Why can't my PDA connect to a WiFi network?

If you have authentication issues when connecting to WiFi, it may be due to the following reasons:

1. The password may be incorrect. Please make sure that you entered the correct WiFi password.

2. Network configuration issues:

2.1 - Make sure your device is set to automatically obtain an IP address and DNS server using DHCP.

2.2 - Try to manually set a static IP address to ensure that the settings are correct and do not conflict with other devices.

3. Signal strength. If the WiFi signal is weak, the device may have difficulty completing the authentication. Try to move closer to the router or access point.

4. Device cache issues. The device may have cached incorrect configuration information. You can try the following steps:

4.1 - Forget the network: Select "Forget this network" in the WiFi settings and then reconnect.

4.2 - Restart the device: Restart your phone, computer, etc., and try to reconnect.

5. Router issues:

5.1 - Restart the router: Restarting can solve many network problems.

5.2 - Check the router settings: Make sure there are no settings such as MAC address filtering or device restrictions that prevent the connection.

6. Interference issues. Other nearby WiFi networks or electronic devices (such as microwave ovens) may also cause interference. Try changing the router's channel.

7. Reset network settings
