Wi-Fi Connection Error. Can’t Connect to One Specific Wi-Fi

Windows10. There are some usable Wi-Fi in a house, but I cannot connect to one specific Wi-Fi. When I try to connect that Wi-Fi it says “can’t connect this network” even though my phone and other devices can connect to that Wi-Fi. If I unplug the Wi-Fi
router and re-plug in after 10 to 15 second, I can connect that Wi-Fi. However, it sometimes stops suddenly while I am using that. Then I need to reconnect to that Wi-Fi but can’t do it unless unplug and re-plug in again. I tried troubleshooting but didn’t
work. I can use and connect to other Wi-Fi but I don’t know why this specific Wi-Fi can’t be connected.
