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.
sure possible, can't say it's not, I did manage to find a channel that only I'm on in the 5 ghz range and all machines are within 2 meters of the AP. But of course it's wifi so, no real guarantees.
Both computers are running windows 10. Server is running a qualcomm device says it's using the killer wireless n/a/c version 4.0.2.26 (fishy, I know killer wireless is sort of it's own qos, I think I've effectively disabled it though). Client is running an Intel Dual Band wireless AC 8260, driver 19.71.1.1.
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.
could also be, do those retries happen when it's udp? 'cause I think steam homestreaming is basically all udp, maybe the packets are just getting dropped?
