We understand that you would like to replace the wireless adapter in your Vaio laptop with the Intel® Dual Band Wireless-AC 7265 or other suitable one. We would like to mention that the Intel® Dual Band Wireless-AC 7265 is only available in the new M.2 form factor; and the older Intel® Dual Band Wireless-AC 7260 was the last adapter from Intel to be available in PCIe Half Mini Card (HMC) form factor. You might want to check with Vaio if your PC is compatible one of these adapters, or any other one of the current Intel® Wireless Products.
Please keep in mind that Intel does not support, nor recommends custom integration of wireless adapters since this may lead to installation errors, connection issues, software error messages, and in some cases it may even be illegal.
Intel does not recommend end users install or upgrade the various Intel® Wireless Adapter; you should always contact the Computer Manufacturer Support or its authorized representative to check which adapters are supported by your PC and have replaced with them whenever possible.
