Wireless connects successfully but not working

[genbuntu]

Hello

I'm having problems with my wireless connection through Ubuntu (Hardy). I can connect successfully to my home wifi router but I can neither browse nor ping anything (tried google and router ip) . The wired lan works fine though.
My wireless card in the laptop is pretty common and I did not notice any problems with Ubuntu Feisty . Nor did I ever require / manually install any sort of restricted drivers. Here are the specs from "lshw" command:

description: Wireless interface
product: PRO/Wireless 2915ABG Network Connection
vendor: Intel Corporation
physical id: 2
bus info: pci@0000:06:02.0
logical name: eth1
version: 05
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=ipw2200 driverversion=1.2.2kmprq firmware=ABG:9.0.2.6 (Mar 22 2005) latency=32 maxlatency=24 mingnt=3 module=ipw2200 multicast=yes


From what I've troubleshooted , the problem seem to lie in some setting / configuration in Ubuntu (Hardy) because when I boot into WinXP , it works fine.
Any ideas / suggestions ? :)

its better to disconnect wired when trying wireless and vice versa
