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" (;-))
