Beamforming working or not?

How do i know my routers beamforming is on and working on openwrt? in stock firmware i had the option to enable it .

My router : tp link archer c60 v3
Cpu- Qualcomm Atheros QCA9561
wlan hardware- Qualcomm Atheros QCA9561, Qualcomm Atheros QCA9886

Yes, but 2x2 limits its abilities, so you won't get that far.

Tp link advertised it as ac1350 mbps router & it has beamforming and 3x3 mu mimo.

In Status -> System Log look for lines that start with:

daemon.notice hostapd: Configuration file:

There should be two, and in one of them (the one on 5GHz), a list of enabled capabilities should include:


If you see these, then beamforming is enabled. It is enabled on Archer C6v2 with similar hardware.

But this is not a 3x3 AC device, it only has two spatial streams. It only has 3x3 on 2.4GHz 802.11n radio.

Exactly, only the 5 GHz 2x2 QCA9886 is 802.11ac -and with that Mu-MIMO- capable, the 802.11n 2.4 GHz radio isn't.

i found this on their website-

And where does it say in the text you sent that it is 3x3 on 5GHz?

dont get me wrong. i am confused. i dont know how it counts. so it has 2x2 on 5ghz and 1x1 on 2.4 ghz, in total that makes it 3x3?
or it has 3x3 on only 2.4 ghz?

It has 3x3 on 2.4GHz 802.11n (wifi 4) 40MHz hence the advertised 450Mbps, which is not achievable in reality.

It has 2x2 on 5GHz 802.11ac (wifi 5) 80MHz MU-MIMO hence the advertised 866Mbps, again not achievable in reality.

This "totals" 450+866 = "AC 1300" advertised speed.

In reality, this device (Archer C60 v3) can in an ideal situation only push ~400Mbps lan (4 ports) to wifi or 100Mbps wan to wifi as it only has 100Mbps ethernet ports.

Additionaly, in a field with no wifi networks around 2.4GHz 3x3 40MHz wifi 4 can achive about 250Mbps, and 5GHz 80MHz 2x2 wifi 5 can achieve about 550Mbps.

In an urban environment, you can expect up to 125Mbps on 2.4GHz wifi 4 as there is no way 40MHz channel is going to be an improvement over a standard 20MHz channel.


thank you so much for your nice explanation. Now it is clear to me.

in my system log i only found these lines about hostpad -

daemon.notice hostapd: wlan1: AP-STA-DISCONNECTED c0:8a:cd:c8:5a:f6
Thu Apr 4 00:51:41 2024 hostapd: wlan1: STA c0:8a:cd:c8:5a:f6 IEEE 802.11: authenticated
Thu Apr 4 00:51:41 2024 hostapd: wlan1: STA c0:8a:cd:c8:5a:f6 IEEE 802.11: associated (aid 2)
Thu Apr 4 00:51:41 2024 daemon.notice hostapd: wlan1: AP-STA-CONNECTED c0:8a:cd:c8:5a:f6
Thu Apr 4 00:51:41 2024 hostapd: wlan1: STA c0:8a:cd:c8:5a:f6 WPA: pairwise key handshake completed (RSN)

this means my routers beamforming is not turned on. how can i turn it on?

The system log is stored in RAM and uses a ring buffer - it overwrites older messages when new messages arrive. Please reboot the device and look for the lines before they get overwritten.

just after rebooting i checked, still cant find such lines :sob:

What version of OpenWrt are you using?

openwrt 22.03.5
