Upgrade a wireless Broadcom BCM43142

QUESTION:

I have a vaio SVF14n11CXB with a Broadcom BCM 43142wireless adapter that I want to upgrade. Does anyone know if I can and what would I upgrade to? Thanks

 

SOLUTION:

This laptop SVF14N11CXB has an enclosed cover at the bottom part and everything is built-in that's why we don't recommend modifying the laptop.
