Conflicting IP Address I Think

If there is a conflict, the first mode of order is to see if you can get them to get along. Conflict will likely not solve anything. They have to work this out.

Do any of your devices have static IP addresses on them? Any printers, other computers, etc.? It sounds like a device owns an IP that is in the DHCP range. You will need to look at your router configuration and perhaps change the range after looking at the device in question.

 

Again, you should look inside the router or the Sonos for resolving this, all devices on your network should be set to DHCP, in the router make sure there are sufficient IP addresses available, it might be set to only a short range of IP addresses.
Example, it only gives out a maximum of 10 IP addresses if it is set that way, for instance 192.168.1.2 to 192.168.1.11, if you then connect more than 10 IP addresses you might/will get conflicts.
Look if the Sonos setting is set to DHCP.

 

Sonos won't help you wrt IP Addreses. They all look to the DHCP server to provide these. if you have a Netgear router, then check the assignments there.

There is a simple way to check this. Turn everything off that gets an IP address - yes, everything.
Then turn them on in this order :

1. Router or modem and then router.
2. Switches
3. WiFi access points
4. LAN connected items
5. WiFi connected items.

Wait 2 mins between each step for boot up to complete.

Before you do that, try and list the IP addresses of all connected devices.
Then check the router's assignments of IP addresses. How long is the lease time ? It should be a day, not longer. Have you any reserved IP addresses ?

After all this compare the list of IP addresses with the previous list. What's changed ?

 

and hope the router doesn't have a limit to the number of devices that can connect.

 

Have you ever seen that ?

 

nope...just wondering if it was possible, especially for a home router.

 

Don't think it is. All subnets can do up to 255 or 256 IP addresses.

 

I wasn't thinking in terms of the subnet addresses, but rather in some kind of artificial restriction set up by the ISP.
