If your internet feels slow, or you want to check whether you’re actually getting the speed you’re paying for, Windows has several built-in ways to check your network speed. Here’s how to use them — no third-party tools needed.
Method 1: Check Your Network Adapter Speed
This shows the speed of your physical connection (Ethernet cable or WiFi) — useful for checking whether you’re connected at full speed or whether the link is running slower than expected.
- Press Windows key + R, type
ncpa.cpland press Enter. - Double-click your active network adapter (Ethernet or Wi-Fi).
- Look for Speed in the status window — for example, 1.0 Gbps for a gigabit Ethernet connection or 433 Mbps for a WiFi connection.
Note: this is the link speed between your PC and router, not your internet speed.
Method 2: Check Your Actual Internet Speed
The quickest way is to use a speed test website. Open a browser and go to fast.com (Netflix’s speed test — loads instantly and shows download speed clearly) or search for speed test in Google, which has one built in at the top of the results.
For a more detailed test showing ping, upload and download speeds, speedtest.net is the industry standard.
Method 3: Check Real-Time Network Usage in Task Manager
If you want to see what’s using your bandwidth right now:
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the Performance tab.
- Click Ethernet or Wi-Fi in the left panel.
- You’ll see a live graph of data being sent and received, plus current speeds in the bottom panel.
Method 4: See Which Apps Are Using Your Bandwidth
If something is eating your connection and you’re not sure what:
- Open Task Manager (Ctrl + Shift + Esc).
- Click the Processes tab.
- Click the Network column header to sort by network usage — the biggest consumers appear at the top.
Common culprits: Windows Update, OneDrive syncing, backup software, or a browser with many tabs open.
Method 5: Use the Command Line to Check Connection Stats
For more detail, open Command Prompt and run:
netstat -eThis shows cumulative bytes sent and received since the last restart. Run it twice, a minute apart, to see how much traffic is flowing.
To see which programs have active network connections:
netstat -bThis lists every application with an open network connection — useful for spotting unexpected traffic.
Why Your Speed Test Result Might Be Lower Than Expected
- WiFi distance or interference — move closer to the router or connect via Ethernet to rule this out.
- Something else on the network is downloading — check Task Manager on all devices, or log into your router to see bandwidth usage per device.
- ISP throttling or outage — check your ISP’s status page if speeds are consistently low.
- Old network adapter drivers — update via Device Manager if the speed seems unexpectedly slow on a wired connection.
