Raspberry pi4, one wifi in ap+sta mode

Installing and Using OpenWrt Network and Wireless Configuration

Hi all,

I want to use rpi4 with its' own wifi adapter in ap+sta mode.
Aim is to make travel VPN router where sta connects to any wifi network and I connect to the AP.

Can this be done?
All examples required second wifi adapter on the rpi4.

I have a small wr802n tplink with one wifi card and it does it, but it's very slow.

There's probably a reason why all those examples use a 2nd adapter.

AP+STA is not supported on the Raspberry Pi internal radio. AP or STA is allowed but not both at the same time.
