I have a 4 year old Sony Vaio 16" laptop
I just did a clean install of windows 10, and all of a sudden i had 5 Ghz support.
Never had that with win 7.
I even e-maild Sony about the possibility to upgrade from 2.4 ghz to 5 ghz, if i could chande the network card or something.
Turns out, all i needed was windows 10.
WHAT?
how is this possible?
