I'm willing to bet that Ubuntu does not have a glaring bug that prevents anyone from using a wireless network. I don't use the software, but I still know somehow that that would never get released. And there isn't anywhere close to enough information provided in your question to actually help you solve this problem. –  Cody Gray Apr 30 '11 at 16:09

We need to know what wireless chipset you use. Please update the your question with this info. You can find out by opening a terminal and doing: lspci -v | less and pressing space to page down. –  boehj May 8 '11 at 16:37
