Frequently Asked Networking Questions
What is the best way to secure a home Wi-Fi network?
To properly protect your home network: change the default router admin password, update your Wi-Fi SSID from factory defaults, select WPA3-Personal or WPA2-AES encryption, disable WPS (Wi-Fi Protected Setup) to prevent brute-force attacks, and set up an isolated Guest Wi-Fi network for smart home IoT devices.
Should I connect my devices to the 2.4 GHz or 5 GHz Wi-Fi band?
Use the 5 GHz band for high-bandwidth activities like video streaming, gaming, and video calls near your router, as it offers significantly faster throughput and less interference. Use the 2.4 GHz band for long-range connectivity through walls and for smart home IoT devices that do not support 5 GHz.
What does 'Wi-Fi Connected, No Internet' mean?
This error indicates that your device successfully established a local wireless link with your router or access point, but the router cannot communicate upstream with your Internet Service Provider (ISP). Common fixes include power-cycling the modem and router, checking the WAN Ethernet cable, and verifying your DNS server settings.
How do I fix Double NAT on my home network?
Double NAT occurs when two routers in series are both performing Network Address Translation (such as an ISP modem-gateway connected to your own wireless router). Resolve this by placing the ISP modem into Bridge Mode or reconfiguring your personal router as a simple Access Point (AP).
