Finally I got rid of my BSNL Broadband.
Also got JioFi 2 few days back.
Now I need a wifi USB adapter.
So Bapun bro, should I go with iball as suggested by you?
Few days back I tried Tenda (don't know the specifications) from my friend but it's not detected in my Windows 10. It's working fine (Plug n play) with my friend's Windows 7. Any thought on this?
