Fix Slow Internet Speed on Windows 11
Source-checked About 10 minutes
Answer
Compare another device and a wired test, run the Network troubleshooter, stop known bandwidth-heavy apps, update the adapter, and reset networking only as a last step.
Prepare the correct account, device, files, and recovery path
Confirm the exact Windows edition, active account, device ownership, hardware model, current updates, and full error before changing apps, drivers, permissions, activation, networking, or system settings. Save important work and create an appropriate recovery route. Use Microsoft or the hardware maker's exact supported package; avoid activation scripts, generic drivers, registry cleaners, permission takeovers, and commands copied for a different symptom.
Locate the bottleneck
Run comparable tests on another device and, if possible, over Ethernet. If every device is slow, restart the modem and router and contact the ISP.
Check signal and usage
Move closer to Wi-Fi, use Task Manager or Settings > Network & internet > Data usage, and pause known downloads, cloud sync, or streaming.
Run Windows diagnostics
Open Get Help and run the Network and Internet troubleshooter. Disable an incorrectly configured proxy or VPN while testing.
Update the adapter
Install Windows updates and the current Wi-Fi or Ethernet driver from the PC manufacturer.
Reset only as a last step
Use Advanced network settings > Network reset after recording VPN, virtual switch, static IP, and custom DNS settings.
Verify the result before making broader changes
Repeat the exact task described in “Fix Slow Internet Speed on Windows 11” and confirm the intended account, device, file, app, or service now behaves as described in the Answer. Check any changed setting again after one restart or fresh session where appropriate, and preserve the original data until the result is stable. If only one app, account, network, or file remains affected, keep the next recovery step limited to that scope.
Video walkthrough
If it does not work
- If only one PC is slow, compare Ethernet, Wi-Fi, adapter, VPN, and background traffic. If every device is slow, contact the ISP instead of resetting Windows.
