Regarding ethernet switch to coax router


Hello,I've gone from DSL to coax, and it's like the new coax router can't communicate with my ethernet switches.It is primarily the connection to the a Sonos speaker and for a Nokia Streaming Box 8000 that is having problems.The router is a Technicolor CGA4233. My ethernet switch is a TP-Link TL-SG105Do some settings on the router need to be changed?Does it require something more from an ethernet switch for it to work with a coax router?Does a network switch have to support certain functions in order for it to work with a coax router?I am considering buying a new ethernet switch - e.g. as below. Will that help anything?Maybe I should also change the cable between the router and the ethernet switch to cat 7? TP-Link TL-SG1005PThanks in advance.

I have just read that Sonos can create a multicast / broadcast storm. Maybe it would be better if I connect Sonos via WiFi instead.

Do you think it would help if I changed the ethernet cable between the router and the switch to cat 7?


You’re asking about network switch connections on a Sonos community site?

The only feedback I have is that Network storms can occur if two or more Sonos devices are connected to a managed switch, if the switch is unmanaged, it should properly handle the situation. 

Sonos wouldn’t be able to know the difference between a CAT-5, CAT-6 or CAT-7 cable. It deals with data, and at a relatively slow rate at that. All Sonos Ethernet ports are 10\100, not gigabit ports. 


I don’t expect that you’ll have any trouble with those switches. You should have rebooted everything after changing routers.
