create your hostapd.conf: "vim /etc/hostapd/hostapd.conf "
hostapd.conf (236 字节)
According to your network interface(can search internet) to config ap0:
my network interface which can search internet is wan, and ip is 192.168.30.102, so I config ap0 as follows:
“ifconfig ap0 192.168.30.188 netmask 255.255.255.0”
Run hostapd : “hostapd -d /etc/hostapd/hostapd.conf”
Config dhcp file : “vim /etc/dhcp/dhcpd.conf”
subnet 192.168.30.0 netmask 255.255.255.0 {
range 192.168.30.2 192.168.30.250;
option domain-name-servers 8.8.8.8;
option routers 192.168.30.1;
}
Config dhcp of ap0, then the devices which connect ap0 could get IP: "dhcpd ap0 -pf /var/run/dhcpd.pid "
And a bridge
brctl addbr br0
brctl addif br0 ap0
brctl addif br wan
Config br0 : “ifconfig br0 192.168.30.180 netmask 255.255.255.0”
Add br0 gw as : “route add -net default netmask 255.255.255.0 gw 192.168.30.1 dev br0”

Hi, can anybody confirm, that wifi in AP mode is stable?
I bought 2 pieces of Banana Pi. The first one was R1. The second one is R2.
It was the worst purchase I’ve ever made. R1 in AP mode will always be unstable.
I hoped, that R2 is solved and Wifi will be stable. The board has several ethernet ports - it could be good router. Everybody is expecting, that AP mode and ethernet works. It is like purchasing a new car for travelling and producer forgot to say, that the car is without engine…
Banana R2 bought in december 2017 and now is AP mode still unstable. I tried several tips, I’ve read several discusion. I found this release: BPI-R2 New Image Release : Ubuntu 16.04 V1.3 2018-3-30
With text: Known limitations - Wifi Ap is unstable. OMG - how is it possible? This information should be on the package. BPI-R2 - warning - do not use for networking…
You can see, that I’m irritated from this product and driver support. The question is. Is wifi in AP mode stable or unstable?

My r2 is running 50 days with ap enabled (4.14.34),used everyday and is only 1 time restarted because of a channel-change (my neighbour changed before so i got overlapping channel with bandwidth-reduction). Some people have problems with random-number-generator…
Hi Frank. Thank you for your response. And how many devices do you have connected?
I will try this image, I will see.
I have network with several devices - MacOS, Android, Windows 10 (8 devices).
It seems, that after connecting windows 10 - wifi AP is broken. But not this image. My last kernel is: Linux bpi-iot-ros-ai 4.4.126-BPI-R2-Kernel
So I will try this kernel. My last try
