This was improvised from this mac Answer (1 of 5): do nothing. If you decide to turn wifi on for whatever reason, it will remember that choice. This is a bash script that will automatically turn your wifi off if you connect your computer to an ethernet connection and turn wifi back on when you unplug your ethernet cable/adapter.Choose 'Turn Wi-Fi off.' When Wi-Fi is turned off, the menu icon changes to and empty indicator ( ). This is not that same question, but is related.Click the Wi-Fi icon in the menu bar. There's been a recent question asking about disabling WiFi at boot time. If you’re referring to the IP address, you can go at it from a couple directions. MAC addresses can be spoofed that is, a machine can report a different MAC address than the hardware that is installed.
In fact, I found nothing that appeared to be definitive explaining exactly what "Looking for Networks." actually means.Are any data available that document what and how many resources are being used in "Looking for Networks."? Is there any way to stop the system from "Looking for Networks." when WiFi is on and connected to a functional AP?I don't think "Looking for Networks." is a "channel scan" as discussed here and here, but I'm not certain.First off, you are correct that Looking for Networks is not a channel scan. I was unable to find anything for MacOs specifically. Yet, according the GUI, the system is "Looking for Networks." every 2-3 seconds in a mostly pointless expenditure of resources.I've searched for data to corroborate my feelings that this is a waste of resources. I certainly don't want to switch from my chosen network when I'm home. The exception being when you take a laptop into a new place. Manage multiple networks and profiles and measure your campaign."Looking for Networks." strikes me as wasted effort much of the time. Adobe cs6 illustrator cheap for macHow WiFi scanning worksIt's important to note that your Mac (or any other computer/OS) isn't doing anything actively to look for your SSID. Once you close the GUI, it no longer scans. MacOS will automatically start looking for networks when you click on the WiFi icon in the menu bar because, it's assuming (technically, the developers assumed) that you'd want to see all the available networks. When you enable " Auto Channel Selection" (default on most routers) it will automatically look for the least congested channel - that's what the discussion is referring to when talking about a channel scan.As for Looking for Networks you're right that it would be a pointless expenditure of resources, however, this is only activated when you open the GUI. This is being broadcast no matter what and has nothing to do with the client operating system (in this case macOS, but it could be Windows, BSD, or Linux) as it's being transmitted by the WAP ( wireless access point).When you scan for wireless networks, you tell the WiFi chip ( Broadcom BCM43xx for example) to listen for these frames. One of those frames is a Beacon frame and within it, there is key information about the WiFi network, but most importantly, the SSID. Beacon FrameEvery AP (by default) sends out management frames that, for a lack of a better descriptor, help manage the functions of a WiFi network. It's actually the opposite. In other words, it's a guy watching football as his significant other is trying to have a conversation. When the GUI isn't open it's passively listening. It's just that when you open the GUI it's actively listening.
