How to Use a Router as an Access Point

If you have a spare router, you can use it as a wireless access point (AP) to extend WiFi coverage in your home. This is a cost-effective alternative to buying a WiFi extender.

Step-by-Step Guide

1. Connect to the spare router — plug in via Ethernet and access its admin panel.
2. Disable DHCP — turn off the DHCP server to prevent IP conflicts.
3. Set a new IP — assign a static IP in the same range as your main router (e.g., if main is 192.168.1.1, set AP to 192.168.1.2).
4. Set WiFi name and password — use the same SSID and password as your main router for seamless roaming.
5. Connect via Ethernet — run an Ethernet cable from your main router's LAN port to the spare router's LAN port (not WAN).

Tips & Best Practices

• Use the same WiFi name and password on both routers for seamless roaming
• Set different WiFi channels on each router to avoid interference
• Connect to a LAN port on the AP — not the WAN/Internet port

Pro Tip: The single most impactful WiFi improvement is router placement — center it in your home, elevated, away from walls and metal objects.

Frequently Asked Questions

What is access point mode?

Access point mode turns a router into a simple WiFi transmitter. It broadcasts WiFi but relies on your main router for routing, DHCP, and firewall.

Can I use an old router as an access point?

Yes! Most routers can be configured as access points by disabling DHCP and connecting via a LAN port.
