I get awful pings spikes on both wireless and wifi connections. Ping spikes are not common when idle but ramp up when playing online games or streaming.
I have tried:
-Changing wifi adapters
-Changing wifi channels
-Running multiple virus scans
-Running in safe mode with networking
-Trying a wired connection
