Windows issues where connection exists but no internet access, yet USB tethering functions properly
It’s evident your PC isn’t connecting to the DHCP server, typically located on your router. The flashing lights suggest a hardware problem rather than a cable issue. I recommend restarting your router by unplugging it for 5–10 minutes, then plugging it back in. Alternatively, try connecting the Ethernet cable to another port labeled "LAN" on your router. You should find at least one working port. If you need more details about router settings, that would require deeper technical knowledge and isn’t straightforward without specific information.
