I have seen the same thing, although with different CeroWrt firmware. = Netalyzr was reporting > 500 msec buffering in both directions. However, I was simultaneously running a ping to Google during that = Netalyzr run, and the ping times started at ~55 msec before I started Netalyzr, and = occasionally they would bump up to 70 or 80 msec, but never the long times that Netzlyzr reported...

A couple thoughts: - There have been a bunch of changes between 3.10.13-2 and the current = version (3.10.24-5, which seems pretty stable). You might try upgrading. = (See the =93Rough Notes=94 at the bottom of = http://www.bufferbloat.net/projects/cerowrt/wiki/CeroWrt_310_Release_Notes= for the progression of changes). - Have you tried a more aggressive decrease to the link speeds on the = AQM page (say, 85% instead of 95%)? - Can we get more corroboration from the list about the behavior of = Netalyzer?
