Problems accessing internet through wireless connection


Greetings

I'm a linux noob, and i guess i'm a wireless noob too, so probably this is a simple problem.
By looking at the ifconfig results it seems all the packets i get have errors, but i can't understand why.

My wireless connection (ath0) was auto-configured by the Ubuntu installer.
I can ping every address i tried, i can access the computers on my local network, but i can't access computers on the internet.
I know my router's configuration is good, because it works great on windows.

I'm using Ubuntu 5.04 with it's original kernel (2.6.10) and my wireless card is a 3Com 3CRDAG675 wireless card.

------------------------------------------------------------------
ifconfig results:

The only entry on my route table is "nameserver 10.0.0.1".

I would apreciate any help you can spare :-)

Well, my connection started working out of the blue
It takes forever to resolve addresses, but at least the transfers are fast...

WELL! TO START WITH... YOU HAVE A BIG PROBLEM WITH NETWORK BASICS.
AND I HAVE ONE PROBLEM WITH THE CAPSLOCK...

YOU JUST DONT KNOW HOW TO CONET 2 DIFFERENT NETWORKS.
YOU GET TO YOUR INTRANET, WITH YOUR IP RANGE 10.0.0.X

FIRST YOU NEED TO KNOW WHERE D INTERNET IS AT...?
AT THE ROUTER.
YOUR ROUTER HAS 2 IP NUMBERS, THE ONE THAT CONNECTS TO THE INTERNET, ANFD THE ONE THAT CONNECTS TO YOUR INTRANET.

SO, THE INTERNET CONFIG SEEMS TO BE ALL RIGHT, BECAUSE IT WORKS WITH WINDOWS.
ONE QUESTION, DO YOU KNOW THE IP OF YOUR ROUTER...? I THINK IT WILL BE 192.168.0.X
PROBABLY 1 THE LAST ONE.

SO... ROUTE ADD DEFAULT GW 192.168.ETC ETC ...
AND CHANGE ALL YOUR IPs TO THE SAME RANGE.

IF YOU THINK ALL THIS IS NOT NECESARY...
OPEN A BROWSER, TYPE IN THE ADDRESS BAR.. 216.239.39.104

IF GOOGLE APPEARS.. THEN YOU HAVE INTERNET, BUT NO DNS.
AND THAT IS ANOTHER MATTER...

LET ME KNOW HOW IT GOES.
