Can I use an old router as a WiFi adapter?
Yes, using an old router as a WiFi adapter is a viable option and can be achieved by enabling specific features. Many older routers can be repurposed as WiFi extenders or adapters by configuring their firmware. To do this, access the router’s settings via its IP address, and look for options such as client mode or bridge mode. This allows the router to connect to an existing WiFi network and provide internet access via its own Ethernet ports.
However, it’s important to note that not all routers support these features, so check your router’s documentation before proceeding. If your router isn’t capable of being configured in this manner, you may consider installing custom firmware, like DD-WRT or OpenWrt, which often unlocks additional functionalities. This solution is cost-effective and makes good use of an otherwise outdated device.
