I am trying to configure my opensuse 13.1 system to function as a hotspot (on my dell xps13 computer).

So I tried setting up hostapd as explained here, but I get an error:

hostapd /etc/hostapd.conf
Configuration file: /etc/hostapd.conf
nl80211: Failed to set interface wlp1s0 into AP mode

The problem might be with the driver. Perhaps I should indicate another one, since:

>> lspci -k | grep -A 3 -i "network"

Some more netcard info:

--update: I checked that my card supports AP like this:

Thanks for any insight and suggestions. I really need to set up a wireless hotspot, so I am hoping that somebody can help me solve this.

--update

I have executed the following commands error free:

   nmcli nm wifi off
    rfkill unblock wlan

    ip link set dev wlp1s0 up
    ip address add 192.168.5.1/24 dev wlp1s0

    iptables -t nat -A POSTROUTING -s 192.168.5.0/24 -o enp0s20u2 -j MASQUERADE
    sysctl -w net.ipv4.ip_forward=1 1> /dev/null

    systemctl start hostapd.service
    systemctl start dnsmasq.service

My /etc/hostapd is:

interface=wlp1s0
driver=nl80211
# bridge=br0
channel=3
hw_mode=g
auth_algs=1
ssid=test

My phone sees the test network. But keeps saying "Obtaining IP address...."

I feel that I am very close now...

Did you start a DHCP server? DNSMasq doesn't enable its DHCP component by default. Try editing your /etc/dnsmasq.conf file to enable DHCP and restarting the service, or give your phone a static IP address. –  hololeap Jul 7 at 9:21

If you follow this guide exactly you should find success:

http://www.cyberciti.biz/faq/debian-ubuntu-linux-setting-wireless-access-point/

I have used the guide on Ubuntu 14.04 server.

Be careful when you cut and paste into a ssh client or PuTTY terminal. I had to delete extra spaces that were inserted and it brought up errors, sorted that out and all was well.

Currently trying to extend this guide with scripts to change interfaces, when virtual machine security appliance fails - it will start the WiFi network up with a bridge to the modem to bypass the security appliance.
