I purchased this *www.flipkart.com/tp-link-150-mbps-tl-wn721n-wireless-n/p/itmd8rrpdjyrtcwn?pid=USBD8RRP4ZEZVS98 for the sole use of a wifi hotspot as i already had an internet connection via the lan cable , initially i got it replaced from flipkart since the hotspot feature wasn't working, the replacement arrived yesterday and it still has the same problem, the wifi receiver is working fine but for some reason the hotspot feature isnt, i am able to connect to the hotspot but cant access the internet through the hotspot, its driving me nuts for the past 7 hrs, have used many hotspot softwares like connectify, virtual router, mhotspot, but no solution, even created the windows 7 ad hoc connection but still cant access the internet......god knows whats the problem whether the device is faulty again or something else. Please help me guys this problem is killing me
