you could be pinging your router, or google
is the router ping latency OK?

I would personally fire up wireshark and see what traffic is going in and out of your machine if you think that that's the only device experiencing any problems.

Alternatively, install Linux.

I just updated the firmware on the router.
It seems to be ok. Fingers Crossed.
