What does "latest firmware" mean? Which firmware? dd-wrt? Asus' own?
I'm assuming Asus, as he said it was originally stock. Bufferbloat happens where a slower link meets a faster one, and the symptoms are indeed insane latency when doing anything that has to pass through the same buffer as a bulk transfer. Any the XX-WRT router OSs will have a recent fq_codel, and the team (Dave Taht, and fiends) are working on similar problems in wi-fi. If the Asus router says it has fq_codel, check and see if you can move the bulk transfer to a wired interface. Ditto if you use DD-WRT and friends. Wi-fi is sorta "fe-fi-fo-fum, I smell the bloat of a bufferman" (;-)) --dave -- David Collier-Brown, | Always do right.
