No other devices will connect to your network, if you hard code the mac addresses of every piece of hardware in your router setup.
Limit the DHCP range, and only allow listed devices on your router.
My example;
192.168.1.254 Main Router Address
192.168.1.253 Airport Express (Ethernet connected)
DHCP Starting and ending Range 100 to 104.
192.168.1.100 74:XX:XX:XX:XX:90 USB Wireless TP-Link
192.168.1.101 54:XX:XX:XX:XX:6C VAIO Ethernet
192.168.1.102 78:XX:XX:XX:XX:B1 VAIO Wireless
192.168.1.103 A4:XX:XX:XX:XX:49 iPad
192.168.1.104 88:XX:XX:XX:XX:79 iPod Touch
Hard code the mac addresses for the iLive stuff too.
192.168.1.1 00:XX:XX:XX:XX:7C iLive iDR48 Mix Rack
192.168.1.2 00:XX:XX:XX:XX:86 iLive T112 Surface
192.168.1.3 00:XX:XX:XX:XX:DD iLive T112 Touch Screen
I choose not to have wireless security enabled, to prevent bottlenecks on data rate speed.
My router log never shows any other devices that connected to my network.
I do not believe polling an SSID causes interference on a network if that device does not handshake and secure a connection to begin with.
Most interference issues I experience, are in areas with many SSID’s. If I go into any venue or even outside, I use my wifi analyzer on my android phone. If it sees more then 5 different access points that have a -70 dbm or higher signal strength, I will surely encounter wireless interference. Once did a show outside a college dorm and noticed over 60 routers. I could not use wireless at all that day.
