Hi starman,
Welcome to Sony Community!
What is the current operating system of your laptop? The network card installed in your laptop is Marvell Atheros AR9287 Wireless Network Adapter. Unfortunately, there is no available driver update for this adapter.
This OEM version of your network adapter is customized version designed as per the requirement of Sony with which it is shipped. This version has different features and compatibilities as compared to the one that they have on their website. This will not be compatible with what is installed in your laptop.
Regards,
Jen
