HP pavilion g6-1207ev and new intel Wifi module = error 702

Hello everyone, i have an old Hp pavilion g6-1207ev which i upgraded (ssd+ram) and i also wanted to upgrade the wifi module from broadcom bcm94313hmgb to Intel ac 7260 .
Unfortunately i get the error 702 on startup (Wireless module not supported).
Does anyone have any suggestion? Is there a bios mod?
Or does anyone have another wifi module with 5ghz to suggest me?
Thank you
