It sounds like you’re experiencing a selective connectivity issue with your WPA7517, where only certain devices are unable to connect via Wi-Fi. Here are some steps you can take to troubleshoot the problem:

Restart Devices: Begin by restarting your WPA7517, PC, and ESP device to clear any temporary glitches that might be causing the issue.
Check Wi-Fi Settings: Ensure that the Wi-Fi settings on your PC and ESP device match those required by the WPA7517. This includes the SSID, password, and encryption type.
Update Firmware: Check if there’s a firmware update available for your WPA7517. Outdated firmware can sometimes lead to connectivity issues.

Device Limit: Verify if there’s a limit on the number of devices that can connect to the WPA7517 at once. If so, disconnect some devices and try connecting your PC and ESP device again.
Interference: Consider the possibility of interference from other wireless devices. Try changing the Wi-Fi channel on the WPA7517 to see if it improves the connection.
Factory Reset: As a last resort, you can perform a factory reset on the WPA7517. Be aware that this will erase all settings, and you’ll need to set it up again as if it were new.
 

If these steps don’t resolve the issue, Please tell me I am happy to help you.
