So this is two computers talking to each other over WiFi? What
chipsets/drivers are they using for WiFi? It may very well be that what
you're seeing is hickups in the WiFi connection at the computer, not at
the router. In which case there's nothing you can do on the router to
fix it.

Another possibility is that it's an occasional signal drop that causes
excessive retries (either at the router or the AP). We have not gotten
around to limiting the retries in the drivers yet, so that can cause
quite a bit of very intermittent head of line blocking as well.
