Wifi (WPA) extremely unstable (on and off every 5 seconds)

I have had an Arch install on my laptop for a while, but haven't been using it.  I just decided to get it functional again, but I can't get my wireless to work properly. I am using a WPA encrypted router and therefore using wpa_supplicant to connect to it.  The router is the only thing that changed between when it was working and now (both routers are WPA). 

I am running wpa_supplicant in a terminal to see when it disconnects and what it is doing.  I can only stay connected for between 5 to 20 seconds before it disconnects.  It will then attempt to reconnect right away, sometimes failing, but usually succeeding.

I tried using netctl instead, but the results are exactly the same. When it disconnects it usually does this:

wlp4s0: CTRL-EVENT-DISCONNECTED bssid=00:24:36:ad:1e:c5 reason=4 locally_generated=1
wlp4s0: SME: Trying to authenticate with 00:24:36:ad:1e:c5 (SSID='Home Network' freq=2432 MHz)
wlp4s0: Trying to associate with 00:24:36:ad:1e:c5 (SSID='Home Network' freq=2432 MHz)
wlp4s0: Associated with 00:24:36:ad:1e:c5
wlp4s0: WPA: Key negotiation completed with 00:24:36:ad:1e:c5 [PTK=CCMP GTK=TKIP]
wlp4s0: CTRL-EVENT-CONNECTED - Connection to 00:24:36:ad:1e:c5 completed [id=0 id_str=] 

But sometimes authentication fails. 

Any help is appreciated.

Edit: I should say this is the card i have:
04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter
