WiFi allows your computers and mobile devices 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 via WiFi. If someone else in your house is doing very bandwidth-intensive activities like gaming, this may crowd out your application traffic.

There may be times when you connect to one WiFi network and then switch to a different one in your vicinity. Your device checks to see which network results in stronger WiFi signal for you. If it senses that the previous WiFi network resulted in stronger WiFi signal than the current one, you see this notification pop up on your device. Notifications get generated within 15 minutes of switching to a new WiFi with weak signal strength.

Notification Text	What it means	Suggested remediation
The wireless network you are currently connected to, <WiFi-name>, has poorer connection quality than a network you were recently connected to, <WiFi-name>. This might impact application performance.	You may have connected to another WiFi network in your vicinity. That has resulted in a low WiFi signal strength which is affecting your application experience negatively.	Try reconnecting to the previous WiFi network, which had better WiFi signal strength. To do so, On Windows: Go to Start Settings Network and Internet Show available networks . Select the network you want to connect to and click Connect . On Macintosh: Go to Apple menu System Preferences Network . Click Wi-Fi in the list on the left. Click the network you want to join, then click Join . If the network is protected by a password, enter it.

Clicking on the notification opens the

UI opens. It provides details about the notification along with some suggestions to fix the stated problem.

The

link opens a time series historical chart displaying the status of the WiFi connection quality 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. Hovering your cursor over the trend line shows you WiFi Quality status and the WiFi name, so if you hover your cursor over the entire trend line you will see the WiFi name change in the pop up when there is a WiFi switchover. The red dots indicate that a notification was sent to your device at that time where the dot appears.
