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?
“Not Compatible” usually just means “We’re extracting a monthly fee from you to use out provided router”. Most likely, if you were to poke around, you could turn your ISP router/modem into a dumb modem and disable the inbuilt router, then connect your (better) wifi router to that.
