How do I upgrade my Sony VAIO to support Wifi AC network? This is horrible that my 2 to 3 year laptop doesn't support AC network. In my home I have a 5 year old IBM X200 laptop which natively supports AC, my Dell allowed me to upgrade to support AC without any hitch, Dell being from 2010 era. However Sony which I bought in 2014 doesn't seem to support and based on what I read in this forum - may not even allow the upgrade! Can someone please advice?
My OS: 64-bit Windows 10.
Any Sony bloatware present: None. Removed EVERYTHING
HDD: Samsung SSD, 850 EVO 256 Gb.
