Wifi-Hotspot Project | Troubleshooting

[Malak410]

Hey,
I’ve got a problem opening a hotspot on my raspberry pi 3 with my wifi-stick from Edimax (EW-7612UAn V2).

I want to create something like this:

IF eth0 available (Ethernet Connection) THEN connect the raspberry pi (with eth0) with the Internet and open a hotspot at my Wifi-Stick (wlan1) ELSE connect the raspberry pi with the Internet with the onboard Wifi-Chip (wlan0) and open a hotspot at my Wifi-Stick (wlan1)

What do I have to do?
I already followed this Tutorial: http://blog.claytonn.com/raspberry-pi-c ... mment-4309

How can I realise my project?

Regards

I think you could attempt to bring up both internal interfaces and use the ifmetric package to give eth0 a higher priority. If it's down it will be discarded. No condition to deal with, and you get a backup link.

Then as far as I see you start wlan1 in any case, so no need to make startup conditional either. Unless I don't grasp what running a hostpot implies compared to a simple access point.
