There is a 3rd "hidden" radio in this model. I belive it was reserved for radar detection. As radar detection uses band 2 and a bit of band 1 of the 2.4/5GHz spectrum, there is overlap into WiFi. Indeed,In DD-WRT fw the radio shows up as "ath2" device and is fully configurable and works perfectly with my 5GHz wifi clients. So having three radios is fantastic , tri band! , and I can distribute clients across the 3 bands to maximse throughput/efficiency.

However, this thirs radio doesnt appear in OpenWrt , LEDE or any derivative.

Could we get this functionality in please.

It is already there in Openwrt/LEDE master.

The functionality was added to LEDE master in March 2017.
The five last commits here:
https://git.openwrt.org/?p=openwrt/open … 30547bd5a0

But I keep that radio disabled on my own3200ACM.

There is also discussion about that radio in the forum:
https://forum.lede-project.org/t/third- … 00acm/2293
https://forum.lede-project.org/t/wrt320 … ation/9218

I posted because the radio doesnt appear

I flashed the latest 2018 'generic' build

What screen should it appear on?
It isnt  on the list of radios that can be edited, deleted, enabled etc?

If appears quite normally as an editable radio along the two main radios.

But you maybe need to first delete the /etc/config/wireless and let it be generated again, so that all radios get added to it.

ok, will try tonight. thanks

Check it is in your build:

root@bsaedgy:~# opkg list_installed | grep sdio
kmod-mwifiex-sdio - 4.9.65+2017-11-01-1
mwifiex-sdio-firmware - 2017-09-06-a61ac5cf-1

iirc, the community image posted here has it removed due to the possible issues as outlined on the mwlwifi readme.

@ninjaef

Don't forget about antenna time, when radio's race signals on the same antenna. As previously said, the third radio is for DFS purposes.

@nitroshift Third radio on this device as its own (little) antenna.

I have used the 3rd radio
With no issues whatever or whatsoever, perfect, flawless. Operation in DD-WRT.

OpenWrt , LEDE , and David502 Linksys builds all have it removed. This is a deal killer. Three radios work perfectly on DD-WRT, trust me

So I'm going DD-WRT

In don't see anything in that link
That explains loss of 3rd radio

Anyway
DD-WRT all the way now

!!

It was not meant to explain the loss of the 3rd radio, it was meant to explain the reason that it was removed from the community build. There is a possible conflict if you configure things incorrectly, does not matter what release you use, LEDE/DD-Wrt.

If it actually is not in the stable or snapshot images(don't use them), does not take much to install the above ipk files. But I know that doing a build for mvebu targets, OOTB the third radio packages are enabled by default.
