Use Claude Code to hunt down home Wi-Fi slowdowns

A LinkedIn user had Claude Code test their connection, inspect signal details, and guide router tweaks that lifted speeds from about 90 to 292 Mbps.

What they did
They gave Claude Code one broad instruction to improve home Wi-Fi. The agent ran speed tests, looked at signal information from the user’s Mac, and then stepped them through changes in the router settings. The user entered the router password themselves while making the adjustments.
How it went
Claude Code identified three likely causes: a busy channel competing with a stronger nearby network, WMM being turned off, and the laptop using a slower band. After the fixes, download speed climbed from roughly 90 Mbps to 292 Mbps on a 300 Mbps plan.
Tips
Results like this depend on the router, interference, device limits, distance, and the ISP line. If you try this, make the agent explain each router change before you apply anything that could disrupt your network.

Try it yourself with Claude Code

Help me troubleshoot slow home Wi-Fi on my [router model]. My plan is [advertised speed] Mbps, and I’m using this computer at [distance from router]. First, run a speed test, check the signal details you can access, and tell me the most likely causes of the slowdown in ranked order. Then guide me through one fix at a time, pausing before any router change that could disconnect devices or affect the network so I can approve it. After each change, ask me to retest and compare the result with the original speed.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
