Sporadic/slow/non existent internet connection-Something wicked

Downloaded Ubuntu 12.04 boot image. New install x64. I have reinstalled 3 times both x64 and i386 all to no avail or internet connection. All worked perfectly with 11.10. Have a dual boot system with win 7 x64 and ubuntu 12.04 on same sata drive. Win 7 internet works perfectly. What is going on????
