How to Check Wi-Fi Network Signal Strength in Windows 11
Checking Wi-Fi signal strength in Windows 11 lets you test how well your computer connects to your wireless router. Strong wireless signals give you faster and more reliable web browsing, while weak signals cause slow downloads and dropped connections.
Windows shows your signal using simple taskbar bars, but you can also check the exact signal strength measured in dBm (decibel-milliwatts). Readings at -70 dBm or lower mean you have a struggling connection that needs fixing.
Look at the Wi-Fi icon in your taskbar ’s bottom right corner for a visual bar indicator. Alternatively, press Win+A to open Quick Settings, click the arrow next to Wi-Fi , and see signal bars for available networks. For exact percentages, use the command prompt with “netsh wlan show interfaces”.
Option 1Taskbar Corner
Look at the Wi-Fi icon in the bottom right corner of your screen. The number of bars shown tells you the signal strength. More bars mean a stronger connection.

Option 2Quick Settings
- Press Win+A to open Quick Settings.
- Click the arrow next to the Wi-Fi button.
- You will see a list of networks with their current signal strength shown by bars.


Option 3Settings Menu
- Open Settings by pressing Win+I.
- Select Network & internet on the left, then click Wi-Fi on the right.
Here, the signal strength for your current connection is visible. Click Show available networks to see the strength of all nearby networks.


Option 4Task Manager
- Press Ctrl+Shift+Esc to open Task Manager .
- Click the Performance tab.
- Select Wi-Fi from the list on the left.
- The signal strength is displayed at the bottom of the window.

Option 5Network and Sharing Center
- Open the Control Panel and click Network and Sharing Center.
- Your current network name is listed next to Connections. The bars next to it indicate your signal strength.
- Click the network name to open a status window that shows signal quality.


Option 6Command Prompt
Command Prompt queries extract exact percentage metrics for wireless signals in Windows 11. This method bypasses visual guesses and provides hard numbers regarding signal quality. Launching the terminal utility and executing a specific query reveals the underlying wireless metrics.
- Right-click the Start button and select Terminal or Command Prompt.
- Type the following command and press Enter:
netsh wlan show interfaces- Alternatively, for a simpler view, use:
- powershell
(netsh wlan show interfaces) -match '^\s+Signal' -replace '^\s+Signal\s+:\s+',''
Returned percentages reflect actual connection quality. Higher numbers indicate a more stable link to the access point.

Troubleshooting Poor Signal
Moving the computer closer to the router often solves sudden connection drops. Avoiding large metal objects and enclosed cabinets also prevents signal degradation. Switching frequency bands makes a noticeable difference, as 2.4GHz penetrates walls easily while 5GHz delivers faster speeds over shorter distances.
- Move your computer closer to the router.
- Avoid placing the router behind large metal objects or inside cabinets.
- Switch between 2.4GHz and 5GHz bands. 2.4GHz travels through walls better, while 5GHz is faster but has a shorter range.
- Check for channel interference by using a Wi-Fi analyzer app.
Advanced Diagnostics
Windows 11 includes built-in diagnostic tools to uncover deeper issues behind persistent connection drops.
Summary: Monitoring wireless signal metrics provides a reliable starting point for diagnosing network drops. Taskbar indicators offer quick visual checks, whereas command-line tools supply granular dBm (decibel-milliwatts) data. Maintaining signal quality above -70 dBm ensures uninterrupted web browsing. Hardware adjustments and band switching should take priority before purchasing replacement networking hardware.
What is a good dBm signal strength for Wi-Fi?
A signal between -30 dBm and -50 dBm is considered excellent. Anything between -60 dBm and -70 dBm is good and sufficient for most tasks. If your signal drops below -80 dBm, you will likely experience significant lag, buffering, and frequent disconnections from your wireless network.
Why does my Wi-Fi signal strength fluctuate in 🪟 Windows 11?
Fluctuations happen due to physical obstacles like walls, distance from the router, or electronic interference from other devices. Channel congestion, where neighbors use the same Wi-Fi channel, also causes drops. Moving your router to an open, central location often stabilizes these signal variations significantly.
How do I improve my Wi-Fi signal strength without buying new hardware?
You can improve signal by updating your network adapter drivers in Device Manager. Also, change your router's wireless channel to one that is less crowded. Ensure your router firmware is updated and keep the device in an elevated, central position away from other electronics to minimize interference.
