A. 1. Check your modem and router: Ensure that your modem and router are functioning properly. Restart both devices by unplugging them for about 30 seconds and then plugging them back in. This can often resolve connectivity issues. 2. Position your router correctly: Make sure your router is placed in a central location in your home, away from walls and obstructions, to improve signal strength. 3. Update firmware: Access your router's settings through a web browser (usually by typing 192.168.1.1 or 192.168.0.1) and check for firmware updates. Keeping your router's firmware up to date can improve performance and reliability.

B. 4. Check for interference: Other electronic devices can interfere with your Wi-Fi signal. Try to keep your router away from microwaves, cordless phones, and other wireless devices. 5. Use a wired connection: If possible, connect your device directly to the router using an Ethernet cable. This can help determine if the issue is with the Wi-Fi signal or the internet connection itself.
