Comcast upgraded my internet speed, should I get a DOSCIS 3.1 modem?

[Charlie22911]

I've got a surfboard sb8200 > pfSense > gigabit managed switch.

Downloads and streaming have never been an issue for me, but uploads are abysmal on all Comcast tiers that are available to me; 250Mbps down and 10Mbps up is so lopsided.

One DOCSIS 3.1 modem that is also "Cox Voice compatible":

Results for three different test sites on Cox 15/2 service:

When you talk streaming using gigabit or high speed connections. You really need a wireless AC connection. Even in a best case scenario I cannot see sustained downloads higher than 400mbps via wireless AC. At minimum a 5Ghz wireless connection. I stream via wireless AC for my 4K tv. Never a glitch or stutter.

I have everything wired personally. Even when the TV's NIC is 10/100 Ethernet and supports 802.11ac I find the picture ramps up to 4k more quickly when connected via Ethernet instead of wireless. Streaming never gets close to 100Mbps.

People often compare bit rate to blu-ray encoding and stream rate. With streaming today it is adjustable and software based that is not set in a standard like DVD or blu-ray. I have heard of streams for 4K in the 15mbps-25mbps range on the high end. I will say the sound on blu-ray is superior to any of the sound I have heard on streaming services.

The audio and video is very much better on UHD Blu-Ray. I stream HDR for shows and movies not available on disc and as you said, about 25 or 30Mbps is the highest streaming speed you will likely see.
