your
AA wireless adapter leaves an open network for anyone to connect to? Just making sure I understand what you are saying correctly. My
AAWireless doesn't do that, and I'm pretty sure the M1 doesn't do that either. the Wireless adapters connection is fairly secure. It uses at least a basic WPA2 Protocol, as well as a companion app that goes with it that you need or the dongle doesn't do anything.
The
AAwireless adapter puts itself into sleep mode if its on for more than 5 minutes without connecting to anything, and turns back on when the car restarts.
As for interfering with wifi channels, I dont really have an answer for that as each adapter is going to operate on different channels.
