can't get connected on Ubuntu

[grandzu]

First of all, hi :)

 

I believe I'm a super noob. I can't get connected to the net in ubuntu. I've tried DHCP and static IP as well. None of it works. I can't ping my router. I've set my IP, gateway, mask in ifconfig and... it does't work. Those settings are good, couse I'm working right now on Win XP. But what is strange, the dhcp dosn't work too (It should, right?). Could somebody help me please?
