<p>Hi, <br>
</p>
<p><br>
</p>
<p>I have installed OVS on my router and I want to connect it with a Floodlight controller. The IP address of the laptop on which Floodlight is running is 192.168.1.161 and Floodlight is running on port 6633. Here is what I am doing. <br>
</p>
<p><br>
</p>
<p>First, I start Floodlight controller (the vanilla version without any change). Then I turn on the router and ssh into it. Executing "ifconfig" on it will give me: <br>

<div><br>
</div>
<p>Specifically wlan0 is 2.4GHz wifi and wlan1 is 5GHz wifi. I want to use Floodlight to control 2.4GHz wifi (wlan0). I do not know exactly what br-lan is. So if anyone can explain it to me that would be great. <br>
</p>
<p><br>
</p>
<p>Then I use "ovs-vsctl del-br" to delete any remaining bridge so that "ovs-vsctl show" will report nothing. Then I have the following configuration file that I execute. <br>
</p>
<p><br>
</p>
<div>ovs-vsctl add-br br0;</div>
<div>ovs-vsctl add-port br0 wlan0;</div>
<div>ovs-vsctl add-port br0 br-lan;</div>
<div>ifconfig br-lan 0.0.0.0;</div>
<div>ifconfig br0 192.168.1.1;</div>
<div>ovs-vsctl set-controller br0 tcp:192.168.1.161:6633;</div>
<div><br>
However, after I execute this program, the only connection that I have is SSH. I can't browse the Internet anymore. However, my Floodlight controller shows the connection from br0 and if I were to capture PacketIn events, I can see that it receives some packets
from time to time. Nevertheless, it is more like periodic update than network request because rapidly refreshing my webpage will not significantly increase the packets received. <br>

<div>Could anyone tell me what might go wrong? <br>
</div>

<div>Thanks,<br>
