I'm using Ubuntu 12.10. I can access the internet without problem at work via wi-fi, and I used to do that at home, but my internet provider changed my modem (which now has a native router) and things got a little bit weird.. I still can connect to my home network, my wlan0 interface gets an IP as it should, but I can't browse any websites or ping to any google servers; actually, I can't even ping my router.

With my phone and with another notebook (windows 7) I can access the internet via wi-fi without problems.

When I access the router with the windows note and browse the "Wireless Client List" tab, I don't see my linux notebook.

Here's some outputs:

Can you ping another computer on the network? (Keep in mind that the Windows firewall may block pinging) – Kupiakos Apr 2 '13 at 3:24
I can't, it says "Destination Host Unreachable", @Kupiakos – matheus.penchel Apr 2 '13 at 3:55
Hrm...strange. As a thought, is it possible to change your subnet to a 192.168.<nonzero> subnet? I've heard that can cause some funky stuff to happen sometimes. – Kupiakos Apr 2 '13 at 4:58
