• Modem Status: Verify that your modem is working correctly and has an active internet connection. Try rebooting the modem.
• Router LEDs: Check the WAN LED on the ER-605. If it's off or blinking erratically, there might be an issue with the connection to the modem or your ISP.

• Router Reboot: Power cycle the ER-605 router by unplugging it for 10 seconds and plugging it back in.
• ISP Connection Type: Confirm that the WAN connection type configured on the router matches your ISP's requirements (e.g., Dynamic IP, Static IP, PPPoE).

7.2 Cannot Access Web Management Page

• IP Address: Ensure you are using the correct default IP address (192.168.0.1) or domain name (tplinkwifi.net).
• Cable Connection: Verify your computer is directly connected to one of the router's LAN ports.
• IP Conflict: Check if your computer has a static IP address that conflicts with the router's subnet. Set it to obtain an IP automatically.
• Firewall/Antivirus: Temporarily disable any firewall or antivirus software on your computer that might be blocking access.
• Browser Cache: Clear your browser's cache and cookies, or try a different web browser.

7.3 Slow Network Speed

• Bandwidth Management: Check if any bandwidth limits or QoS rules are configured that might be restricting speed.
• Cable Quality: Ensure you are using high-quality Ethernet cables (Cat5e or Cat6) for all connections.
• ISP Speed: Verify your internet speed with your ISP.
• Firmware: Ensure your router's firmware is up to date.

7.4 Factory Reset

If issues persist, you may need to perform a factory reset. This will revert all settings to their default values.

1. With the router powered on, locate the RESET button on the front panel.
2. Use a paperclip or a thin object to press and hold the RESET button for approximately 5-10 seconds until the System LED blinks rapidly.
