OpenWrt Firmware for Archer c6 v3.2

Wondering how to get the Stable release instead of the Snapshot.
I've been using Snapshot for about a month but there are issues.
Can I just use the A6 V3 binary from release or do I need to patch and rebuild ?
I'm guessing the lazy option is to wait for 21.02.1 however that can be another 6 months.

Unfortunately the Archer C6 v3.2 has not been commited to the 21.02 branch yet. I just confirmed that it is not available in the "make menuconfig" in the 21.02 branch.

Therefore for now using Snapshot builds is the only option.

However I am not sure about installing the OpenWRT build of Archer A6 v3 build on the C6 v3.2. I have never tried, but since the stock firmware for the A6v3 and the C6v3.2 are exactly the same, I believe here is a chance it should work with OpenWRT as well (someone has to test it! :slight_smile: )

[Openwrt newbie here]


I used your stripped file to revert my device to default (using sysupgrade ...) and it worked! (In fact it preserved my old configuration).

I tried to use openwrt-ramips-mt7621-tplink_archer-c6-v3-squashfs-factory.bin , install the sysupgrade and then luci but i wasn't able to login, so i returned to stock. Anyone have accomplished it?


Thank you for confirming that the stripped stock image allowed you to revert the Archer C6 v3 back to the stock firmware!

Upon the first OpenWRT install, the default logon is "root" with a blank password. If you are unable to login this way, you may try to perform an OpenWRT factory reset.

To do so, after the device is powered on and you are able to see the OpenWRT logon screen, press and hold the "Reset" button in the device for at least then seconds and release it. This should clear all OpenWRT settings and remove any previous password. More details in the OpenWRT wiki here.

Oh, i did that, however the Luci interface didn´t show (my browser show that server sent an empty response). I followed the instructions in:

I made a little bit of research and found that installing the package luci-ssl-nginx (instead of all others) allowed me to see the GUI but it didn't allow me to gain access due ¿main? faile damaged of XHR request timeout.

Just installing LuCI and accessing via http (not https) should work.

It might be an issue with the recent Snapshot builds (see SNAPSHOT: LuCI will not launch r17571 and r17581 on WRT1900ACv1)

I think we will need to build a stable release binary as snapshots are unpredictable.

Yeah, was that... i tried yesterday with new snapshot and it worked since then.

5Ghz sometimes refuses to work, but i supose beacause ...well,snapshot.

Is any developer still working on adding this router to the 21.02 head to be included in a future 21.02.1 stable release?

Since the updated m76 drivers broke Wifi 5Ghz on this device and others devices (see here), it would be good to have it on an stable branch just as A6 v3 and C6U are already in 21.02.0 stable release.

BTW, I just realized that there are no internal pictures of this device on the web, so here you go:


Hey All,

I installed the latest snapshot and I cannot turn on wifi after that.
Even did the setup using uci

@dsouza I noticed the C6 V3 didn't make to the latest stable release of today.
Do you know if there is differences between C6 an A6 ? I heard A6 being Amazon exclusive clone of the C6. Are you aware of any differences ?

As far as I know they are the same device. I believe that flashing OpenWRT A6 v3 firmware on the C6 v3 could work, but I would not recommend it unless if you have an UART and skills to open the device and recover it via serial console (since it may brick your router).

Anyway, I am willing to try this during the weekend... :slight_smile:

I just flashed 21.02.1 Archer A6 v3 image on an Archer C6 v3.2 device and as expected it is working.

I had to "force" a sysupgrade from OpenWRT snapshot since it detected it was a different device. But the upgrade went OK and everything is working fine (obviously it started showing "TP-Link Archer A6 v3" on the status page.

Notice however that I (forced) flashed from OpenWRT snapshot C6v3 to OpenWRT 21.02.1 A6v3 using squashfs-sysupgrade image and I can confirm this works fine. However if you are flashing from stock firmware I cannot say it would work applying the A6 v3 squashfs-factory on a C6 v3.2 device. I think it would work but I have not tested.

when will be stable version for this router? I mean LuCi preinstalled.

I tried to cherry pick these changes into 21.02 (#4280) but it seems they were rejected I have since lost track of the release. Not sure how to get that included once multiple releases are out.

Idk what to say,it is sad and bad for community.I was decided to purchase it.Because is cheaper then C6U.

I have instaled the snapshot version from 3 weeks ago, but last week I have tryed to upgrade to the last snapshot, but after that it starts to boot loop. But I can´t have the TFTP working to install a new firmware. Can anyone help me how to unbrick it?

Have you identified the serial port?

It's a known issue due to a Wi-Fi problem in some builds. This has already been resolved in the more recent builds.

To recover from this you must enter in Fail Safe mode by pressing the reset button before boot while power is flashing slowly and flash a more recent build.
