When your WiFi keeps asking for a password repeatedly, the issue usually stems from corrupted network profiles, incorrect settings, or router configuration problems. This behavior occurs across Windows, macOS, and Linux devices, though the solutions vary slightly by operating system. The most effective fixes involve forgetting the network and reconnecting, adjusting router settings, or updating network drivers. For Windows users, enabling automatic connection and checking the WLAN AutoConfig service often resolves the problem, while macOS and Linux users may need to reset network settings or power cycle their routers.

Key findings from the sources:

• Forgetting the WiFi network and reconnecting fixes the issue in 70% of reported cases ^[1]
• Router settings (channel width, security mode) can cause compatibility issues with older devices ^[2]
• Updating network drivers resolves software-based connection problems ^[6]
• Resetting network settings works for macOS but may not solve all cases ^[4]

Troubleshooting WiFi Password Prompts

Windows-Specific Solutions

Windows devices frequently experience this issue due to corrupted network profiles or misconfigured services. The most reliable solutions involve system-level adjustments rather than router changes. Start with the simplest fixes before attempting more complex troubleshooting.

For Windows 10/11 users, the WLAN AutoConfig service plays a critical role in maintaining WiFi connections. When this service malfunctions, it causes repeated password prompts. The step-by-step process begins with forgetting the network:

• Navigate to Settings > Network & Internet > Wi-Fi > Manage known networks
• Select your network and click "Forget" ^[1]
• Reconnect by entering the password again

If the problem persists, check these specific settings:

• Ensure "Connect automatically when in range" is enabled in Network and Sharing Center ^[3]
• Set WLAN AutoConfig service to "Automatic" via Services.msc ^[1]
• Update network adapter drivers through Device Manager ^[6]

Advanced troubleshooting steps include:

• Resetting the WiFi range extender or router to factory settings ^[1]
• Checking for third-party firewall interference that might disconnect the network ^[10]
• Testing with a USB WiFi adapter to isolate hardware issues ^[6]

Router and Cross-Platform Solutions

Router configuration problems affect all devices regardless of operating system. The most common router-related fixes involve adjusting broadcast settings and security protocols. Older devices particularly struggle with modern router configurations.

Key router adjustments to try:

• Switch between 20MHz and 40MHz channel widths (or enable dual-band broadcasting) ^[2]
• Verify the security mode matches all connected devices' capabilities ^[2]
• Update router firmware to the latest version ^[4]
• Perform a full power cycle by unplugging the router for 60 seconds ^[5]

For persistent issues across multiple devices:

• Check for typos in the saved WiFi password (case sensitivity matters) ^[5]
• Use the WPS button for temporary connection if available ^[9]
• Consider a factory reset of the router as a last resort ^[9]

MacOS and Linux users should focus on:

• Resetting network settings (macOS: Settings > General > Reset > Reset Network Settings) ^[4]
• Checking for soft-blocked WiFi adapters (Linux: rfkill list) ^[5]
• Updating NetworkManager and kernel versions (Linux) ^[8]
