Oh, cool. I had figured the actiontec router was a hard requirement.

Can you point us at a specific one?

Good information, thank you. I had no idea you could toss the supplied
router out the door in verizon's case. They are not doing a very good
job of maintaining the firmware.

Well, you are bottlenecked on the wireless side for speedtest. And netalyzr
can rarely achieve more than 20Mbit on anything. So some of your joy is

What I'd found from testing esr's verizon 25/25 connection was that only the
downlink needed some shaping. at 80/25 I imagine there's not a lot of
downlink buffering.

3.10.32-9 is in the "happens to be pretty stable" catagory, rather
than "intended to be stable". :/

We started shooting for a long-term stable build last august, I'd
hoped to have one by december, and then by mid-feburary...

We seem to be getting close! There are no priority 1 or 2 bugs left, churn
upstream is settling down as barrier breaker gets closer to a freeze, dnsmasq
w/dnssec is nearing a release.

Aside from a couple features I really wanted to have (bcp38, babeld in
procd), and a protocol I wanted to obsolete (ahcp replaced by hncp),
and a daemon I wanted to replace (mdns hybrid proxy in place of

... it is long past time to draw a line and declare it done enough.

I think the biggest thing left to do is push the SQM system upstream to openwrt
for comment and revision.

I'd like to gateway a "stable" cerowrt 3.10 on barrier breaker itself
going into a freeze, but can live without that.

AFTER there's a stable release...

There is a ton of new work to do (if I care to think about it) with
the new hnetd (hncp) stuff, the mdnsproxy, hardening the OS further,
getting source specific routing to work better with vpns, finding a
higher end platform with more oomph, etc, but we have to go looking
for grant money to do any of that.
