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

Re: [Cerowrt-devel] wrt1900ac v1 vs v2
There is an active discussion of the WRT1900AC routers at the OpenWrt forum. That would be a very good place to ask this question. https://forum.openwrt.org/viewtopic.php?pid=282552#p282552 Best, Rich Brown On Jul 6, 2015, at 9:59 PM, John Yates j...@yates-sheets.org wrote: There are refurbished wrt1900ac units available quite cheap ($10 or $20 more than wrt1200ac).

Re: [Cerowrt-devel] performance numbers from WRT1200AC (Re: Latest build test - new sqm-scripts seem to work; cake overhead 40 didn't)
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.

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.

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 :) -Toke ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel

Hi, Rich, On 7/6/2015 7:23 PM, Rich Brown wrote: 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.
