Wifi in refurbished PC cannot connect to network

My refurbished PC where the Wi-Fi is not connecting to any network, despite having a working internet connection on other devices. I have tried troubleshooting steps like restarting the router, resetting network settings, and updating Wi-Fi drivers, but the problem persists. The Wi-Fi icon shows that it is connected to the network, but there is no internet access, and I cannot browse or use online services. I am unsure if this is a driver issue, hardware fault, or configuration problem, and I would appreciate any guidance or solutions from the community to help me get my Wi-Fi working properly on this refurbished PC.
