I feel a bit lost about my Raspberry... so I will start at the beginnign to avoid asking the wrong question.
My Plan is:
Raspberry can plug in to network via network-Cable -> Works like a charm.
Raspberry gets a Wifi-Dongle to open a WLAN-AP. I basically followed this HowTo, and it worked.
Now, the idea is: The Raspi get a static Ip-adress on it's own WLAN!
That's where I fail.
I seem to have two issues:
- I cannot get a static IP to the wlan0
- I am not 100% sure if wlan0 SHOULD be the one with a static ip? Or should br0 be gettign a static?
My Theory is that when I have a 192.168.0.xxx-network already running (from my normal internet-acess), I should be able to open a 192.168.12.xxx-network (12 is just an example... just something that is not 1). Am I right here, and if yes: how do I "explain" that to my Raspi?
PS: I reset the Pi out of desperation and fear to have messed somethign up... currently, hostapd.conf etc do not exist.
Additional Info per comment:
I have the normal ethernet eth0 interface wlan0 , the wifi dongle.
And, per instructions from the linked page, br0, which (as far as I understand it), is supposed to provide the bridge between eth0 and wlan0 so I can connect to the internet via the raspi.
