Is it possibel to use Superchannels on a X86 system aor only on RB? TIA

It's available from RouterOS 4.3 on all platforms.

The only thing not available on x86 version of RouterOS are NV2

Thanks fo your response, but are you 100% sure? I have a X86 system running ROS 5.23, but it does not have "Frequency mode" under the Wireless section. Have you tried it on a X86 system. I can see it on a RB. Pls confirm.

For see "frequency-mode" you must click first on the button on the bottom "Advanced Mode"...
I can not confirm on 5.23, I have 6.7 on my x86.

You also must have compatible atheros chipset!!!
I do not know all the single chipset vendors and models supported.

Silly me. I see it now.

I read that you need chipset AR92xx to be able to use this feature on oth ends. Can someone recommend a good high power 5Ghz card that uses the AR92xx chipset or better. TIA
