While its primary role is to establish internet connectivity, modems with built-in routers can also manage the distribution of the internet connection within a network.
The Principle Behind Repurposing a Modem as a WiFi Extender
The principle behind using another modem as a WiFi extender involves exploiting the modem’s routing capabilities. By setting up the modem to connect to your main router wirelessly and then rebroadcast the signal, you can effectively create a network extension. This method is particularly useful for old or spare modems that would otherwise be discarded. It’s a cost-effective way to strengthen your WiFi network’s reach without purchasing dedicated WiFi extender devices.
Requirements and Considerations
To embark on this project, a few critical requirements and considerations must be understood:
– The modem you intend to repurpose should have wireless capabilities and support for the WiFi standard used by your main router.
– Ensure that the modem can be configured in a bridge or repeater mode, or it has the capability to be flashed with custom firmware that supports such modes.
– The location of the modem-turned-extender is crucial; it should be placed at a spot where it can receive a strong signal from your main router and relay an enhanced signal to the areas needing WiFi boosting.
– Be aware of the potential speed limitations. The rebroadcasted signal may not be as strong or fast as the original, and the throughput may be halved due to the repetition process.
