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

@nyonalake 

I feel your pain, as a Comcast customer for the last 7-8 years I tried to go the route of buying my own cable modem to save some money on rental fees.  When I decided to buy a modem instead of renting I tried the cheap way first and got a Comcast compatible modem for around 80 bucks, that was a total fiasco with all kinds of connection problems.  Then I got the bright idea to go with a top of the line Motorola that was the fastest thing I could find, the cost was somewhere between 5 to 6 hundred bucks at the time, so certainly not just any old modem.  The problem was, from the start I had connection issues with the new modem, when I had a good connection it was blazing fast, so I just dealt with those issues for around 3 to 4 years.  I had to constantly reboot all the devices connected in my home to make everything work which was a pain but I was still saving some money so I kept rebooting everything.

I finally got fed up with all the connection problems and the constant rebooting, so I went to our local Comcast/Xfinity store and picked up their latest modem.  Since hooking the new Xfinity modem up to run my internet my connections issues are gone, and the new Xfinity modem is faster than the Motorola was.

  So, here is my opinion on running a modem while on Comcast/Xfinity service that you are not paying them to rent.....they intentionally cause the connection issues with modems that you don't rent from them just so you will finally get tired of it and do exactly what I did-rent from them.  I can't prove any of that so of course this is only my opinion, but since I am renting from them again all my connection issues have pretty much disappeared.  Hope this help, good luck if you do decide to buy your own modem.

OK.  I just pulled the trigger on a Netgear Nighthawk.  Docsis 3.1 and 2 gigabyte internet ports.  I see some modems that can handle higher speeds up to 2.5GB but in my neighborhood service seems to max at 350MB/sec.  The tech mentioned that they would have to pull fiber before they can go faster than that.  It is difficult to upgrade in my neighborhood as everything is underground. Looks much better but not easy to modify.

One thing that I did make sure my new modem has is 2 ports.  The Spectrum (Comcast) modem only has one port so my cable to my audio system has to plug into my router.  Now the audio system will plug directly into the modem.

It will be here this afternoon.  Wish me luck.

There may be other options but this thread is about modems.  

That snarky remark was inappropriate and obtuse.  I  have ventured down the road of a better and new Modem, and like others, stayed with (in my situation) a Verizon 1G modem with a linear power supply.  The Switch X acts as a SECOND MODEM creation a network in your home completely separate from you provider network.  It is this  CLEAN NETWORK which improves the sound by eliminating all your home network traffic (significant unless you have 0 devices in your home).  This approach form me has clearly improved the sound, better than adding any other switch I have tried after the heretofore discussed modems.  So anyone considering buying an expensive modem to replace their Verizon or Comcast modem should consider this.

Well my Verizon G100 modem was FREE, and my system does sound better with the Switch X.  I can easily hear it.  That makes a difference.  Enjoy the music.

Thanks for the coaching @fastfreight .  You're quite a role model. 

@lalitk , +1 on the LinkUp 22g cat 8 cable.  I had initially run Supra cat 8 (my runs are about 40 feet) and the LinkUp is better.  I got this from you a bit ago, thanks!

Reasonable cost also from Amazon.
