Встроенный анализатор Wi-Fi-подключения Mac OSX

Step 1: Press the ‘alt’ key on your keyboard and mouse-click on the AirPort icon in the menu bar, like this:

The network you have selected will display some extra info. This is what each option means:

PHY Mode: protocol being used to connect.

BSSID: The unique identifier for your airport hardware, also known as the MAC address.

Channel: Wi-Fi signals are transmitting on certain channels. A channel might conflict with other transmitters.

Security: The kind of encryption used. WPA and WPA2 are safe options. WEP isn’t anymore.

RSSI: The ‘Received Signal Strength Indication’ shows the strength of your signal. Closer to 0 is better.

Transmit Rate: The actual speed at which data is being transmitted between your access point and your computer.

MCS Index: This is a number that corresponds to protocols used to encode the radio signal.

This is already useful. Especially the RSSI and Transmit Rate, which give you an indication of how well your network is performing. But we don’t stop here.

Step 2: At the bottom of that menu is an option called ‘Wireless Diagnostics

’. Select it to open an app with the same name, after you’ve authenticated yourself. It opens with an introduction screen which we will ignore for now. Instead, we will press the command key + 2. Or go to the ‘Window’ menu and select the ‘Utilities’ option, as shown on the right here.

A window will open with more info about your AirPort network. In the menu bar of that window are 5 options. Select the 5th one called ‘Performance’.

That is what we are looking at now:

This is the window that will really help you optimize things. Move your computer around the house to see the different parameters change. You could just focus on the ‘Quality’ indicator and wait until it says ‘Excellent’ or keep an eye on the ‘RSSI’ versus ‘Noise’ indicators. I ended up disconnecting the wireless phone system and moving it around to minimize noise and I rotated the AirPort base station 180 degrees, which turned my parents signal from ‘Good’ to ‘Excellent’.
