Wifi is 4x slower on Arch than it is on Windows with Asus pce-ac51

I recently installed an Asus pce-ac51 wireless card in my desktop. I installed the manufacturer driver on Windows and was getting upwards of 100Mb/s on speedtest.net. On linux, I am getting less than 25Mb/s. Is there any way to get the speed up to what it is on windows. I tried to install the driver that Asus provides for linux, but I was getting a make error. The driver that I currenly have installed is rtl8821ae.
Here is my lshw -C network output:

  *-network

Here is the error I get from when I run the install.sh file from the included Asus driver

Re: Wifi is 4x slower on Arch than it is on Windows with Asus pce-ac51

That driver package is 2 years old ...

Did you try
a) the mainline kernel (rather than the lts one)
b) disabling power saving by passing

ips=0 aspm=0 swlps=0 fwlps=0

to the rtl8821ae module?
