|The first thing you're going to want to do is to see if there's a more up-to-date driver for the wireless interface on your laptop. If there is, download and apply it.|
If that doesn't fix the issue, or there isn't a newer driver, contact Sony support. If it's new, it should still be under warranty and that means they have to fix it for free.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
