Home network router question

Always ask yourself question why would this help or improve?

Who is the provider ,this is horrible , why can’t you get a router,modem combo 

run it hardwired  then like myself remove the noise ,digital is not grounded from house to house , Linear tube Audio. Make a great LPS power supply 

removes all that garbage noise coming in  up to 8 amps. Most are 4 amps or less 12 v ,and the pathetic wall wart power supply just ads more noise 

then a decent Ethernet switch LHY -SW-8 has a temp controlled clock ,LPS ,

and low noise regulators   Decent quality Ethernet cables ,your best one goes to your end point , then you start getting good sounding digital with a decent streamer 

a good DDC after streamer a big plus also ,which I do all of the above ,remove all weak links in. The chain , being a dedicated Audiophile no stone goes unturned ,

land 100% makes a big difference.. p.s you can spend $4k just on a Ethernet switch like my brother has ,all depends how far you want to go l

Remember that the entire Internet consist of cheap equipment.

Any thoughts? Please remember when replying that I am an analogue guy trying to navigate the digital world with as little pain as possible.

There is no such thing called "digital".

Toslink is essentially a signal that pertains to modulations in light intensity --> It is ANALOG

Ethernet, I2S, etc are signals composed of voltage modulations ---> It is ANALOG

They are just as ANALOG as your turntable which spun around and gave you lowfi/midfi sound....What you are referring to as "digital" is just a lot more hifi ANALOG than your lowfi/midfi analog turntable. It requires some careful execution and it isn’t exactly plug n play.

Hope that helps.

A lot of wrong info here. You don’t need the modem to be out in the open, the function of the modem is to connect it to a router and that router needs to be in the open for better WiFi distribution. The best setup is to have the modem and the router separate. 
I setup corporate networks in the 90’s and people make things so complicated. You have many options on routers, buy your own or get a supplied one from your isp. The master router (could be your only router) will hook up to the modem and this router will need to be setup with your WiFi ssid, passwords, and any tweaking of channels, port forwarding, etc..

‘This is where it can get more complicated. Most homes today (except for studio apartments) you will need more than 1 router to get better coverage. Mesh is the best way to do this but only if you use the current 6e/7 standard mesh routers. This allows you to use the backhaul with a private channel that is very fast and only used between the routers. Also, the best setup is to wire all the routers using cat 6 or above cables, only use the backhaul if you can’t wire them together.

I use 4 mesh routers in my house and each router provides an Ethernet connection thru a switch to my roon endpoint. 
‘Always use wired connections, never use wap’s, Ethernet over power lines, even WiFi to an audio device, use a wired connection.
