Slow or lagging internet could be the result of both software and hardware problems. If you have already checked that your WiFi or LAN network connection is active and strong, the problem could be an IP address conflict.

If that fails to fix the problem, the browser could be the culprit. Rebooting your modem or router can fix it.

Clearing your browser history, cookies and cache can revive your browser performance. Added extensions tend to also cause issues, so removing unnecessary ones will help. To test whether these problems persist, you can reinstall your browser or use another one entirely to see if this resolves it.
