I've just started using wireless again after being on wired for about 3 months and I am having some severe ping troubles. As far as I'm aware nothing in my computer has significantly changed that could affect my wireless connection.

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

Pinging to my router:

Attempted Solutions:

• Reinstalled Drivers
• Trying different Wifi settings (channel, wireless interface type)
• Switching between 2 and 5 GHz bands
• Factory Resetting Router
• Installing WLAN Optimizer
• Disconnecting all other wireless devices from the network
• Virus/Malware scan
• Using older drivers
• Disabling a number of process and services and preventing them from starting up
• Booting in Safe mode

So far none of the above have worked

OS: Windows 8.1 64 Bit

My NIC is an 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.

This is not occurring on any other wireless device I use with this router which leads me to believe something on my PC is causing it.

Any help would be appreciated
