Hmm..that would indicate a wireless issue. However, just restart your PC in Safe Mode with Networking, then ping and see if you still get spikes.
Is your Wirless network secured (WEP, WPA?)? If so, try disabling it then ping to your router from the PC- do you still get the spikes?
Also, you havent still told me whether the spikes occur at regular intervals or randomly.
