I have leoxsys nano wifi adapter 150mbps using chipset realtek 8188ETV. It works fine in windows but not recognised in backtrack or kali linux via vmware workstation 9/10/11. When i gave the command "iwconfig" it showed "no wireless extension" and in command "airmon-ng" it did not show any dirver or chipset.
All realtek chipsets are not well supported in linux, specially new and rarely used ones. You have to do a little research before buying a Wi-Fi adapter, if possible return it and buy TP-Link WN722N, this one has Atheros chipset and well tested with
Backtrack etc. Possibly you are fooled by
flipkart , be aware of cheap brands like
