Byt default the wireless interface operates in the station mode. I am not sure if the SSID/key config should be the same SSID as the AP. This would make sense since the station could connect to the AP.
The default value probably changed over the years. My understanding was that OP wanted to set the device with wired uplink. Therefore Station mode shouldn't be used
But how come this help "extending the AP functionality" that OP requested? Could the station help to forward data to the AP? If so, which functionality it uses? I think the station-presudobridge mode fits better here.
I couldn't find the quoted text in OP's messages so I assume it is just misunderstanding on your side. What you are describing can be named as "wifi extender/repeater/mesh" - that means both uplink and downlink is wireless with option of additional wired downlinks. Thats where
would make sense. Otherwise (with wired uplink) we are talking about a simple AP (thats what this topic is all about) and therefore
is the right choice.
is not usual in home environment. It generally means that your uplink can't be bridged, so either your local network is routed to uplink (e.g. behind NAT with DHCP server on the station), or you use some tunnel (e.g. EoIP) to provide L2 uplink
...This would explain why the user Mattteas does not see any wifi. Just change the mode to Wireless AP and it works.
You are most certainly correct. I have updated my code to make it working again and tested it in current long-term 6.47.9. Thanks for pointing it out!
PS: word of advice - check your typos before submitting your text :-P makes it easier to understand. Also, it gives me less reasons to cyber bully you.
