10

EDIT: Information such as ifconfig is in the posts below!

Edit : installed without wubi still same error. It says connected but I can't ping my router

[Warren Hill]

There are lots of reasons for possible problems and we need more to go on
open a terminal (CTRL+ALT+T) and enter the following it may give us a clue

lsb_release -a; uname -a; sudo lshw -C network; ifconfig; route -n; cat \etc\network\interfaces

Post all the results back here and we may be able to advise further

Looking good so far. Try

ping -c5 192.168.0.1; ping -c5 8.8.8.8

Does it make any difference that my motherboard is a Nforce 630a chipset? and here are my ping results.

Hi

this route looks suspicious

0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 eth0

Normally where it says 0.0.0.0 I'd expect to see "default" but I would expect this to work too.

Also because you're getting unreachables from your own ip we know that your machine doesnt know what to do with these pings which indicates a routing/default gateway problem.

We can try remove this suspicious route and adding it back again correctly to rule it out as a cause. Just fire up a terminal and run:

route del 0.0.0.0
route add default gw 192.168.0.1

Hope this helps!

I don't know about that...my routes look similar to the problematic ones and I'm having no problems with my connection. The only thing different is the metrics and the interface.

route -n:

And just to ask the obvious question, your router is setup to respond to pings?

[SeanW95]

Command didn't work...and yes my router responds to pings

sean@sean-ubuntu:~$ route del 0.0.0.0
