How to Check Network Adapter Connection Speed in Windows 11
Windows 11 shows your network adapter connection speed by displaying how fast your computer can send and receive data. This “Link Speed” is the maximum connection rate between your PC and your router or modem, not your actual internet speed. For instance, a standard Gigabit Ethernet connection usually shows up as 1000 Mbps.
Knowing this speed helps you troubleshoot network problems. If your Link Speed is lower than it should be, it might point to issues with your network cable, the port on your device, or your adapter’s settings.
You can check your network adapter speed in Windows 11 via Task Manager, Settings, or Control Panel. In Settings, navigate to Network & internet, click your active connection’s Properties, and look for “Link speed.” Task Manager’s Performance tab also displays speed for Ethernet or Wi-Fi.
Method 2Check via Windows Settings
This method provides a clean view of your current network status.
- Open Settings (⊞ Win+I).
- Click Network & internet on the left.
- Click Properties for your active connection.
- Scroll down to find Link speed.
Method 3Check via Network and Sharing Center
This is the classic way to view your Network Interface Controller (NIC) status.
- Open Control Panel and select Network and Sharing Center.
- Click the blue link next to Connections.
- A window will pop up showing the Speed.
Method 4Check via PowerShell
For advanced users, PowerShell provides a quick summary of all adapters.
- Right-click the Start button and select Terminal (Admin). [Requires Admin Privileges]
- Type the following command and press Enter:
Get-NetAdapter | select interfaceDescription, name, status, linkSpeed
How to Change Network Adapter Speed Settings (GUI)
If your internet connection feels slow, you can try changing your network adapter speed settings in Windows 11 through Device Manager. This guide will walk you through the steps to adjust these settings if they are affecting your network speed.
- Right-click the Start button and select Device Manager. [Requires Admin Privileges]
- Expand Network adapters.
- Right-click your adapter and select Properties.
- Go to the Advanced tab.
- Find Speed & Duplex in the list and change the value from Auto Negotiation to your desired speed (e.g., 1.0 Gbps Full Duplex).
Troubleshooting Slow Speeds
When your Windows 11 computer has slow network speeds, troubleshooting involves checking a few simple things. You should look at your cables, consider which Wi-Fi band you are using, and see if your network adapter drivers need an update to improve your network speed.
- Cables: Ensure you are using a Cat5e or Cat6 cable. Old Cat5 cables are limited to 100 Mbps.
- Wi-Fi Band: 2.4GHz Wi-Fi is slower than 5GHz. Check your router settings to ensure you are connected to the 5GHz band.
- Drivers: Outdated software can throttle performance. Learn how to update network drivers in Windows 11.
Summary
Checking your network adapter speed in Windows 11 is important to ensure your hardware is working right, and you can do this easily with tools like Task Manager, while also remembering to check cables and drivers if speeds are slow.
Why does my link speed show 100 Mbps instead of 1 Gbps?
This usually happens due to a hardware limitation. Check that your Ethernet cable is at least Cat5e or Cat6. If the cable is damaged or the port on your router only supports 100 Mbps, your computer will automatically negotiate down to the highest speed both devices can handle.
Does a higher link speed mean faster internet?
Not necessarily. Link speed is the capacity of your local connection to the router. If your internet service provider only gives you 50 Mbps, having a 1 Gbps link speed will not make your internet faster. It only ensures that your local network is not the bottleneck.
