I got a Netgear CM1000 modem to replace my Spectrum supplied modem. I use Ifi low noise power supplies with both the modem and mesh router. I didn't hear much of a difference myself but since this modem performs better, ie less dropouts, fewer problems, I kept it. Plus the modem paid for itself in about a year by dropping my ISP's lease payment for use of their modem. Ethernet cables, I found make a difference. I prefer silver plated and also found the best ethernet cable should be at the streamer.
