Hello I'm trying to use the raspberry pi 3 built in hardware to create two interfaces and access points. I believe my configuration is correct according to the examples I've seen but when I add the 2nd SSID to the config it fails to start. Below is my configuration. I appreciate any help! dave interface=wlan0 driver=nl80211 ssid=QStaff country_code=US channel=11 bss=wlan0.1 ssid=QCustomer auto lo iface lo inet loopback iface eth0 inet manual auto wlan0 iface wlan0 inet static address 172.16.0.1 netmask 255.255.255.0 up ifconfig wlan0 hw ether b8:27:eb:51:c6:00 auto wlan0.1 iface wlan0.1 inet static address 172.16.1.1 netmask 255.255.255.0 up ifconfig wlan0.1 hw ether b8:27:eb:51:c6:02 Log messages root@raspberrypi:~# hostapd -dd /etc/hostapd/hostapd.conf random: Trying to read entropy from /dev/random Configuration file: /etc/hostapd/hostapd.conf rfkill: initial event: idx=0 type=1 op=0 soft=0 hard=0 rfkill: initial event: idx=1 type=2 op=0 soft=0 hard=0 nl80211: TDLS supported nl80211: Supported cipher 00-0f-ac:1 nl80211: Supported cipher 00-0f-ac:5 nl80211: Supported cipher 00-0f-ac:2 nl80211: Supported cipher 00-0f-ac:4 nl80211: Supported cipher 00-0f-ac:6 nl80211: Using driver-based off-channel TX nl80211: Supported vendor command: vendor_id=0x1018 subcmd=1 nl80211: Use separate P2P group interface (driver advertised support) nl80211: Enable multi-channel concurrent (driver advertised support) nl80211: interface wlan0 in phy phy0 nl80211: Set mode ifindex 3 iftype 3 (AP) nl80211: Setup AP(wlan0) -
