LAN Speed Test (Lite) is fully functional with no time limits, etc. only some of the more advanced features are disabled. LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless). First, you pick a folder to test to. Oct 29, 2018 Doing an initial LAN scan, the app shows all devices connected to the network—including printers, MacBooks, tablets and servers. I then found one device and tested the ping to that device, which fluctuated between 19ms and 39ms every second; however, after watching the pings for a while, more and more 200ms pings showed up sporadically. There are some solid command-line (Terminal) tools, such as iperf, that let you do this, as well as a number of traditional Mac apps. But Speedy Net (Mac App Store link), which I discovered last.

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.

Many of us are already using fast broadband connections these days and it’s important to know whether the information you are sending or receiving is correct and error free. When there is an error in sending or receiving data you might have problems downloading or uploading files and they could fail MD5 checksums or appear corrupt and the downloaded Zip or Rar archive won’t open etc. For example, if you keep getting errors sending packets but not receiving, then that could actually point to a faulty network adapter.

Error information can be an important first step in troubleshooting a connection. It’s very easy to view the basic network connection information, and you can see a network connection’s current status, connection duration, speed and packets or bytes sent and received for the connection. This is usually found by double-clicking the status icon in the system tray or going through Network and Sharing Center > Change adapter settings in Vista and above. The Status dialog box by default shows nearly everything but weirdly chooses not to display errors for the connection.

Before using sophisticated or tough to use packet sniffing software to detect packet loss and errors, you can just enable a hidden setting in Windows to show you any possible errors with your connection. Here’s how to do it with a quick registry change and the information will be added to the status dialog window.

If you’re not comfortable in the registry or just want to make things as quick and easy as possible, we’ve made a small registry file. Simply download and double click the file to import the ShowLanErrors value into your Windows XP, Vista or 7 registry. There’s also a .reg file should you wish to turn the error display off again.

Alternatively, please follow the instructions carefully as editing your registry incorrectly could cause problems.

1. Press Win key+R to bring up the Run box and type regedit to launch the Windows registry editor.

2. Navigate to the following registry location:


If the StatMon key is not there, right click on Connections, select New -> Key and enter the value as StatMon.

3. Inside the StatMon key, set the ShowLanErrors DWORD value as 1 if it’s already there. If ShowLanErrors is not there, right click on StatMon and select New -> DWORD value. Set the DWORD value name as ShowLanErrors. Double click on ShowLanErrors and set the value data as 1.

To turn error count off again, just set the ShowLanErrors DWORD value to 0. Microsoft claims that because most users do not need this information and might find it confusing or misleading, error counts do not appear by default. It certainly can be useful in diagnosing the network reliability though and should be enabled by default, or at least have a tick box somewhere so you can turn it on easily.

You will now see an additional Errors information in your connection status below the Sent and Received Bytes. If you still can’t see anything, restart your computer although the effect should be instant when you right click and select Status.

Unfortunately there is a drawback with the packet error display which is not every version of Windows will show the errors. It is known to display on Business, Professional or Ultimate versions of Windows XP, Vista or 7. Windows XP Home and any Vista or 7 Home editions we believe don’t work. Also, this registry edit seems to have no effect in Windows 8, we tried on Windows 8 Pro x86 without success.

When connected via VPN, the connection status window also shows the error. It appears that as long as you have a connection that goes through your network interface card (NIC), it will show the error information. In addition, the connections that can display the errors also include USB ADSL modems and WiFi adapters etc.

Very helpful, ty! Am running W7 Pro sp1, x64. Chose manual regedit solution and it worked perfectly. BTW, had to create both StatMon and ShowLanErrors. For ShowLanErrors had choice of Dword 32 bit or Qword 64 bit. Since this change was OS related selected Dword 32 bit.

FYI: no need for a reboot on WinXP here.
It showed up after adding the Regkey.


You don’t need to restart your system. After editing the registry (XP SP3) it showed the Errors right away. Just needed to close/open the status window.
