Context

I have purchased a new Dell XPS L502x laptop which has Windows 7 Home 64-bit which has this Wi-Fi Option: Intel ® Centrino ® Advanced-N 6230 (2×2 agn + Bluetooth)

And I have 4 Mbps Internet connection with a D-Link DIR-655 Wireless router.

Problem

When I use internet on my laptop by wired LAN it works very good very fast. But when I use internet on Wi-fi it works very slow, and most of the time it doesn't work properly.

Any solution for this?
