WiFi Not Working? Fix It Now™

This wifi not working fix guide finds your specific problem
Most people restart the router, wait, try again, and give up. There are seven completely different causes of WiFi failure and the fix for each one is different. Restarting the router fixes one of them. It does nothing for the other six. This tool finds which one you are dealing with in under a minute.

Three questions. Seven fixes.
The first question asks whether any device in your home is connecting right now. That single answer splits you into two diagnostic paths. If other devices work and yours does not, the problem is your device. If nothing connects, the problem is your router or your ISP. Everything that follows is specific to your situation.

The Windows 11 fix
A May 2026 Windows 11 update changed power management settings on WiFi adapters, causing WiFi to drop and not reconnect until a restart. The fix is one setting in Device Manager. The tool also covers the network stack reset sequence, the correct way to update your WiFi driver, and when to use network reset as a last resort.

The Mac fix
A confirmed conflict between AirDrop, Handoff, and WiFi background services is causing random drops on Macs running macOS Tahoe. The tool covers the exact settings to change, the DNS flush command that fixes no-internet-after-sleep, and the macOS Tahoe 26.5 update which contains targeted WiFi stability fixes for M-series Macs.

The router and ISP fixes
The correct power cycle order is modem first, fully connected, then router. Skipping the wait is the most common reason a wifi not working power cycle does not actually fix the problem. The tool also covers DNS server changes, ISP outage checks, and factory reset as a genuine last resort.

Two files in the download
The HTML tool opens in any browser, asks three questions, and routes you to your fix with numbered steps and a Did this fix it button. The PDF is a printed reference with all seven fixes laid out. No software to install. No account required.

Still wifi not working after trying the fix?
If the tool routes you to a fix and it does not resolve the problem, the fault is likely hardware or ISP. Our Network Setup and Troubleshooting service diagnoses the exact cause remotely with no callout fee. You can also check our New Laptop Setup Checklist if you just got a new device.
