Linksys WRT3200ACM 3 antennas ssid help


First day ever on OpenWrt. I'm so lost.

My Linksys WRT3200ACM AC3200 MU-MIMO Gigabit WiFi Router has 3 'antennaes' with 3 different frequencies.

I set the 2 something to my main SSID. I set the 5 something to my separate SSID (with a 5 at the end of the name).

Everything seems to work Ok as far as connecting all my devices to my router.

But it shows me that one anetanne (bottom) is at 0% so I'm guessing it's not setup properly or broken?


Thanks in advance.



The third radio (radio2/Marvell 88W8887) is a 1x1:1 internal antenna. In the stock Linksys firmware, it is used for detection of radar emissions from Weather Doppler Radar, Aeroports, Military Installations, & Amateur Radios as part of its DFS (Dynamic Frequency Selection) certification for operating at 5GHz CH 52-144. People don't really recommend using it for anything other than IoT or low bandwidth devices given that it has a relatively short range.

I suggest that you read this thread to figure out how to enable radio2 from the SSH/CLI. The post that is relevant is this, but I suggest you read through the whole thread to understand some of the quirks in setting it up.

Disclaimer: I do not own the 3200ACM. I own the 1900ACS and build custom OpenWrt images for it, reading the forums for researching what settings and features/optimisations to put in my custom image often lead me to threads with other WRT AC devices.


Well said @ParanoidZoid. I have a WRT3200ACM and just leave radio2 disabled.

Thanks SO much for your help. From what I read on here it seems that it's best to just turn it off.

Thanks again.
