I have E31T2V1 modem. Any reason to buy an aftermarket modem?
My modem is E31T2V1 and I am using my own router, ASUS RT-AC86U and mesh with ASUS RT-AC68U. My service is Spectrum Internet Ultra which supposed to give me 400MBPS / 20MBPS. I have total of 22 devices connected (18 via Wifi and 4 via hardwired).
My questions is,
Should I get a aftermarket modem like NETGEAR Cable Modem CM1000 or ARRIS SURFboard SB8200 and replace E31T2V1 modem? Any benefit?
I am having problems recently with my download speed. It stays around 100MBPS and when I rebooted both Modem and Router, it comes back to 200MBPS ~ 220MBPS. I don't see 400MBPS any more which I used to have.
Does newer modem makes it better? What other features and benefits do those modem have?
Can I update the firmware on E21T2V1? If so, where can I find the instruction?
