Question: Why do devices continually look for a network?
I've got an AirPort Extreme as my router. When I look at the network under the WiFi symbol I find that my computer is continually looking/checking for networks. Is that normal?
In fact, I can see other devices scanning for networks as well and I have had some trouble with smaller devices dropping the signal (like a Kindle).
Does this mean my network (from Comcast) is dropping the signal?
I would just like my computers/Kindles/iPads to hang on to my network and stop looking for others.
Is there some setting to make it stop scanning for networks?
