Support for TP-Link Archer C2 v3

VMax2 · April 17, 2019, 4:33pm

Well i answere by myself i installed the new firmware uploading Dreadlish's files and all went well, so now the Archer C2 V3 is running OWRT like a charm but...
I tested the wifi performance in 5 Ghz and 2.4 Ghz too and i can say that's realy poor...
Making a speed test over the internet i have 49 Mbit/s down and 62 up in 2.4 Ghz , 104 Mbit/s down and 73 up in 5 Ghz when by ethernet i have 323 down and 165 up and if i connect to the main router in wifi i have 147 down and 172 up...
I don't know if there is something to do but if not then i will have to roll back to the original firmware...

Today looking into the log file i fount that there are some kernel errors, some user notices, some user errors, some daemon errors and a lot of kernel warnings...
So i think this firmware is far from being optimized for this device...

I add a cut off with all the errors in the log file:

My Archer C2 keeps crashing pretty rapidly, I believe there is a memory leak somewhere:

Running latest snapshot: Sat Apr 20 09:38:16 2019
sha256sum ec063182807c93b56c53564b9da89a183319bc86f8c361580ede09e7b8779a10

It's completely unusable at this point and I have no clue how to get back to stock firmware. Let me know if I can help with debugging!

Edit: It appears that disabling the 802.11nac interface fixes the mem leaks!

Sharky · April 26, 2019, 12:55pm

I opened a bug about this: https://bugs.openwrt.org/index.php?do=details&task_id=2260

Entropy512 · April 26, 2019, 2:17pm

Does the problem disappear if you switch from ath10k-ct to ath10k? (Assuming you're using the default of -ct drivers and firmware)

Dorin · April 27, 2019, 5:58pm

For me, the performance is much better with the ath10k driver/firmware, memory usage is much lower, but there is a warning that is flooding the kernel log ( no problems with the wireless connection):

Would these work on an Archer C900(US)?

Thanks

Sharky · May 31, 2019, 10:24am

I followed your advice and made a custom build with ath10k (non-ct) and it seems to work flawlessly.

To those who wish to reproduce this, here's my patch for building a non-ct image:

DEVICE_PACKAGES can be overridden in .config, no need to patch the .mk file as far as I can tell - definitely was not necessary for my C2600

Sharky · May 31, 2019, 3:02pm

Good to know, thanks!

I've created a image using the image builder.
Download from: http://downloads.openwrt.org/snapshots/targets/ath79/generic/
https://openwrt.org/docs/guide-user/additional-software/imagebuilder

My recipe (including luci):
make image PROFILE=tplink_archer-c2-v3 PACKAGES="luci kmod-ath10k ath10k-firmware-qca9887 -kmod-ath10k-ct -ath10k-firmware-qca9887-ct"

Hello, I am using your image but I have the following error when trying to install openvpn-openssl:

Please help.

I am not sure I understand how exactly I can do it same day.
I used this to flash router : http://downloads.openwrt.org/snapshots/targets/ath79/generic/

I just reflashed again using factory.bin from openwrt luci gui.
and I tried again to install openvpn few minutes after
Does it count as same day?

Or maybe I need to flash with factory.bin and then again with sysupgrade.bin and then install openvpn?

Falcon1 · October 12, 2019, 6:41pm

Hey Wolf,

With snapshot this happens every once in a while. They are build almost daily.

You should wait a day or few before downloading a new image (builder). I had similar issues with the imagebuilder at first, probably because of dependency errors, a week later the problem was gone.

In the downloads page you can see from which dates they stem.

Good luck.

gr0ebi · January 21, 2020, 8:25am

I've used the Non-ct, still got wifi bugs. (Cant connect to wifi sometimes)
Any updates on this topic?

Optikingz · January 21, 2020, 11:35am

Still OOM issues with newest build.. from stability perspective the build from dreadlish was/is the best..
@Dreadlish maybe u could build a new version for those who cant build it self.

This topic was intended for adding support for this specific device.
Since official 19.07 images are available since quite some time, I will set a timer for this topic to close.

Therefore: Please open new topics for any open issues with this device.
