better router software, that just works, with videoconferencing, IPv6<br>
support, and OTA functionality. No need for a truck roll, and while<br>
the available bandwidth deep in these mountains in Mexico is meager,<br>
it is now enough for most purposes.<br>

I have no idea how many of this model routers were sold or are still<br>
deployed (?), but the modest up front cost of this sort of development<br>
dwarves that of deployment. Ongoing maintenance is a problem, but at<br>
least they are in a position now to rapidly respond to CVEs and other<br>
problems when they happen, having "seized control of the methods of<br>
computation" again.<br>
<br>
OpenWrt is known to run on 1700 different models, already, (with easy<br>
ports to obscure ones like this box) - going back over a decade in<br>
some cases.<br>
<br>
Another favorite story of mine was the ISP in New Zealand that<br>
deployed LibreQos and had all their support calls (from gamers and<br>
videoconferencers) cease overnight. The support tech, formerly drowned<br>
in angst from the users, set to work automating an reflashing 600 old<br>
agw routers they had "retired" on the shelf, and then distributing<br>
them to customers as extenders because the wifi finally worked right<br>
with the fq_codel stuff now in that release.<br>
<br>
I feel like I am tooting my own horn here a bit too much, but solving<br>
the right problems like MTTR, MTBF, bufferbloat, and taking back<br>
control of your software infrastructure while being able to customize<br>
it for purpose, and turning what otherwise would be ewaste into<br>
something that will last a decade more, is my inner "green", my inner<br>
stewart brand.<br>
<br>
Compare that to so many others being marketed to, to death, that buy<br>
the latest (and often inferior) thing, every few months, perpetually<br>
fooled by promises that do not pay off in the field, and often, really<br>
lousy MTBF. Good embedded software takes many years to develop, say,<br>
oh, 7, while the hardware cycle is closer to 2, nowadays, and requires<br>
many eyeballs to fully debug and get to lots of 9s of reliability.<br>
<br>
Back when I was even more radical about good, open, embedded, software<br>
than now, I used to say: "Friends don't let friends run factory<br>
firmware.". I do wish somehow the long term maintence costs of<br>
hardware with a decade plus service lifetime would be adaquately<br>
covered. Insurance? by law? a formal setaside from the purchase price?<br>
Otherwise we run the risk of turning the world's internet into a giant<br>
toxic waste dump that will require Superfund levels of cleanup, one<br>
day, and ever more contributions to trillions of dollars of fraud, and<br>
persistent actors having first broken down the front door, perpetually<br>
on the inside, wreaking more havoc. Somehow preventing that mess, up<br>
front, seems cheaper.<br>
<br>
Take this string of vulns:<br>
<a href="https://www.google.com/search?q=cisco+router+vulnerability" rel="noreferrer" target="_blank">https://www.google.com/search?q=cisco+router+vulnerability</a><br>
<br>
(try that search string with *any* manufacturer - juniper, netgear, tplink,<br>
<br>
There is a new vuln going around about some very old software in a<br>
cisco mx series which is ancient and yet 100k+ are vulnerable - (I<br>
worked on this while at montavista in the early 00s!) - abandonware,<br>
toxic waste...<br>
<br>
Anyway, in Mexico at least, 200+ routers are going to be a lot better,<br>
through the actions of all that contribute to linux, openwrt, and one<br>
smart and caring engineer.<br>
