What should be the first step in troubleshooting a slow Wi-Fi network?

Analyzing signal strength is a crucial first step in troubleshooting a slow Wi-Fi network because it helps determine whether the network's performance issues are being caused by a weak signal. A weak signal can lead to dropped connections, slow speeds, and overall poor performance. By checking the signal strength, you can identify if the issue is due to distance from the router, physical obstructions, or interference from other devices.

Additionally, understanding the signal strength can guide further steps in troubleshooting. If the signal is weak, it may prompt actions such as optimizing the router's placement, reducing interference, or considering a range extender. This initial analysis sets the foundation for a more targeted approach to resolving the issue.

Other options, while potentially valid steps in different contexts, may not address the root cause of slow speeds without first understanding the strength and quality of the connection. For instance, checking hardware compatibility may be essential if there are persistent issues, but it assumes that the signal is adequate. Resetting the router and rebooting connected devices are also useful tactics, but these should generally be considered after confirming that signal strength is adequate, as they do not directly assess the core issue of connectivity affecting speed.
