OpenWrt Firmware for Archer c6 v3.2

Wifi physical turn on or off button working on rc5 ?

Can confirm it turns the device on or off as expected

Ok I have moved on to compiling an image from source and setting custom packages and options when compiling after making sure the rc5 LuCi build works well. When setting up the compilation options I target "TP-Link Archer C6 V3" and as far as I am aware this sets up the default required firmware and kernel modules for this router. Indeed, I was able to compile the image, flash it, and edit the /etc/config/wireless file to enable the two radios. Yet only the 2.4ghz seems to work, and poorly at that, it's led flashes constantly, and the 5ghz one is on permanently, I can only see the 2.4ghz on my windows machine, and when I attempt to connect, it stalls in some kind of loop, and I can't ssh using that connection (Ethernet works fine though).

Running logread I get the following at the start:

daemon.err procd: Could not find firmware /lib/firmware/mediatek/mt7663pr2h.bin: No such file or directory

When I manually download this firmware from the repo and place it where it is supposed to go, I get other problems related to the 5ghz, not sure if it is relevant, but in any case I am currently focusing on trying to fix the 2.4ghz, oddly enough, there is no other warning or error message in my logs, radio0 and wlan0 start up fine, and at the end when I try to connect, I get the following loop:

daemon.info hostapd: wlan0: STA aa:2c:b4:82:d9:72 IEEE 802.11: authenticated
daemon.info hostapd: wlan0: STA aa:2c:b4:82:d9:72 IEEE 802.11: associated (aid 1)
daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED aa:2c:b4:82:d9:72 off

This repeats indefinitely. Any ideas on what I may have done wrong? This is my first time compiling from source but I made sure to do it properly and configure the options in the right order, in any case I am building off the same target that all the release candidates build off of, so maybe analyzing this problem will help fix some of the problems others have with both 2.4ghz and 5ghz.

They silently released a new version for this C6 v4 series: https://www.tp-link.com/in/home-networking/wifi-router/archer-c6/v4/

Comes with a 1.2Ghz Dual Core CPU.

Edit 1: 400Mbps on 2.4Ghz

Yes.... TP1900BN (Mediatek MT7626B(N)) same for TP-LINK Archer C64

Was discussing with a friend and he told me that on flashing the c6u firmware on c6, he gets above 450mbps on wifi but with c6's own firmware or a6v3 stable firmware this is not possible.
Any insights here?

Didn't expect that to actually work but C6U firmware flashes successfully, wireless also functional (cannot test performance at the moment)

This is on RC6 archerc6v3

Laptop Wifi:

    Description            : Intel(R) Dual Band Wireless-AC 8265
    Radio type             : 802.11ac
    Channel                : 36
    Receive rate (Mbps)    : 866.7
    Transmit rate (Mbps)   : 866.7
    Signal                 : 97%

iperf3 receive mode (wired desktop>switch>archerc6>wireless laptop) (4 parallel streams)

iperf3.exe -c 192.168.0.20 -P 4 --omit 10 -t 70 -i 10 --reverse
result:
[SUM]   0.00-69.99  sec  3.95 GBytes   485 Mbits/sec                  receiver

iperf3 send mode (wireless laptop>archerc6>switch>wired desktop) (4 parallel streams)

[SUM]   0.00-69.99  sec  3.60 GBytes   442 Mbits/sec                  sender

So even though it claims to be connected via 866 Mbits this is what I get.

Thanks a lot for the clarification.

WiFi is half-duplex, so getting ~500Mbps on an 866 device is expected result.

Can you share the load average of the CPU of the C6, while the iperf is running?
If possible, run the iperf for 2 minutes.

e: For clarification, this is without any firewall/routing applied, Archer C6 v3 running 22.03 RC6 in Dumb AP mode.

Thanks, so it looks like it can act as a SOHO router for connections up to 500 megs.

Is there an easy way to turn on the orange wan when internet is lost and green when present?
I tried using luci-app internet detector with custom scripts but it works spotty at best and not at all at its worst.
