This guide is about the How to Find the Best Wi-Fi Channel with Wireless Diagnostics in Mac OS X. I will try my best so that you understand this guide very well. I hope you all like this guide How to Find the Best Wi-Fi Channel with Wireless Diagnostics in Mac OS X.

Almost every semi-technical person has installed a wireless router at home or in the office, and in the process has wondered which transmission channel would be best to use. Some wi-fi routers make it simple and recommend the channel alone, but often the user has to decide on it. Let’s acknowledge the fact that most people have no idea what the best wi-fi channel would be, let alone what uses a 5 GHz wireless N network compared to a 2.4 GHz 802.11b / g network, or even what a difference between networks is. For ordinary people, it’s a bunch of irrelevant technical jargon, they just want wireless internet and want it to be fast, right? Fortunately, OS X Mavericks makes this simple when a wi-fi router doesn’t, with a simple solution provided with the included wi-fi scanner that works with every single brand of wi-fi router.

Identify the best Wi-Fi broadcast channels to use with your wireless router

To get started, you must first access the Wireless Diagnostics Utilities:

  1. Hold down OPTION and click the Wi-Fi icon in the menu bar
  2. Select “Open Wireless Diagnostics,” usually the latest option
  3. Option - Click the Wi-Fi menu to access the Wireless Diagnostics tool in Mac OS X.

  4. Enter the administrator password and skip the full splash screen
  5. Drag down the Windows menu and select Utilities
  6. Select the “Wi-Fi Search” tab and select “Scan Now”
  7. When you’re done, see the best channel recommendations in the lower right corner:
  • Top 2.4 GHz channels (usually 802.11b / g)
  • Top 5 GHz channels (usually 802.11a / n)
  • Now log in to your Wi-Fi router (this varies by manufacturer) and make channel changes as needed – this usually means using a web browser to point to the IP address of the local router (192.168.0.1, etc.)
  • This tool is included in all modern versions of OS X and is very easy to use. This is how it looks like Yosemite, note that the layout of the application is slightly different from previous releases, but the tool itself is for the most part the same and includes a scan and recommended feature for fi channels:

    In the following screenshot example, the best selected channels are 2 and 3 at 2.4 GHz and 149 and 157 at 5 GHz.

    Scan and find the best available Wi-Fi channels

    As mentioned earlier, changing the transmission channel varies depending on the router manufacturer and the IP address used. For example, using a Netgear router with an IP address of 192.168.1.1, simply point to any web browser with that IP address, log in with the router’s administrator login (often administrator / admin), and look for the channel option, usually located in “Wireless Network Settings” or the “Transmission Settings” setting area. Change the appropriate channels for each protocol, save the settings and you are done.

    Changing the Wi-Fi broadcast channel to the best option

    The Wi-Fi network should now be faster and less interfering with all the devices on the network, not just the Mac that was used to scan and detect the best channels. Furthermore, the amazing OS X Wireless Diagnostics tool can also be used to optimize Wi-Fi networks by measuring signal strength as you physically rearrange the location of your wireless router relative to your computer hardware. This works exceptionally well and you should take a little time to complete, especially if you think the wireless network is slow or problematic.

    Optimal channel recognition trick for iOS users

    Don’t have access to a Mac or Wireless Diagnostics? Maybe you don’t have OS X Mavericks yet? For users with an iPhone or mobile phone with iOS personal Wi-Fi hotspot, you can also use the roundabout to identify the best router channel. All you need to do is place your iPad or iPhone in a public area of ​​the hardware that uses your primary wireless router, and then temporarily turn on your personal hotspot. iOS scans, identifies, and selects the best possible channel, similar to the OS X scanner tool, so you can simply connect to a sent hotspot, see the channel you selected, turn off the hotspot, and reconfigure your router to use that broadcast channel. Great trick, isn’t it?
