Would it be possible for you to test the older firmware on Trusty(14.04)? This can be done by copying the firmware file from a 13.04 install to the 14.04 install. The file can be found at: /lib/firmware/rtlwifi/rtl8712u.bin

The first time you boot into the system after installing it, it works fine. However, after you install your usual programs like Steam, Skype, smplayer, etc. and reboot the system will fail on such a grand catastrophic scale that you can't even boot into recovery mode since that will begin spamming error messages quickly as well. It isn't related to the kernel because I used the same kernel in Ubuntu 13.04. I also had the same problems with Ubuntu 13.10 (I'm not sure if that still applies but I will soon find out). Meanwhile, Ubuntu 13.04 with kernel 3.12 works perfectly.
