Category: Troubleshooting

Choose a troubleshooting guide by the symptom you can reproduce. First check whether the issue affects one device or several, Wi-Fi or Ethernet, and one service or many. Then compare results while the connection is idle and while other traffic is active. Those observations are more useful than changing several settings at once. This section covers device-specific slowdowns, unstable wireless connections, upload problems, packet loss and timing variation. Keep notes of when the problem occurs and the changes you make. The selected guides below provide starting points for narrowing the cause before replacing equipment or changing your internet plan.
