Broadcom BCM6358 on 19.07.3


I'm on: OpenWrt 19.07.3 r11063-85e04e9f46

I have created two wifi networks. Either one or the other will work, not both at the same time. I get "Wireless is not associated" when both are enabled.
Is this still a limitation of the Broadcom BCM6358 driver, or was this fixed and I don't know how to configure the wifi?

Thanks for your considered input.
