Ethernet Disconnects / reconnects after 2 seconds

[bookemdano]

You purchased a switch, not a hub. So you don't need to worry about any slowdown through it. Furthermore, the switch you purchased is gigabit, so you will get the max speed possible from the cMP plugged into it. If your router also has gigabit ports then it should not matter where you plug in your cMP.

But if the router only has megabit ports (100BaseTX) then you should plug the cMP into the 8-port switch you had. If you can't tell from the labels on the router itself, you could google the model number or call Comcast and ask them.

Edit: Make sure you change your cMP ethernet port back to autonegotiate the correct speed.

I have my computer directly into my cable modem and everything else plugged into a switch. You really don't want to use a hub it will slow your traffic. You want to get a switch because the traffic is routed to the IP address it's intended for and no other computer, whereas a hub sends traffic to all computers connected to the hub. I know there is a better way to explain it but it's late and right now it's the best I can do. If someone can explain it better please feel free to jump in.

So what do you have your switch plugged it to if your computer is plugged directly into the modem?

My Cable modem has 4 Gigabit ports. My computer is in one my Synology NAS is in another port and two switches in the other 2. One switch is Gigabit and plugged into that is the gigabit switch in the living room which has stuff like my AppleTV, PS3, DirecTV box. Other things in the gigabit switch connected to my modem are 2 other NAS devices, one is for Time Machine backups on all the computers on the network and the other NAS just holds junk. Pretty much all gigabit devices are in a gigabit connection. The other switch is a ethernet switch and plugged into that are all non gigabit devices like my 2 printers and some other stuff. The multiple switch route was the best way to get connections to every room in the house. My house is quite a bit older and has very very little attic space and the walls are all concrete block. So I just ran CAT6 cable through conduit up against where the soffit meets the wall on the outside of the house. So instead of 4 connections in each room I have one which limits that amount of cable I had run. It works quite well. I use Omnigraffle to map it all out and list what is plugged into what port on what switch.

Nope that makes total sense. I will use the 1 port on the router directly into the comp and use the other port for the hub to power the Sonos Boost, Apple TV and Apple Time capsule.
