I ran to the same problem a lot of people have. I wanted to upgrade my y500 wlan card in order to conect to 5GHz bands. I found two solutions on the table, one risky the other one not so much. The first one consists in removing the BIOS whitelist and the second one is about flashing the actual card (what I find really troubling). What do you guys think? Have you tried any of these methods?
