Take the refund... Do not buy the Tp link from flipkart.... Or any other online site,everyone has listed specifications of v2,buy the online sites are selling v1 hardware which has 3dbi antaenna, i can get you the v2.. Brand new sealed. Lemme know.I have asked flipkart for replacement as this new hardware is buggy and its not just me I have asked them to replace and give me TP link 8968 not sure whether they would agree or not.
Flipkart does not offer refund as far as i know I have ordered for replacement if the second router also does not work then I'll get them to give me TP Link
