- Wifi Speed Test For Mac
This speed test checks the speed between your smartphone, tablet, computer, or other device and the internet. You can run the test through a cellular (mobile) network, a wired broadband connection, or your home Wi-Fi. A gateway speed test checks the speed between your AT&T Wi-Fi gateway and our network. Test your internet speed straight from your Mac's menu bar. Not sure if your internet speed will be fast enough for that video call? Youtube videos not. Download speed is most relevant for people who are consuming content on the Internet, and we want FAST.com to be a very simple and fast speed test. What about ping, latency, upload and other things? When you click the “Show more info” button, you can see your upload speed and connection latency (ping). This site uses cutting-edge WebRTC technology to check your Internet connection's packet loss, latency, and latency jitter in your browser for free. These problems can all be caused by various similar issues, which hopefully you will be able to find and fix using this easy way to test for them. An Internet speed test will show your actual connection speed in megabits per second (Mbps). The Spectrum Internet speed test will prompt your browser to attempt to download a test (or dummy) file. The speed test will keep track of how long it takes for your computer to.
To truly understand how fast your internet is, follow these steps:
Close all applications and power down all devices that use the internet
If you have lots of devices connected to your internet, then your internet speed test results could be lower than you expect.
Use a computer that is connected to your modem through an ethernet cable. If you run a speed test using your WiFi, the speed test results could be inaccurately low.
Run the speed test to see what your upload and download speed is. We recommend running the test multiple times to account for any fluctuations in speed that you may experience.
This speed test will not complete while connected to a VPN. In order to complete this speedtest you must disconnect from your VPN.

- Signal strength is measured in decibel milliwatts (dBm) and you can install an app on Windows to measure it. You can see this value on a Mac without adding any software.
- If your signal strength is lower than about 50 dBm, there are troubleshooting steps you should take to improve your connection.

When having Wi-Fi connection problems, most of us instinctively look at the bars on our computer or phone screen to see how strong our Wi-Fi connection is. That's the equivalent of checking the oil level in your car by looking for the warning light on your dashboard – it only tells you about your car's oil level in the most approximate way. There are much more precise tools available.
You can measure signal strength several different ways. Sometimes, it's indicated in terms of network speed, as in how many Mbps the network allows you to upload data. But this is only a user-friendly approximation: It's officially measured in decibel milliwatts (dBm).

How to check Wi-Fi signal strength on a Mac
If you're using a Mac, you can see the dBm level of your Wi-Fi network with a simple shortcut. Simply press and hold the option key while clicking the Wi-Fi icon in the menu bar to see the signal strength in decibels.

RSSI, or received signal strength indicator, is the key metric for your Wi-Fi's signal strength.
How to check Wi-Fi signal strength on Windows
There's no Wi-Fi signal strength meter built into Windows, but there are several apps to choose from – both paid and free – that can do this for you. We recommend inSSIDer because it is free, reliable, and easy to understand. To get started with inSSIDer, follow the direction on the installation page: install the app, create a free account, and use that account to log into the app.

How to interpret your network's signal strength
Decibels are expressed as negative numbers, and the closer to zero the number, the stronger the signal. In other words, the larger the absolute value, the weaker the network connection. For example, -80 dBm is a much weaker connection than -30 dBm.
In addition, signal strength isn't linear; it's logarithmic, which means that every 3 dBm change represents a halving or doubling of the strength of the signal. Moreover, a 10 dBm change adds up to ten times more or less strength.
Here are some guidelines for assessing your signal strength:
- -30 dBm. This is the maximum signal strength you could achieve, and it probably means you are within a couple feet of the Wi-Fi router.
- -50 dBm. Anything from -30 dBm to -50 dBm is excellent and is often about as high as you can get.
- -67 dBm. This is the lowest value that will deliver acceptable results for most online services.
- -80 dBm. This is the lowest possible value that will make a connection between the router and computer, but it's too weak to be useful for any online service.

If your Wi-Fi signal is weak, there are a lot of possible causes, and your troubleshooting options are extensive. Some of the simple fixes include:
- Make sure your Wi-Fi router is positioned in a central place in your home or office.
- Ensure the router's antennae are positioned optimally.
- Move your Wi-Fi transmission to a different, less-crowded channel.
