Contact TP-Link support as last resort. | | No internet after update | Settings reset to defaults | Reconfigure your ISP connection type (PPPoE username/password, dynamic IP, or static IP). Call your ISP if unsure. | | Can’t log in after update | Password reset to default | Use default credentials ( admin / admin or look on router sticker). Or press the physical Reset button for 10 seconds. |
