My cable modem is from Xifinity (formerly Comcast). Since my modem is about 30’ away from my dedicated room, I use a pair of Apple Extreme routers in a mesh network configuration to feed my Telegartner M12 Switch Gold. If you would like to see my network configuration, please visit my ’Digital’ system page and click on Picture # 22.
You can avoid mesh network if you place your cable modem in the same room as your audio system. This would mean, running a short LAN cable from modem to your choice of streamer.
I am going to be soon comparing another network switch in my system. It will be interesting to see how this switch compares to my existing switch.
