I am attempting to setup an AP on wlan0 and bridge eth0 and wlan0 to get Internet access. I tried to use hostapd. It runs but throws errors and no client can ever connect to it. Software is upgraded through today, 3/16/22.

So I'm doing the following:
ip link add name br0 type bridge
ip link set dev br0 up
ip link set dev eth0 master br0
ip link set dev wlan0 master br0

The above returns the error: device cannot be enslaved...

So I need an AP with Internet access...

Any help appreciated.
