How to Turn use Cellular whenever Wi-Fi is Poor On or Off in Windows 11

You can turn on or off the feature that automatically uses your cellular connection when Wi-Fi is poor in Windows 11.

This setting ensures you maintain an internet connection even if your primary Wi-Fi is unstable or too slow for comfortable browsing.

Windows 11 Pro and Home editions can manage this. They’ll switch connections seamlessly when your Wi-Fi signal gets weak or slow. Imagine your Wi-Fi suddenly becomes sluggish during an important video call. Instead of dropping out, your PC automatically switches to your cellular data, keeping you online.

This guide shows you exactly where to find and configure this smart connection setting in Windows 11’s Settings app.

Step 1Go to Your Cellular Settings

You can find your cellular settings in Windows 11 by opening ⚙️ the Settings app and looking for the cellular options.

• Click the Start button. It’s in the bottom-left corner of your screen. This opens up everything in Windows.
• Type “Settings” in 🔍 the search bar. Click on ⚙️ the Settings app when it shows up. You can also use the Windows key + I keyboard shortcut to ⚙️ open Settings right away.
• In ⚙️ the Settings window, look for Network & internet on the left side. Click it.
• Now, find and click on Cellular. This section has all the options for your computer’s cellular data connection.

Tip: If you don’t see a Cellular option here, your computer might not have built-in cellular hardware. In that case, you would need to use an external cellular modem (sometimes called a mobile broadband device). Make sure it’s connected correctly and that Windows recognizes it.

Step 2Turn on “Use cellular whenever 📶 Wi-Fi is poor”

To make Windows 11 switch to cellular data when your 📶 Wi-Fi is bad, you need to turn on the ‘Use cellular whenever Wi-Fi is poor’ setting.

• On the Cellular settings page, you should see a switch that says Use cellular whenever 📶 Wi-Fi is poor. Make sure this switch is turned On.

If the switch is grayed out or you can’t click it, there might be a reason. Sometimes, other settings can affect this. For example, if you have turned off cellular data completely, this option might not be available. Also, make sure Windows sees your cellular modem or SIM card correctly.

Warning: When Windows uses your cellular connection, it uses data from your mobile plan. Be aware of your data limits and any possible extra costs, especially if your plan has a data cap. This feature helps you stay connected, but it’s important to know how it affects your data usage.

Step 3Understand What “Poor 📶 Wi-Fi” Means

Windows 11 decides your 📶 Wi-Fi is ‘poor’ not just based on signal strength, but also on how reliable and fast your internet connection is overall.

• High latency: This is the delay when data travels between your computer and the internet. High latency makes things feel slow, especially for things like video calls or online games that need a quick response.
• Low bandwidth: This is how fast data can be sent or received. If your 📶 Wi-Fi can’t download or upload data quickly enough, it’s considered poor.
• Packet loss: Sometimes, data packages get lost while traveling. If too many packages are lost, your connection becomes unreliable, and apps might not work right.
• Intermittent connectivity: If your 📶 Wi-Fi signal keeps dropping and reconnecting, Windows might decide it’s better to use a stable cellular connection.

By turning on “Use cellular whenever 📶 Wi-Fi is poor,” you are telling Windows to make a smart choice for you. It will choose a connection that works over a Wi-Fi experience that might be frustrating.

Summary

Turning on ‘Use cellular whenever 📶 Wi-Fi is poor’ in Windows 11 means your PC will automatically use your cellular data if your Wi-Fi connection gets slow or unreliable, so you stay connected.

What happens when done? Windows 11 monitors your 📶 Wi-Fi connection. If it detects that the Wi-Fi is performing poorly (slow, unreliable, or dropping), it will automatically switch to your cellular data connection. This makes sure you have a stable internet connection for whatever you need to do.
