I have been trying for many days to create a wifi hotspot with my laptop running ubuntu 12.04 and connect it to my windows phone7.5 based HTC Mozart. I have gone through many articles related to this, but none of them help. I create a wifi hotspot as suggested by some experts, but it isn't detected either by my phone or on other laptops. My laptop is Sony Vaio VPCEB14EN with these specifications .
