I heard that TP Link routers use OpenWrt in their stock firmware

Is this true? Any reference to support that?


Yeah. I just went there and downloaded the codes. Just wanna confirm, are those codes for each router all openwrt? Im not a developer, btw

You don't need to be a programmer to open the archive and look inside

I downloaded 841n n there wasn't any folder with openwrt

I downloaded 841n and there wasn't any folder saying openwrt.

No, they use open software, but not OpenWrt.

For sure? I recently bought a TP-Link RE205 repeater. Of course I want to use OpenWRT again;). So I inspected the device and the firmware. I would say that it is based on OpenWRT.

The extracted firmware gives some hints.

$ cat etc/openwrt_release
DISTRIB_RELEASE="Attitude Adjustment"
DISTRIB_DESCRIPTION="OpenWrt Attitude Adjustment 12.09-rc1"

TP-Link firmware is based on SOC vendor's SDKs which are in most cases based on OpenWrt.
This is true at least for QCA and MTK.


Even if an OEM uses firmware based on OpenWrt, that doesn't necessarily mean that you can run the open-source OpenWrt on the device, as @pepe2k alludes to with the mention of SDKs (which are often proprietary and tied to a specific kernel).

Looks like I was wrong...

Did you manage to install OpenWRT on TL-RE205? I recently bought one.

I had to hack into the original firmware. That was very simple, but I do not know if the release of an exploit in this forum is allowed. Afterwards I tried to build a firmware for Openwrt with the gained information. I did something wrong, the device did not boot anymore. I brought it back.

Sorry, I was hoping to give something back to the Openwrt community.

I will note that IQrouter from Evenroute uses a customized OpenWrt build, specifically to produce a ready-for-consumer SQM installation. (You can buy 'em on Amazon. I've used them - they work well). They use a TP-Link Archer C7 as the actual hardware - perhaps that's where you heard that "TP-Link uses OpenWrt".
