I've just started using wireless again after being on wired for a long time and I am having some severe ping troubles.
Previous to being on wired and using wireless I had no issues but now COMING back to it something is wrong.

Issue:
Ping SPIKES of over 1000ms to my router at random intervals

Pinging to my router:

Attempted Solutions:
REINSTALLED Drivers
Trying different Wifi settings
Switching between 2 and 5 GHz bands
Factory Resetting Router
Installing WLAN Optimizer
Disconnecting all other wireless devices from the network
Virus/Malware scan

So far none of the above have worked

OS: Windows 8.1 64 Bit
My NIC is as http://www.asus.com/uk/Networking/PCEAC68/ , I spent a lot of money on it to make sure I would have no wireless issues but apparently that is not the case.

Although the average ping is higher I don't actually get these incredible spikes on my phone which leads me to BELIEVE it's on my computer's end.

Any help would be appreciatedI have just tried using a connection analyser to see if anything was HAPPENING network-wise on my PC during the spikes but there was nothing noticeable at all. I am extremely lost on this one.
