I once bought a router to use for my internet when I moved into my new house just to find out that it “wasn’t compatible” with Verizon’s service. I still have it (because I’m terrible about returning things). Is there any point in keeping it? Is there anything fun or interesting that I could do with it?
Custom firmware like tomato or ddwrt can be fun to just play around with and learn more about networking. I used my old router temporarily as both a wifi repeater and as a wifi receiver using custom firmware. I didn’t need it for any particular function, but it was fun to experiment with
