I installed ubuntu to my old machine p4b533 but it keeps asking for a network password, tries to connect then disconnects. Now if i assigned a static ip it connects with no problems but cant even ping my router but it says it successfully connected. Is this a bug? What is the fix for this?

It seems link the router DHCP doesn't provide IP. Are you sure DHCP is active in router? Have you tried from another device/machine? –  Sneetsher Feb 9 '14 at 17:53
Yes i can connect to my router using my laptop and android phone. I even set the encryption of my router to WPA, the desktop ubuntu can connect to it but can even ping my router or any other ip/website. By the way my USB wireless adapter is using a WPS button if that helps determining the problem. Thank you so much. –  elcabronel Feb 10 '14 at 0:24
