Well since I reported this bug I have found out that the linux-firmware from http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb solved my and my sons 5GHz issue.
I ran these two commands: wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb sudo dpkg -i linux-firmware_1.158_all.deb
As I stated in the forum "http://ubuntuforums.org/showthread.php?t=2325359&page=2"
After that the wireless card has been working as it should.
