The dsl-router is too far away. I cannot get a wireless Signal from the router.
I set up the 'tethered access point" but then I can only connect my Smartphone to my RPi3, but not my Smartphone to the Internet via the tethered connection (phone -> Rpi3) and the wired connection (Rpi3 -> Internet/DSL-router).
to be a bit moe specific:
It seems that eth0 (wired connection) gets its IP-adress from the router's DHCP-server.
But wlan0 (the wireless Connection) creates a new IP-Adress (192.168.0.1)
