Network connectivity issues on my Windows PC

Because other devices can use the same network, the fault is probably on this Windows PC or in its assigned path. Start by forgetting and reconnecting to Wi-Fi, or reseating Ethernet, then restart the PC and router. Generate the Windows wireless network report and check the latest failed session, driver version, disconnect reason, and signal quality. Compare the PC’s default gateway, DNS servers, and assigned address with a working device; an address beginning with 169.254 indicates DHCP failure. Temporarily disconnect VPN software and test after disabling third-party network filtering, without turning off Windows Firewall permanently. Install the network-adapter driver supplied by the PC manufacturer. Then run the network troubleshooter and reset the adapter. Use Network reset only after recording VPN and virtual-switch settings, because it removes and reinstalls adapters. If failure remains, test another network to separate PC configuration from router policy.
