Do you use a Belkin router, I have an N+ and there are numerous complaints about disconnects and random periods of major lag. I updated the firmware and flushed DNS and release/renewed the WAN IP, now I'm running pretty smoothly. I figured out it was the router when using google talk to talk to my wife in the states, it would drop speech ability but not the connection entirely for about 3-5 secs, something like 1 or 2 times every 15min.
