hey folks,
made a troubleshooting section on the walkthrough, please add other cases
of issues and how you resolved them!
Just got this n600 flashed that had had the rest button fall off. Back on
there and working fine now.

Would love to put together some proposals for AMC next year!

To: Dev Summit Discussion <devsummit(a)lists.aspirationtech.org>
Hi friends,
Call for Proposals is open for Allied Media Conference 2020.
I can't say enough nice things about what a great event this is, and
2020 will be a unique year, as they took a year off to recharge and
rethink everything about the event.
The proposal info is here:

>From what I understand, Western Digital has dropped their line of My Net
products, and instead is supporting My Cloud devices. Those will be really
fun to hack on later on as they get old and cheap (especially for
distributed networking projects, no?) WD has already stopped offering
support for the My Net products and have definitely stopped selling them.
So eventually we will also run out of n600 and n750 stock. Plus, the price
has gone up to near-MSRP for the n750:

Following the suggestion from Guifi.net visitors years ago -- to build our
network to provide a good service experience, we should use new hardware
(when we can) to get performance boosts from improvements to radio,
power-management, and standards technologies. It seems like we may want to
find the next router to support, and I'm curious what folks have looked at
lately!
It seems the search may be for affordable, good quality,
dual-band/dual-radio routers that are openwrt-compatible. Plus, devices
that support new technologies like 802.11ac (Wave 2?) and 10/100/1000 MBPS
wan/lan ports (more easily take advantage of fiber services from Sonic.net
/ Cruzio / etc). Interestingly, we may also find affordable options from
brands like MikroTik that seem to have more US distribution than before if
I recall correctly.
Here's my short list from quick research, lmk what you think:
- Netgear R6220
https://www.netgear.com/home/products/networking/wifi-routers/R6220.aspx
- TP-Link Archer C7
https://www.tp-link.com/us/home-networking/wifi-router/archer-c7/
- MikroTik hAP ac lite https://mikrotik.com/product/RB952Ui-5ac2nD
Mesh-folks,
I have flashed the WD N600 router twice, and it fails to connect to the
mesh. As far I was able to tell, the second time it connected, but after 1+
hour the fun ended.
LOGS:

it a DNS issue on the exit node end?

Hi there folks,
After years of learning a bunch of stuff off of mailing lists I've
started working on using them. I want the messages I send to last and
be referred to later on, so here's a random reply in a mailing list.
For cheap hardware there are many great opportunities with
end-of-life'd enteprise stuff. Brands like Meraki and Aruba require a
license to run, which often means that large lots of hardware suddenly
become useless to the original purchaser and are sold for less than a
penny on the original dollar. When you combine this with the fact that
a lot of ath10k and ath11k hardware has usability issues, the
advantages of sticking with slightly older hardware become obvious.
I have been stockpiling lots of Meraki MR16, MR18 and MR24. Was able
to purchase about 250 MR16 for about $700, and trivial quantities of
the latter for about $6 and $10 apiece for testing. All hardware has
gigabit PoE (active or passive); the MR16 has 2x2 an and 2x2 bgn
(AR9220, AR9223); the MR18 has 2 x 2x2 abgn (AR9582) and one 2x2 bgn
out of the SoC, and the MR24 has 3x3 an and 3x3 bgn -- notably using
mini PCIe slots rather than integrating them into the board, see board
images here:
http://en.techinfodepot.shoutwiki.com/wiki/Cisco_Meraki_MR24
My suspicion is that the MR24's PCIe slots can be used with pretty
much any mini PCIe cards (as long as they don't require the USB-side
of the slot). This means we can stick, for example, Compex WLE900VX in
them -- 3x3 abgn/ac cards with decent power and laughable
affordability ($20/pc in single quantities). These run ath10k and are
known to be OK to run in VHT-IBSS - after all the Archer C7 uses these.
Flashing with OpenWrt is doable for all of these regardless of
firmware revision; riptidewave93 has done most of the work porting
these to OpenWrt. They have serial headers already on them, so for the
MR16 you just pop it open and plug in and power it up (I wrote a
script to automate it here:
https://github.com/btvmeshnet/hardware/tree/master/platforms/Meraki/MR16/fl…)
-- for the others you have to rebuild uBoot and reflash using a flash
clip ... but my point really is, these routers can be obtained in
bulk, have PoE so they can go anywhere, and have ath9k-based hardware
so "just work with mesh no matter how you want to use them".
Here's a lighting talk as done by Yurko of Tomesh:
https://ournetworks.ca/livestream/?m3u8=live-2019-09-22.m3u8&from=QmWyL7hcu…
I have a modification for the MR16 so that they can use external
antennas - it's quite simple, just drill two holes for U.FL-to-RP-SMA
pigtails in the two bottom corners and then screw in two pigtails from
the inside. The internal U.FL connectors are attached to both the 2.4
and 5GHz chains (this is why the internal radios cannot be used on the
same frequency). At that point, you just attach two external dual-band
antennas (or whatever else you want to stick on them).
I am happy to write up much more complete guides for all of these
things (I encourage EVERYONE to link whatever they write up into
techinfodepot, as it is where many people who get into hardware go and
learn). I am happy to flash and box up and ship 10 x MR16 + 5 x
gigabit PoE injectors + 1 x USB-to-TTL cable if you folks can make use
of them. I am happy to send folks TTL cables for free if they need
them (you can also do this work with any Raspberry Pi). Quite frankly,
to put them all to good use I would be happy spending all of my free
time buying, modifying and shipping these out in exchange for my parts
and labor cost (probably $8-$10 per MR16); my goal is to erase all
barriers to reusing this hardware, as it is cheaper than dirt, tougher
than nails, and is PoE-capable out of the box.
I also see many more opportunities out there - like RTL8812AU (see
aircrack-ng's repository for the driver) for
very-high-throughput-point-to-point at low cost. I really would like
to improve community knowledge of hardware so that those who have the
most time and the least funds can gain and share knowledge of these
things, which should (in theory) continue to improve access to
hardware for everyone (because there are more interesting problems to
solve than hardware).
Sorry if this email is exhaustive. I don't see any good single place
to collaborate on this so I'm doing a bit of a thought dump. Would be
very happy if I found a good way to link together communities better
as it took me years to do all this info discovery (did not know
Sudoroom had a mesh mailing list until now).
For hardware information in general I have been hoping to have
consolidation, but since wikidevi.com has come down and is being
migrated to techinfodepot, the new place for hardware info is here:
http://en.techinfodepot.shoutwiki.com/wiki/Main_Page
Let me know if you can use the box of Merakis; happy to send at no cost
if I have a destination.

Calling all Alameda folks...
Anybody interested in creating a wireless link to San Francisco?
We have somebody with really good line-of-site from Bernal Heights that wants to create a link
to the East Bay.

Sudomesh node 20 (MAC: 0090A90C76E0) will be going offline indefinitely on 1 December 2019.
I would like to return nodes 20 (currently online) and 6 (currently offline, acting as a spare) to Sudo Room for redeployment.

hey all,
I recently flashed a node, so I updated the walkthrough to hopefully be
easier for others to follow, please review!

Hey all,
I was just visiting a friend in SC who had a node from this net in their
place. Is it using the exact same firmware, configuration, and
documentation as sudo mesh is using for peoplesopen.net?
If so, want to verify that devices flashed DIY and configured automatically
will be inter-operable. If not, I am interested in creating a bridge
between the networks or devices.
