O2 Box 6431 (Arkadyan VGV7510KW22) Wi-Fi-Speed

The o2 Box' reliability and performance has greatly improved with v19.07, but Wi-Fi performance is still questionable.

The RX Rate for most devices is 120 and greater. The maximum combined speed the router is able to throughput via Wi-Fi is around 30 Mbit/s, though.

I already tried to move Wi-Fi to the second core but to no avail. The only way to get decent Wi-Fi throughput is to connect an AP via LAN to the router.

Are there any settings to improve Wi-Fi speed I'm missing, or is this a driver limitation?

I am now in the same situation with Astoria ARV752DPW (also ARV752DPW22) and can't find a solution.

How did you enable the second core on this device?
Did you build your own image?

You'll need to edit the DTS, in order to disable the voice core reservation and enable SMP, before recompiling an image.

Thanks @slh. I have a few follow-up questions. I'm asking them in a separate topic so that I'm not hijacking this one.
