Hi

I have a TP-Link Wi-Fi router that is sitting in my room unused. Most of us have some old unused Wi-Fi routers lying around.

I'm not an expert in networking, but I know that these devices can send and receive radio-signals in the gigahertz range. I was thinking, if we can find any alternate uses for these unused devices?

Can we set up a private mesh-network? Where we setup two routers in the 300 meter range and use them to send information through them?

Or can we use them as broadcasting devices for a ham-radio like setup?

Thanks in Advance!!!!
