WiFi allows your computers and mobile devices such as smart phones or smart watches to connect to the internet without a wire. Your device connects to a WiFi router which in turn connects your home network to the internet. Since WiFi signals are transmitted through the air, when you are closer to your WiFi router, the signal is stronger. The further your device moves from the WiFi router, the weaker your signal strength gets. This results in a poor WiFi connection. WiFi signals have trouble with the same physical barriers that might stop a sound wave, for example, corners or concrete walls. There is also a limit to how much information can be transmitted through WiFi. If someone else in your house is doing very bandwidth-intensive activities like gaming, this may crowd out your application traffic and slow down your network.

A WiFi router connects to a WiFi network with a unique name. So, when you say that you are connected to a WiFi, you are essentially saying that you are connected to a WiFi network with a specific unique name.

By default, he WiFi signal strength threshold is set to 48%. If your WiFi signal strength drops to or below 48%, your device performance drops and you receive the following notification on your device.

Notification Text	What it means	Suggested remediation
Your WiFi quality is poor, which may impact application performance. Try moving closer to your WiFi router.	You may be too far away from your WiFi router. There may be physical barriers between you and the WiFi Router You may be congesting the WiFi network with activities such as streaming, gaming, or running applications that take up too much bandwidth.	Try moving closer to your WiFi router Avoid bandwidth-intensive activities like gaming or video streaming.

If you click on the notification, the Application Experience UI opens. It provides details about the notification along with some suggestions to fix the stated problem.

The Learn More link opens a time series historical chart displaying the status of your WiFi signal strength during the last 3 hours. A slider bar placed at the right end of the chart by default shows you the most recent status. Move your mouse sideways on the chart across various points in time, to understand the historical status of the active area. Depending on where you mouse over and click in the chart, you can view the status and recommendation that was indicated at that specific time within the 3-hour window. The red dots indicate that a notification was sent to your device at that time where the dot appears.

Even though your WiFi signal strength may be poor, your device may still be connected to the internet. The color of the dot next to Internet in the left pane is indicative of the internet connection status. A green dot indicates that your device is connected to the internet. A red dot indicates that you are disconnected from the internet.

To check for historical data indicating if/when the internet was down and a notification was sent to you in the past 3-hour window, click Learn More. If there is a red dot on the chart, it indicates that a Disconnected Internet notification was sent at the time where the red dot appears.
