Tech guide: Recovering WiFi passwords and fixing connectivity

Users can recover forgotten WiFi passwords through several methods: checking the physical label on the router, accessing the router's administration panel via a web browser, or retrieving saved credentials from a device already connected to the network. On Windows 10 and 11, passwords can be found in the Control Panel under Network and Sharing Center by viewing wireless properties and selecting 'Show characters'. On macOS, the Keychain Access app allows users to view saved network passwords.

To resolve wireless connectivity issues or errors regarding access points and wireless cards, users should investigate both software and hardware possibilities. Troubleshooting steps include resetting network settings, updating computer drivers, changing WiFi channels or frequency bands, and resetting the router. If these steps fail, the issue may stem from physical damage to the network card, which might require replacement.
