If Windows 10 is getting slow internet, start by restarting the PC and router, then check whether the problem affects every device or just this computer. These quick checks often identify whether the cause is Wi-Fi, an app using bandwidth, or the internet connection itself; work through the steps below before changing advanced settings.
1. Check whether the problem is Windows or the connection
Compare the same website or download on another device connected to the same network. If several devices are slow, Windows is unlikely to be the only cause: the router, Wi-Fi signal, modem, or internet service may be responsible. If only the Windows 10 PC is affected, focus on its Wi-Fi connection, network adapter, background activity, and settings.
For a useful comparison, test near the router and, if possible, connect the PC with an Ethernet cable. A wired connection that works normally while Wi-Fi is slow points toward wireless signal or interference, not necessarily Windows. Internet speed tests also vary with server choice, network congestion, and the time of day, so repeat a test rather than treating one result as definitive.
2. Restart the PC and network equipment
Save your work, restart Windows, and power-cycle the router and modem if you can do so safely. Unplugging a router for about 30 seconds before reconnecting it can clear temporary faults; allow it time to reconnect before testing. If the equipment is part of a managed workplace, apartment, or shared network, check with its administrator before unplugging it.
Restarting is a low-risk first step, but it does not repair a weak signal, damaged cable, service outage, or persistent configuration problem. Avoid repeatedly resetting the router to factory settings: that can erase network settings and require setup information.
3. Improve the Wi-Fi connection
Weak or unstable Wi-Fi can feel like slow internet, especially when the PC is far from the router or separated by dense walls. Move closer and test again. Keep the router in an open, central location where practical, and avoid placing it inside a cabinet or directly beside sources of interference. If Ethernet is available, use it as a diagnostic test as well as a possible workaround.
- On the taskbar, select the network icon and confirm that Windows is connected to the intended Wi-Fi network.
- If the connection is unreliable, select the network, choose Disconnect, then reconnect and enter the password if prompted.
- For a saved network that may have stale settings, open Settings > Network & Internet > Wi-Fi > Manage known networks, select the network, choose Forget, and reconnect.
Forgetting a network removes its saved connection details, so make sure you know the password first. A Wi-Fi signal indicator does not measure internet speed: a strong signal can still have a slow internet connection, and a fast service plan cannot overcome a poor wireless link.
4. Find apps using bandwidth
Downloads, cloud synchronization, video streams, and software updates can use a large share of a connection. Press Ctrl+Shift+Esc to open Task Manager, then select Processes. If the Network column is not visible, right-click a column heading and enable it. Sort by Network to see which running apps are transferring data.
Pause or close an app only if you recognize it and do not need its current activity. A download or synchronization task may be legitimate, and ending an unfamiliar process can interrupt work. Windows Update can also use bandwidth while downloading or installing updates; let an active update finish or schedule it for a more convenient time rather than disabling updates indefinitely.
5. Run Windows network troubleshooting
Windows 10 includes a network troubleshooter that can detect some common connection and adapter problems. Open Settings > Network & Internet > Status and select Network troubleshooter if that option is available. Follow the prompts, then reconnect and test again. The names or availability of options can differ slightly between Windows 10 builds.
You can also use the built-in command-line tools to check whether the PC can reach a site, but they do not measure broadband speed. Search for Command Prompt, open it, and enter ping example.com. Responses show that a connection to that host is reachable; timeouts may indicate a network problem, though some hosts block ping requests. Do not assume that a failed ping alone proves the internet is down.
6. Update the adapter or reset network settings
If other devices work and the basic checks do not help, check the network adapter driver. Right-click Start, choose Device Manager, expand Network adapters, right-click the relevant Wi-Fi or Ethernet adapter, and select Update driver. You can also check Windows Update for available driver updates. If a problem began immediately after a driver change, the adapter’s Properties > Driver tab may offer Roll Back Driver.
Use a full network reset only after simpler checks. In Settings > Network & Internet > Status, select Network reset if shown, then follow the instructions and restart. This removes and reinstalls network adapters and can require reconnecting to Wi-Fi or setting up network software again. Record any needed network details first, and avoid changing proxy or DNS settings at random; incorrect values can make browsing fail.
Common causes and when to get help
“Slow internet” can describe several different problems: slow downloads, high delay in games or calls, pages that take time to begin loading, or a connection that drops. A speed test may help distinguish them, but the result depends on the test server and current network conditions. If possible, compare wired and wireless results, test more than one device, and note when the issue occurs.
Contact your internet provider if multiple devices remain slow on both Wi-Fi and Ethernet, or if service repeatedly disconnects. Ask a network administrator for help on a managed connection. If only one PC remains slow after a restart, checking its adapter, installed software, and updates is more relevant than buying a faster router or changing the service plan.
Frequently Asked Questions
Why is the internet slow only on my Windows 10 PC?
Possible causes include a weak Wi-Fi link, an app downloading in the background, an adapter driver issue, or a saved network configuration problem. Compare the PC with another device and test Ethernet if available to narrow it down.
Will restarting my router make Windows 10 internet faster?
It can clear a temporary router or modem fault, but it will not fix every cause. If only the PC is slow while other devices work normally, investigate Windows and its connection too.
Does a strong Wi-Fi signal mean my internet should be fast?
No. Signal strength describes the wireless link between the PC and router, not the speed of the internet service or congestion beyond the router.
Should I reset Windows 10 network settings?
Try it only after restarting, checking Wi-Fi, and investigating background use. A network reset can remove saved connection settings and require you to reconnect.
Why does my speed test change each time?
Results can vary with Wi-Fi conditions, other users and apps sharing the connection, server selection, and internet congestion. Run repeat tests under similar conditions and compare devices rather than relying on one reading.
