I could try running wireshark on both, it's a ton of packets, and I'll be
honest, I don't know that *I* would know what to do with them.

steam homestreaming has an in game performance monitor, it shows you your
ping, estimated bandwidth, and how fast it's currently streaming. So when
the game stutters I also notice a recorded ping/latency increase. Sadly
though, it doesn't include highly detailed logs to my knowledge.

Yeah, those are link-layer retransmissions. The ath9k driver sometimes

that's fun...
