What Is a Channel Overlap and Which WiFi Channel Analyzer Apps Can Detect It?

WiFi Scanner is a free 802.11 wireless scanner and connection manager for Mac OS X 10.6 Snow Leopard or later. This will detect access points and clients in ad-hoc mode if the SSID is being. A WiFi scanner app like KisMac allows you to find all kind of WiFi networks around you including hidden, cloaked, and closed ones. Sleep pillow app mac. Check the name of WiFi network, MAC address, WiFi encryption, channel, and signal level. KisMAC can also connect with GPS technology to accurately log the precise location of access points. We will be concentrating on the software side of WiFi scanners for the Mac and will point out some specific applications later in this article. We will be using a MacBook Air and the NetSpot WiFi scanning app to illustrate the features and uses of a Mac WiFi scanner. Most quality WiFI scanners will report essentially the same information. Changing your WiFi channel can be the difference between a stable connection for your devices, and a connection that makes you want to pull your hair out. Mac OS X Yosemite already has a WiFi scanner to help you find the best WiFi channel, but like in OS X Mavericks, Apple have made it sort of tricky to find.

Mac OS X has a native WiFi analyzer tool that has many new features. A great new addition is the free built-in Wi-Fi scanner tool, that also has wifi stumbler to find and discover nearby Wi-Fi networks. You can look at the screenshot below for an example of the free Mac WiFi analyzer. Go to 123.hp.com to get the latest version of the app for macOS 10.12 or later. If you are using macOS 10.11 or earlier, set up your printer using AirPrint. For more information, go to Printing with Apple AirPrint (Mac).

Wireless networks operate on five distinct frequency ranges: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz. Each frequency range is divided into several channels to minimize interference and network congestion. In this regard, WiFi channels are like road lanes. Just like multilane roadways can carry greater volumes of traffic than two-lane roads, so do WiFi channels allow more users to enjoy maximum download and upload speeds at the same time.

In most countries, the 2.4 GHz frequency range, which is the most commonly used short-distance frequency range, is divided into 13 channels with 5 MHz of channel separation. In North America, the 2.4 GHz frequency range is divided only into 11 channels, but the WiFi channel width is the same as in the rest of the world.

Because each channel on the 2.4 GHz spectrum is 20 MHz wide and the channel separation is only 5 MHz, only three channels don’t overlap with any other channels: 1, 6, and 11. This is important because WiFi channel overlap is a common cause of interference and performance degradation.

Most WiFi channel analyzer and SSID scanner apps can detect which channel a WiFi network operates on and plot all nearby networks on a graph to make it obvious which channels are used the least. Some WiFi channel analyzer and WiFi channel scanner apps, however, are far more reliable than others, and some also come with unique features that make WiFi network optimization much easier.

You can do that right on your Mac, looking at what your Mac is seeing, not what the Router is seeing.

Hold down the option key and click on the Wi-Fi icon on the menubar. you get a display like this older one:

you also immediately see names of other networks visible from your Mac, and their strength in bars.

Wireless diagnostics opens up a whole other world. There are five displays avaialable, including one that looks like most 'driver' programs:

However, DON'T create a 'diagnostics report' unless someone at Apple has asked for it. It is merely a DUMP of every possible setting that could possibly influence your correction. It is so big, it is embarrassing, so they compress it. It is useless.

In the next-to-last paragraph, they list the important functions available on the menus inside Wireless Diagnostics:

• Info

• Logs

• Scan -- finds Wi-Fi routers in your environment and gathers key details about them.

• Performance

• Sniffer

• Monitor

these are really interesting, and since you are looking for something like these, I think you will find them helpful.
