Topic: Update on Linksys WRT1900AC support

10 Jan 2015, 07:40

@DavidMcWRT

Fantastic post. Thanks for summarizing it. Although it was directed to Rick, is certainly helps other people seeking for information.

Perhaps most of the information that you've put there can be used to update the Wiki and help other people that are looking exclusively there for updates about this device.

Best regards,

FREDY

Hi Rick,
I'm writing this in a positive way.
From your posts I can see:
1) You bought a WRT1900AC in early June 2014. You're running stock firmware and haven't had any wireless issues with it.
2) You're waiting for a stable open source release.
Unfortunately Linksys/Belkin/Marvell messed up, as documented through the first 30 pages of this thread. To summarise, they didn't consult with the OpenWRT community before announcing the product and that OpenWRT would be available for it. They then dumped OpenWRT builds onto us that (a) used binary blobs, and (b) used hacked up code that couldn't be incorporated into OpenWRT as it was.

As far as I can tell, right now it's the *only* consumer 802.11ac router that's working with mainline OpenWRT, partly because almost everything else is using a Broadcom chipset.

What about the TP-Link Archer C5 and C7v2?
http://wiki.openwrt.org/toh/tp-link/tl-wdr7500

I was under the impression it works. But I don't have one myself so I only believe what I read on this forum and on the OpenWRT wiki.

I have told other people the Archer works - I don't want to give people the wrong information.
And other people may be reading this thread and get the impression that the Archer does not exist, and that would be unfortunate if it happens to be the right router for their needs.

Anyone who wants to clarify?

That said, it is so great to read about the progress of the WRT1900AC! I might get one just to join the fun!

10 Jan 2015, 11:09

The C7v2 works (including 802.11ac), although it seems from various reports that the ath10k driver isn't quite perfect.

Just remember /tmp is in RAM and gets cleared every reboot. So don't stick anything in there you want to keep between reboots...

I'm interested in what, if any, compiler options (CFLAGS) are set for speed/size.
I don't know anything about the buildbot system, but my hunch is that it's just a cross-compiler setup.
It may therefore not specifically set a
-march=archname
CFLAG to use CPU instructions specifically for the one in the WRT1900AC. /proc/cpuinfo gives that as "ARMv7 Processor rev 2 (v7l)", but I can't cross reference that to any of the particular armv7 names GCC supports (armv7, armv7-a, armv7-r, armv7-m, armv7e-m, armv7ve).
Also, whether any code optimisation level is set. I guess we'd want -Os to optimise for performance and size; else if size isn't an issue we could go for -O3 to for (in general) the fastest code.
According to http://downloads.openwrt.org/snapshots/ … bu/config,
CONFIG_DEFAULT_TARGET_OPTIMIZATION="-Os -pipe -march=armv7-a -mtune=cortex-a9 -mfpu=vfpv3-d16"

Thank you

Clearly the group here ARE working very diligently trying to push the limits forward AFTER Marvel decided NOT to release the driver source code.
There is WAY TOO MUCH crap software in the market place; due to individuals AND companies that don't understand QUALITY.
When I worked in the medical electronics industry as late as the early 2000's; it was common knowledge that for every hour of programming it required 10 hours of testing.
Today for every hour of programming; software is lucky if it gets 5 minutes of testing; and WE wonder why software mostly does NOT WORK. Microsoft, Apple etc. are at the top of the list!
RickStep
I really don't like to make these kinds of posts, but I think I speak for a few members here, if not I will stand on my own. If you are having trouble with forum software, sorry. It is working for the greater percentage of us. In case you don't understand open source, it is just that open free for people to change, modify, play with, and do what ever their hearts desires with it. And most if not all of the developers here are doing it free and sharing it with the rest of us. That is awesome!!!! Thank you to all of you for sharing your talents. So most of what you see is donated and some of it is free as maybe this forum, I am not sure. So quit complaining about the forum software, and please quit posting the crap messages.
I personally resent your threats of breaking fingers of commercial programmers, some of us on here are that commercial programmers. I am one of those commercial programmers, I learned to program in assembly language and FORTRAN, back when memory/hard disk was a premium and your code had to fit into a very tiny little space. But I could a lot with both of those languages together, I could control printers, plotters and do some wonderful things with them. I enjoyed playing with registers and such..... Ah the memories.... But I digress off my point. My point is, every since your first post you have done nothing but complain and grip, and now you are demanding that software be repaired on a site that is being used. You indicated your programming skills is in windows, well this is windows... Why don't you fix it.
My final comment, if you are not going help by reporting errors, testing, or just be a sideline cheerleader to see this grow, mature and become a workable solution and you just want to spew complaints, please quit posting. Open source is not the place for you. I just know I am tired of hearing your complaints/crap such.
Later,

Software is the most difficult to test and debug.

Our school systems have primary grade pupils and secondary grade students writing programs. Do they work; YES. Do they follow any standard; NO. If posted online for others to use securely; NO.

The grade school pupils & higher grade students can't use carpentry tools, can't cook, can't fix a car, can't design an electronic circuit; BUT THE SCHOOL SYSTEM has taught them the are SOFTWARE PROGRAMMERS.

The problem is; IF some of these "kids"; many of these kids that get a university degree in software engineering; HOW do you break them of really bad programming habits.

Most "kids" that learn to program in public school systems like it so much that they produce programs today (aps) for smartphones & tables etc. and despite their university degree NEVER get away from CRAP programming.

It is way easier to teach someone how to program from scratch; than it is to BREAK programmers from OLD HABITS.

I was not taking a swipe at a dedicated group here; bat at the programmer/group that sold the software that allows these posts.

The "board" software IS crap!

My bank logs me out after 15 minutes of inactivity. Lots of other sites also do in more or less graceful ways. There are good reasons to not let sessions live forever. Perhaps something got restarted and your session ended prematurely. Get over it. The forum works for its purpose, and someone keeps it alive for us who don't pay a cent for it.

Prior to that post of mine you had been the only one to experience the issue. My post confirmed it also happened to me. It seems it's a "corner case" though; I only triggered it when I took the time writing a very long post.

The software used for the forum appears to be PunBB. I'm sure the authors are just as "dedicated" as we are with their own software.

It's also GPL, so the source code is available:
http://punbb.informer.com/downloads.php
should anyone have the time or skills to track this problem down.

In any case there's also a bug report page:
http://punbb.informer.com/bugreport.php
and I have reported the bug to them.

I really think there is a hardware problem with some of these routers and despite all the good work here; programmers are re-proofing their work chasing software problems that are actually hardware problems with the WiFi transmitters on some units and re-writing the firmware will never fix some routers.

I can't fix this. I offered only to tableize the data once a week. I also asked if there was a utility run under windows that could read the data from a router using firmware written in UNIX and its derivative Linux .

If I can be helpful, I can help collect the data.

If none of the programmers believe that that some routers may have defective hardware; I will do nothing.

It was and is a simple question.

For what ever reason the SWIPE at the board software took over AND the board software is still broken. This board is NOT A BANK!

Or better say, some apple products, and it seems the issue is with the OS X / IOS wireless stack. As other reported no issues with iPads, I guess it's even IOS version dependent.. Also, even I do have issues if I boot my MBA to OS X, and it's flawless with Linux.

All software has bugs. Thanks to you we know about this one. You and I are the only two who have ever been affected by it.

There's a work-around: copy and paste the message into a separate (text editor/word processor) window before you hit submit, then if you do have a problem you at least won't need to type the post from scratch again.

It's actually something I tend to do when submitting email enquiry web forms because quite often it times out or the captcha's wrong or I need to correct a field or something.

I've submitted a bug report and we have a work-around.

You are implying that somehow the vendor firmware is specifically written to work around these hardware bugs.
That's probably not the case.
