Adding OpenWrt support for Archer A6 v3

dsouza · August 30, 2021, 12:52am

Since I can easily replicate the problem, is there a place I can look for any error?

I am checking logread and dmesg, and no error is shown when the radio stops. I've also tried to increase hostapd log level to "debug" and still no error is shown. The radio just stops, and I have to reboot the router to restore it. But the issue only happens when two or more wifi clients are transferring lots of data simultaneously.

BTW, another issue (minor for me). I noticed that if I change SSID without rebooting, for some reason the clients can see and initially connect to the new SSID, but they are unable to communicate. A reboot is also needed to solve this problem.

To me it all seems related to the Wifi driver. I understand from @Borromini 's comment above that we should get mt76 "gold" drivers at some point in time. Hopefully this would help with these issues.

I was referring to 21.02 getting its release, at which point I intend to offer mt76 packages with the hack included.

I got a c6 v3.2 and with this bug, mesh is useless. However, I am able to use my clients without too many problems with this snapshot: r17245-ac4e8aa2f8 ... and I programmed a daily auto-reboot at 4AM which seems to make it last for almost a day without issues. I am using that router with sometimes around 6 5GHz clients on a link ~200Mbps.
I have another router that has connectivity issues and built this crappy python script executed on it via a cronjob every 2 minutes:

import os
import datetime
import subprocess

MAX_LATENCY = 10
PING_COUNT = 3
SERVER_IP = '192.168.10.1'
RESTART_CMD = 'killall -HUP wpa_supplicant && sleep 5 && wifi up'

def ping(server='example.com', count=1, wait_sec=1):
    """

    :rtype: dict or None
    """
    cmd = "ping -c {} -W {} {}".format(count, wait_sec, server).split(' ')
    try:
        output = subprocess.check_output(cmd).decode().strip()
        lines = output.split("\n")
        loss = lines[-2].split(',')[2].split()[0]
        timing = lines[-1].split()[3].split('/')
        return {
            'type': 'rtt',
            'min': timing[0],
            'avg': timing[1],
            'max': timing[2],
            'loss': loss,
        }
    except Exception as e:
        print(e)
        return None

if __name__ == '__main__':
    print(datetime.datetime.now(), 'connection check')
    ping_result = ping(server=SERVER_IP, count=PING_COUNT)
    if not (ping_result and float(ping_result['avg']) < MAX_LATENCY):
        print(f'ping average is worse than {MAX_LATENCY} ({ping_result})')
        os.system(RESTART_CMD)
    else:
        print(f'connection stable: {ping_result} ')

A watchdog

darksky · September 1, 2021, 11:21am

I am fine building my own firmware. Is the patch I need to apply this one? If so, is there an example Makefile for the corresponding package you can share with me so I ca build it?

Borromini · September 1, 2021, 12:18pm

Nope. This is a ready made patch that you can apply to your OpenWrt git tree. Then recompile the mt76 package.

darksky · September 5, 2021, 9:38am

@Borromini - I patched the latest HEAD but got build errors. Any thoughts?

Borromini · September 5, 2021, 11:08am

@darksky Is that on master? Mt76 might have seen changes that break the patch. Might be better to ping ptpt52 in the bug report he opened, see his post with the hack.

darksky · September 5, 2021, 11:11am

Yes, it's on master. Interestingly, I just reverted the patch and found that I could not build it. Are you able to build the latest commit from master?

darksky · September 5, 2021, 3:04pm

@Borromini - It seems that patch is applied by default to the 21.02.1 image, but running that, I still trigger the bug.

Borromini · September 5, 2021, 3:16pm

It's not, otherwise my build would break when applying that patch. Just check the git tree:

I'll try a master build when I have the time, at least the patch still applies cleanly to master (checked with a make prepare).

darksky · September 5, 2021, 3:51pm

git checkout v21.02.0 after I updated the feeds showed the patch is present. I built 21.02.0 with the patch applied but still have the bug. I built it with the kmod-mt76 enabled "MediaTek MT76x2/MT7603 wireless driver (metapackage)" ... is that right?

Borromini · September 5, 2021, 5:51pm

What does git status show? I bet that patch shows as an unmanaged file. Which means it's not part of the tree.

darksky · September 5, 2021, 7:02pm

It was my mistake... I tried previously to copy a version of it over. It is not an officially unstaged file

To me the key point is that when I do apply it to 21.02.1, it doesn't fix the bug.

ikrogan11 · September 6, 2021, 6:29am

I purchased this router and my stock tp link firmware is currently 1.0.5 , there is an update available ( firmware 1.0.10 ) from tp link. So should I update tp link firmware before flashing with openwrt or is it ok to flash on the stock firmware?

Borromini · September 6, 2021, 9:56am

New firmware might have new checks, so don't upgrade vendor firmware before flashing OpenWrt.

tmomas · September 6, 2021, 10:04am

This topic was intended for adding support for this specific device.
Since official 21.02.0 images are available now, I will set a timer for this topic to close.

Why?

Because specific problems for this device with official releases are better handled in separate topics, in order to make finding relevant information easier. Who is going to read the previous 100-something postings, if he has a specific problem with 21.02.0 and wifi?

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

Thanks!

dsouza · September 9, 2021, 11:06am

This topic has been also used for Archer C6 v3.2 issues (same hardware as the A6 v3) which is not yet included in the official 21.02.0 builds. Anyway I believe there is another topic we can continue the discussions about the C6 v3 if needed. Thanks!

dsouza · September 10, 2021, 8:40pm

I have two TP-Link Archer C6 v3.2 being used as Access Points, both are running a custom build from master (r17470-43f0e386d4 - I just removed a bunch of packages that are not required for access point such as dnsmasq, firewall, ...).

So far they are working OK with some bugs as already discussed in this thread (some instability with 5Ghz radio and reboot required after changing any wi-fi configuration).

Looking at dmesg I've noticed something odd. The size of the "kernel" partition and the start of the "rootfs" partition are different between these two devices (which are exactly the same models).

While they are working fine, I'm wondering what could cause this difference since they are exactly the same model/revision.

The only thing I recall I did different was that for "Device 1" I've upgraded the stock firmware before installing OpenWRT, while on "Device 2" I've installed OpenWRT right out of the box.

Any thoughts?

AFAIK splitting is dynamic, so it's not abnormal to have differing kernel & rootfs sizes if you're not running the same build on both devices. Are you?

The kernel 'partition' expands to what's needed for it AFAIK (within certain limits) and the remainder is allocated to the rootfs.
