I want to replace the router/modem Comcast with a high quality for streaming

Just a balancing voice that most network professionals and engineers will tell you, as per the design of IP networks, there is no SQ benefit to "audiophile grade" network gear.

I've been through the debate and don't need to do it again so I won't debate anyone in this thread...I would just encourage anyone looking to learn from these threads to understand that network and computer professionals are vastly on the side that these audiophile products do not benefit SQ. 

There may be other reasons to upgrade components including avoiding dropouts.  There are different levels of quality in network gear for sure.  But most network and engineering professionals will tell you that sound quality isn't a benefit of upgrades. 

As above, this is just a cameo appearance to balance the discussion, no need to dive into the debate rabbit hole with me in this thread. Done enough of that in other threads and on other forums this week.

Unfortunately Comcast or CenturyLink are my only 2 options for internet service right now.  Comcast is is way better, I signed up with CenturyLink when they had a deal going on with a 2 year contract, as soon as that was over I went back to Comcast as fast as I could.  Now that I am using the Comcast/Xfinity rental modem my internet is way better with very few connection issues.  Having to use their equipment is just another way for them to make more money off you, IMHO.  I am waiting for Cspire to install a fiber optic network in my neighborhood but it doesn't look like that is going to happen any time soon, so I will just have to deal with Comcast, it's that or move and believe me I have been thinking about that lately also.

Update: I got the Netgear Nighthawk and installed it. That seemed to greatly reduce the problems I’ve had. Still sometimes when I wake up in the morning my sleeping computer takes a while to reconnect to the internet. I don’t ever recall this before.

@lalitk I was unable to hook the wire to the stereo system directly to the router because the roon core has to be on the same ’network" as the phones, computers, tablets, etc that you use to control roon. I was unable to see the roon core with it plugged directly into the router and the control devices hooked to the wireless network. I can’t figure out why. My router control solftware sees all the things attached wired and wirelessly.

I will also think about your concern about hooking the stereo system up directly to the modem. No computers or other devices worth hacking bypass the modem.

I am using an eero mesh wifi because it was highly recommended to me when I was having problems. I have a TP Link almost new that I will reinatall, perhaps this afternoon.

The speed of the Netgear modem isn’t much faster if at all. speedtest comes back 360 Mbs. the old modem was 350 or so, maybe it would be 360 too today. But what I will call latency is improved. when I run speedtest it starts immediately, with no delay. same with many other websites loading.

I’ve changed some tubes lately but I will say that right now the sound system has never sounded better.

the Netgear modem was not expensive and it is nice to have a better piece of equipment in my audio system and supporting my home network for routine things like reading this site.
