• Router Placement: Position the router in a central location, away from obstructions (thick walls, metal objects) and interference sources (cordless phones, microwaves).
• Antenna Orientation: Adjust the two external antennas for optimal signal reception.
• Channel Interference: In the router's wireless settings, try changing the Wi-Fi channel to a less congested one (e.g., 1, 6, or 11).
• Firmware Update: Ensure your router's firmware is up to date.

5.3 Cannot Access Router's Web Management Page

• IP Address: Ensure your computer is set to obtain an IP address automatically (DHCP).
• Correct IP: Double-check that you are typing the correct default IP address (192.168.1.1) or domain name (tplinkmodem.net).
