[Cerowrt-devel] failing to find the declared victory in a current wifi router

2015-07-06 Thread Joe Touch
Hi, all,

I'm posting because of my recent frustration with the claim that
bufferbloat solutions have been pushed up into the OpenWRT and
commercial routers.

I spent the bulk of last weekend trying to find a COTS WIFI router that
supported OpenWRT with bufferbloat (SQM) extensions.

I tried a Linksys WRT1200AC, and here's what I found:

- Kaloz's 23-Apr-2015 build installs fine and comes up
with a web server (LUCI), but does NOT include SQM

- trying to install the SQM packages fails
due to a kernel version incompatibility
(for a 23-Apr-2015 build?!)

- CC-rc2 doesn't have a WRT1200AC build
presumably I should have used mvebu-armada-385-linksys-caiman,
but it's not at all clear

- and I'd have to install LUCI and/or reinstall
factory firmware from the command line, and none
of that is all that clear, esp. a recovery route
that doesn't involve voiding warranty to wire in
a serial port

Given the declared victory (http://www.bufferbloat.net/news/53),
perhaps someone one one of these lists can explain why there's no clear
information on a current device that supports a current build that
actually supports these fixes?

I.e., if you were trying to make this obscure, you're doing a very good job.

FWIW.

Joe

Re: [Cerowrt-devel] wrt1900ac v1 vs v2

2015-07-06 Thread Rich Brown
There is an active discussion of the WRT1900AC routers at the OpenWrt forum. 
That would be a very good place to ask this question.

 So what are the differences between wrt1900ac v1 and v2?  Is there any reason 
 to pay nearly $100 more for a v2?

It looks like the 1900v2 and the 1200 have the same chipset, i saw that the 
1900v2 got more memory and a faster cpu to bring it up to match the 1200.


My understanding is that the only difference between the two is 2x2 vs 3x3 and 
the cost.

Having not bought a 1200ac yet, I was wondering if I should splurge for the 
1900ac v2 (which has lots of memory unlike the 1900ac v1).

Any thoughts on the compatibility of this with the 1200ac?

Current plans are to deploy Supermicro Mini ITX A1SRI-2558F-O Quad Core (Rangely) as my 
externally facing router and services platform, and either one of the above 
as my experimental wireless solution.

 Do you have a link to your .config for your builds somewhere?

Cool, thanks!

 BUT! I have had problems getting WPA2 to work properly with this
 .config. I must have missed something that is needed that has to do
 with the password/crypto handling.

 There already is a profile for the WRT1200AC (caiman) in Chaos Calmer
 RC and trunk, so it's actually not that hard to get working. The
 biggest problem is finding all those utilities one wants and making
 sure they're compiled into the image so one doesn't have to add them
 later.

Yeah, realise that. Still have my old .config from when I used to build
cerowrt for the WNDR lying around somewhere, so will take a look at
that and make sure everything is in there :)

Hi, Rich,

 Hi Joe,
 
 The OpenWrt firmware project is a some assembly required affair. 

That might be less daunting if there were assembly instructions. I.e.,
I'm suggesting that the instructions need revision. Work there could
have a significant payoff in a larger test community (I'm not exactly a
hardware noob, but I found it annoyingly obfuscated).

 Although it's not always easy to find, the site has a number of resources:
   - Buyer's Guide at http://wiki.openwrt.org/toh/buyerguide

That is useful for picking from among the currently supported versions,
but perhaps it'd be useful to take a colleague with you to a store and
see how helpful that all is. It's nearly impossible to find any of the
devices in the list or to verify whether a particular device in a box
has the required version of motherboard and firmware needed.

   - The specific guidance to search Amazon for OpenWrt - see: 
 http://amzn.to/1mONYr0

That turns up quite a bit of devices that aren't supported, FWIW.

   - The forum at: https://forum.openwrt.org/viewforum.php?id=10 mentions 
 lots of routers

Indeed; more isn't better.

 As for specific routers:
 - The WNDR3800 remains our gold standard for CeroWrt builds. It'll
 do SQM up to ~30 mbps, then the CPU runs out of gas.

May I also suggest moving to another standard that hasn't been
explicitly end-of-life'd by the manufacturer.

 - Check the OpenWrt Table of Hardware (ToH) to see what other routers
 support the current stable 14.07/Barrier Breaker (BB) builds.

Sure - I spent several days in Target, Best Buy, and Fry's trying to
decipher whether particular products were supported - again often
difficult without UPC numbers (boxes don't always indicate version)

 - Many people on this list have good luck with the TP-Link Archer C7
 v2. I believe it'll route at cable speeds. I'm using it very
 successfully with OpenWrt BB release on a 7 mbps DSL line.

Here's a good example of how useful the information on the OpenWRT
website can be. Everyone seems to refer to this as Archer C7, everyone
except the TP-Link website. Their search finds no products matching that
description, and the WIFI routers there are listed with other codes,
e.g.:TL-WDR7500 - except you won't find that number on the hardware page
-- you have to click through to the page for that device.

For that device, like for many, the most recent version (i.e., the one
more likely to arrive on a blind web order, or on most store shelves) is
not yet supported.

 - If you have been following the Linksys WRT1900AC and WRT1200AC 
 thread at
 https://forum.openwrt.org/viewtopic.php?id=50173action=newyou'll see
 that the CC builds are sorta, kinda working. There are a lot of moving
 pieces still, and despite the CC RC2 status, stable builds only come
 out a few days apart. I would stay away from it if you're not willing
 to participate in a science experiment.

Well, the 23-Apr-2015 build by Kaloz works fine - except that the SQM
package fails to install.

What I'm baffled by here is that the main trunk builds leave LUCI out;
that's seems
quite short-sighted, IMO.

 There is a team working to improve the OpenWrt site, but our work
 has not yet been blessed by the the admin's who maintain the core pages of
 the site.

And I appreciate and understand that. The CeroWRT site could similarly
use an update.

I.e., there's ample opportunity here to build a larger community with a
few simple steps:

- refer to routers by the manufacturer's designation
- create builds with both LUCI and (if possible) SQM
- make a short-list of a few currently available routers
for which an integrated build exists *for the most recent
motherboard version*

All of this could be done on the CeroWRT site until it can be put on
OpenWRT.

These are fairly direct ways to lower the bar, which seems unnecessarily
high here.

Joe

 Best,
