I'm back with new custom builds, for our little friends; the most common TP-LINK with 4MB of flash memory.

First of all use Devuan ASCII / Debian Strech) as a linux environment to compile LEDE & libreCMC (fork Openwrt https://librecmc.org/). I only use the official guide published in OpenWrt

Within the forum one or another user (somewhat paranoid of privacy) care about custom or optimized constructions.
You can check my .bin files by doing a quick reverse engineering using the following guide

Tested on my TP-LINK WR940N v5

@Dratas
If your router model appears in the list, you can occupy one of my custom builds otherwise you can leave your router like a brick

Dratas · July 28, 2019, 10:05pm

nope mine router is not in list,so i have option stay with regular LEDE Reboot 17.01.6 r3979-2252731af4 / LuCI lede-17.01 branch (git-18.201.27126-7bf0367) or go with OpenWrt v18.06.4

Hi! Thanks for all @xhaka , one question: This new version supports no-ip DDNS?

Edit: Can you summarize the advantages from using LEDE or libreCMC ? Should I choose one of them for something in particular?

xhaka · July 29, 2019, 1:32am

@lcfx
Hi,
These versions are lightweight, only includes Zram-Swap and SQM Scripts (check the changes section). I will not compile more complete versions at the moment.

xhaka · July 29, 2019, 1:34am

@Dratas You can now flash your router WR843ND v1, I just added it in the LEDE downloads

Dratas · July 29, 2019, 10:53am

@xhaka that name in first screen is changeable?that one in top corner "xhaka"or its like © sign of your?

xhaka · August 4, 2019, 5:06pm

Yes, you can choose the name you want for your hostname, in the section Sistem> Hostname

xhaka, thanks so much for the builds.

I have an old WR740N v1 that I want to use as a wifi network card for a smarTV that has a really bad wifi reception - anything other than the TV has no issues with the wifi.
To be able to use the WR740N in client mode, do I need do download libreCMC version with luci-proto-relay or LEDE v17.01.7 will do it?

thanks!

Dratas · August 10, 2019, 9:13pm

no libreCMC for tiny router?

xhaka · August 10, 2019, 9:47pm

For bridge support, use libreCMC for the luci-proto-relay protocol that was included in the compilation

xhaka · August 10, 2019, 9:47pm

Nop only LEDE 17.0.1.7 for WR843ND v1

Dratas · August 10, 2019, 11:57pm

then not much options i have.

Dratas · August 11, 2019, 9:27pm

@xhaka Question to this topic autor,there is no plans make custom build based on OpenWRT 18 but with all these small optimisations like did with LEDE 17.01.7 ?

xhaka · August 11, 2019, 9:51pm

I have not used OpenWrt in its branch 18.06 since last year since the new improvements is = more space, they leave the old 4Mb routers almost forgotten just with the possibility of using them in a generic way without being able to add some necessary package for the user. It has already been seen with Gargoyle or Pulpstone developers (LEDE / OpenWrt fork) that have updated to OpenWrt branch 18.06 have stopped supporting routers with 4Mb flash memory.

pedrohsk1 · August 22, 2019, 7:19pm

@xhaka does this version 17.01.7 perform better than 17.01.6 and 17.01.5? I am using a version that you made 17.01.5 with zram and works well with SQM, if I download this 17.01.7 would it improve more?

pedrohsk1 · August 22, 2019, 7:23pm

@xhaka, @xhaka, another question, is LibreCMC lighter than Openwrt in this version of yours? My focus is performance with SQM.

pedrohsk1 · August 24, 2019, 8:07am

It didn't work for me. Brazil, ADSL. It looks like you need ipv6, but it is curious that there is a version of you without ipv6 with zram swap that works well with me. Will understand ... If you can build in the future just like this but with ipv6 support, please post here. Thankful.

xhaka · September 29, 2019, 9:59pm

@pedrohsk1
My custom builds are designed to be used in secondary or neutral routers, if you want ipv6 an SQM, etc. it is recommended that you use a main router with at least 8Mb + Flash memory.
Forks derived from OpenWrt such as Gargoyle and Pulpstone, have stopped supporting routers with 4Mb of flash; It's time to upgrade to new technologies
