[SOLVED]Linksys WRT32X - three radio modules

Linksys WRT32X has three radio modules:

  • radio0 Marvell 88W8964 802.11nac (5.180 GHz)
  • radio1 Marvell 88W8964 802.11bgn (2.462 GHz)
  • radio2 Marvell 88W8887 802.11bgnac (5.180 GHz)
    What is the third module radio2 and how it possible simultaneously support b/g/n/ac if they use different frequency 2.4Ghz and 5Ghz???

After reading this link I made conclusion: disable radio2 and forget about it.

I don't know if passive scanning is supported in Openwrt. This way you could make use of it.
Otherwise you've done right.

The third radio can be configured as 2.4GHz or 5GHz, but not both at the same time.

Which benefits I can get from it?

Amusement, mainly :wink:

It potentially could be used as a monitor with something like

config wifi-iface
        option device 'radio24'
        option mode 'monitor'
        option ifname 'mon24'

If you were ambitious, you could use the results to implement dynamic, automatic channel selection or something of the sort.

Do you mean?

        option device 'radio2'

I don't use the default naming for my radios, as I can never remember which is 0, 1, or 2. If radio2 is how that is defined in your config, then, yes, radio2. The ifname I also provide for my convenience.
