Helo I am using Dell inspiron N3010(13R). It was with windows 8 but due to sum problem with windows i changed windows to 7 (32 bit) ultimate. Now prob is that wifi is not working in it and it is not allowing any driver to install. I had installed win 7 thrice but prob is same. The IT man is asking to claim warranty as this is the issue with laptop. Please suggest as wifi was working fine in win 8.
