+ actually tested for an hour so far on 5.4ghz, with a us countrycode
and wpa+psk enabled...
Get it at:
http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.36-1/
but: there isn't much other reason to upgrade to this...
- no progress on the wifi bug - but I am beating up wifi with a variety of
devices and scripts today hoping to make it fail, and bringing up a
bunch more tomorrow.
- toke's script relies on stratum '16' changing, and it doesn't with openwrt's
ntp, it seems....

Here are some betterspeedtest.sh results for 3.10.36-1:

I think we are establishing that you can set downloads to above the
measured value at above 22mbit. Please try again with download 60000,
and pick another number for uploads higher than 80%.

That's pretty lame compared to your ipv4 results, but the length of
the path looks the same... puzzling... How much further (or less far)
is rich's box (traceroute6 -n netperf6.richb-hanover.com) on ipv6 vs
ipv4 (traceroute -n )
I have certainly seen bottlenecks, excessive delay, and packet loss on
he's gateways.
An "mtr" might be revealing during the test for spotting packet loss
further on the path.

While mtr is at best an unreliable measurement, your data certainly
