Kann ein Intel Wireless 7260 als Access Point fungieren?

OK, it is actually possible, using hostapd (and dnsmasq).

I've used a mix of the following links:

• https://arsprogramming.wordpress.com/2014/01/15/wi-fi-hotspot-on-ubuntu-13-10/
• https://nims11.wordpress.com/2013/05/22/using-hostapd-with-dnsmasq-to-create-virtual-wifi-access-point-in-linux/

Sharing eth0 with address 192.167.1.27/24 and dns server/router 192.167.1.1

On wlan with address 192.168.0.1/24

First, you must install dnsmask and hostapd by typing in terminal: sudo apt-get install hostapd dnsmask. After that, you must stop those services, by typing sudo service hostapd stop and sudo service dnsmasq stop. Also prevent them from starting at startup:

sudo update-rc.d hostapd disable
sudo update-rc.d dnsmasq disable

my /etc/dnsmasq.conf:

Start:

sysctl net.ipv4.ip_forward=1
service dnsmasq restart
iptables -t  nat -A POSTROUTING -o eth0 -j MASQUERADE
hostapd /etc/hostapd/hostapd.conf
