Adapters with multiple radios for dual/tripple-band AP?

[bdew]

I'm a bit new to this so sorry if this is a stupid question.

I have an arm sbc that i use as a home router, and i want to add a wifi access point to it with a USB dongle.

I got a EDUP EP-AX1672 which is tri-band but it has only one radio so i can only run hostapd on one band at a time.

Is there such a thing as usb dongles with multiple radios? Or should i get separate dongles for each band?

Hi @bdew

Not as far as I know.

Or should i get separate dongles for each band?

That is the common thing to do. Keep in mind that 6 GHz just does not work everywhere. For example, using a USB adapter for 6 GHz in the US simply does not work because of the wireless regulations. To get it to work will necessitate changes to the regdb.

The old RTL8192DU could do it, but it was abandoned a long time ago and it can't be found anymore.

The RTL8852AU, RTL8852CU, and RTL8922AU maybe can do it using the vendor drivers.
