If you've followed the steps to connect your Mac to a Wi-Fi network, but the connection to your network or the Internet isn't reliable, the steps in this article might help.

Check for Wi-Fi recommendations

When your Mac tries to connect to a Wi-Fi network, it checks for issues that affect its ability to create a fast, stable, and secure connection. If an issue is detected, the Wi-Fi status menu in the menu bar shows a new item: Wi-Fi Recommendations. Choose it to see recommended solutions.

Wi-Fi recommendations are available in macOS Sierra or later.

Analyze your wireless environment

Your Mac can use Wireless Diagnostics to perform additional analysis.

  1. Quit any apps that are open, and connect to your Wi-Fi network, if possible.
  2. Press and hold Option (Alt) ⌥ key, then choose Open Wireless Diagnostics from the Wi-Fi status menu .
  3. Enter your administrator name and password when prompted.

Wireless Diagnostics begins analyzing your wireless environment:

If the issue is intermittent, you can choose to monitor your Wi-Fi connection:

When you're ready to see recommendations, continue to the summary. Wireless Diagnostics asks for optional information about your base station or other router, so that it can include that in the report it saves to your Mac.

Click the info button next to each item in the summary to see details about that item. Wi-Fi best practices are tips that apply to most Wi-Fi networks.


Back up or make note of your network or router settings before changing them based on these recommendations—in case you need to use those settings again.

Monitor your Wi-Fi connection

Your Mac can monitor your Wi-Fi connection for intermittent issues, such as dropped connections. Follow the steps to analyze your wireless environment, but choose ”Monitor my Wi-Fi connection” when prompted.

During monitoring, a window shows that monitoring is in progress. Monitoring continues as long as this window is open and you're on the same Wi-Fi network, even when your Mac is asleep.

If Wireless Diagnostics finds an issue, it stops monitoring and shows a brief description of the issue. You can then resume monitoring or continue to the summary for details and recommendations.

Create a diagnostics report

Wireless Diagnostics automatically saves a diagnostics report before it displays its summary. You can create the same report at any time: press and hold the Option key, then choose Create Diagnostics Report from the Wi-Fi status menu . It can take your Mac several minutes to create the report.

  • macOS Sierra and later saves the report to the /var/tmp folder of your startup drive, then opens that folder for you.
    To open the folder manually, choose Go > Go to Folder from the Finder menu bar, then enter /var/tmp.
  • OS X El Capitan or earlier saves the report to your desktop.

The report is a compressed file with a name that begins “WirelessDiagnostics.” It contains many files that describe your wireless environment in detail. A network specialist can examine them for further analysis.

Use other diagnostics utilities

Wireless Diagnostics includes additional utilities for network specialists. Open them from the Window menu in the Wireless Diagnostics menu bar:

  • Info gathers key details about your current network connections.
  • Logs enables background logging for Wi-Fi and other system components. The result is saved to a .log file in the diagnostics report location on your Mac. Logging continues even when you quit the app or restart your Mac, so remember to disable logging when you're done.
  • Scan finds Wi-Fi routers in your environment and gathers key details about them.
  • Performance uses live graphs to show the performance of your Wi-Fi connection:
    • Rate shows the transmit rate over time in megabits per second.
    • Quality shows the signal-to-noise ratio over time. When the quality is too low, your device disconnects from the Wi-Fi router. Factors that affect quality include the distance between your device and the router, and objects such as walls that impede the signal from your router. Learn more.
    • Signal shows both signal (RSSI) and noise measurements over time. You want RSSI to be high and noise to be low, so the bigger the gap between RSSI and noise, the better.
  • Sniffer captures traffic on your Wi-Fi connection, which can be useful when diagnosing a reproducible issue. Select a channel and width, then click Start to begin capturing traffic on that channel. When you click Stop, a .wcap file is saved to the diagnostics report location on your Mac.

Additional recommendations for best Wi-Fi performance:

  • Keep your router up to date. For AirPort Time Capsule, AirPort Extreme, or AirPort Express Base Station, check for the latest firmware using AirPort Utility. For non-Apple routers, check the manufacturer's website.
  • Set up your router using Apple's recommended settings, and make sure that all Wi–Fi routers on the same network use similar settings. If you're using a dual-band Wi-Fi router, make sure that both bands use the same network name.
  • Learn about potential sources of Wi-Fi and Bluetooth interference.

  • RSSI: The received signal strength indicator value, in units of decibels referenced to 1.0 milliwatts (dBm), as detected by the wireless LAN interface driver for the AP or peer station.
  • Signal Quality: A number between 0 and 100 that represents the quality of the signal.
  • Frequency: The channel center frequency of the band on which the 802.11 Beacon or Probe Response frame was received. The value of this column is in units of Gigahertz (GHz).
  • Channel: Channel number used by this wireless network.
  • Information Size:The total size (in bytes) of all Wi-Fi information elements received from this wireless network.
  • Elements Count: The total number of Wi-Fi information elements received from this wireless network.
  • Company: The company that manufactured the router, according to the 3 first bytes of the MAC address.
  • Router Model: The model of the router. This value is displayed only for routers that provide this information inside the Wi-Fi information elements.
  • Router Name: The name of the router. This value is displayed only for routers that provide this information inside the Wi-Fi information elements.

Summary Modes

When you switch to one of the summary modes, instead of showing the list of all networks, WifiInfoView only shows the number of networks and the average/minimum/maximum of the signal quality for every group.

For example, in the above screenshot, you can see that there are 25 wireless networks that use channel 6, 10wireless networks that use channel 11, and so on....

In the example below, you can see the there are 9 wireless routers of NETGEAR, 8 wireless routers of Sagemcom, and so on... (Be aware that some companies may appear more than once, with a little different name)

The following summary modes are available under the Options menu:Channels Summary Mode, Companies Summary Mode, PHY Types Summary Mode, and Max Speed Summary Mode

The 'Company' Column

WifiInfoView allows you to view the company name of each wireless device.The company name is determined according to the MAC address.

By default, WifiInfoView uses an internal database of MAC addresses/companies which is updated from time to time. If you want to use the most updated database, you can download it from the following link, and put in the same folderof WifiInfoView.exe:
Be aware that you must save it as 'oui.txt'

Connect Selected Access Point

The 'Connect Selected Access Point' option (F2) allows you to connect to the desired access point from the main window of WifiInfoView.This feature is especially useful if you have multiple access points with the same name, because WifiInfoView allows you choose the access point to connect., as opposed to the default wifi manager of Windows, which makes the connection according to the network name.

Command-Line Options

{Profile Name} - The name of the profile that contain the network key to connect the network. If the profile is not specified, WifiInfoView will try to find the right profile automatically.
{Network Adapter} - This parameter is needed only if you have multiple wireless network adapters. You can specify the GUID of the network adapter orpart of the network adapter name. For example, if the network adapter name is 'Edimax AC600 Wireless LAN USB Adapter', you can specify the name as 'Edimax AC600'.

Here's some examples:
