I finally threw out my ISP router like the trash it was
I only need my ISP to do one thing, send me internet.

Listen up. If you're perfectly happy with your ISP's router, then I have one question for you—well, two, really—because I want to know how long you've had that router and what download speed you're paying for. Oh, and if you hate money because there's every chance your ISP has been charging a monthly rental fee for that router for years, and they're not likely to stop, or offer you an upgraded router now they've got new gear in.
