Question

Changing IP Addresses with a BOOST...

I am trying to set my SONOS specific to specific IP addresses.

The current SONOS IP addresses are 192.168.xx.100 to 192.168.xx.106 as assigned via the DHCP server.The revised SONOS IP addresses are to be 192.168.xx.200 to 192.168.xx.206.

While I am well aware as to how to assign / move a DHCP ASSIGNED IP address to a DHCP RESERVED IP address (as I have successfully done for other devices) it is not working for any of my SONOS devices.

While I was looking for solutions to this through the internet I noticed that the problem MAY BE that I have a SONOS Boost connected to 192.168.xx.100 with all other devices connected to the SONOS Boost per this article (see https://sonos.custhelp.com/app/answers/detail/a_id/3453/~/how-to-check-if-sonos-is-in-a-standard-or-boost-setup ). That is I noticed saw "WM: 0" for all devices. As I understand things this is likely the problem as the SONOS devices are getting there IP Addresses from the BOOST because they are connected to the BOOST (i.e. is this correct)?

With that, please explain how I should go about creating RESERVED IP addresses when using a SONOS Boost.

TIA!

Getting to limits of my knowledge here. But will your router not allow you to reserve 100 to 106? What happens if you try to use one of 200 to 206 for a non Sonos device?

It works. That is I have assigned other devices to RESERVED IP Addresses within that range. Appreciate the suggestion though!

Thx!

Power off the Sonos units. Restart the DHCP server (presumably the router). Power up the Sonos units.

Assuming the DHCP server has taken the new reservations these should be assigned to the Sonos units.

Ratty:

First good bumping into after all these years. You may remember me from the old / original SONOS forum.

In any event, I tried exactly what you suggested (see the 8th posting in this thread) and it failed to catch onto the new RESERVED IP Addresses.

I would appreciate any and all otehr suggestions that you have.

Thx!

I cannot think of any reason that this would make a difference, but all the Sonos devices will appear to the router as wired when in Boost mode. Just throwing that in!

I guess there is also the standard advice to make sure you are running the latest firmware on the router.

Can you please expand on this comments as I am not sure I understand what you mean. Thx!

I confirm that I am running the latest firmware...

Can you please expand on this comments as I am not sure I understand what you mean. Thx!I just wondered if some setting or feature of your router caused it to treat wired devices differently, and maybe these are the only wired devices you have. Any Sonos units connected in Boost mode will be treated as wired by your router. It seems very unlikely but I am just trying to think why Sonos units might be treated differently.

So what does this tell you...

I disconnected all the SONOS devcies...I then changes / restricted the DHCP address range...I plugged the SONOS devices in and rather than taking on their reserved IP addresses, they took on the first available IP address within the DHCP range...

What could be causing this noting this only happens to my SONOS devices...

Did restricting the dynamic DHCP pool mean that the Sonos reserved IPs now fall outside of it? If so it implies that reservations are only valid if within the pool range.

BTW, the DHCP server should detect an attempt to map a MAC to multiple IPs but it would be worth checking that there aren't any duplicate entries.

Two points:

1. When I restricted (i.e shrank) the DHCP range the SONOS Zones took the first available IP addresses (note: all other devices have either static IP address or MAC ID reserved IP addresses meaning that the SONOS Zones are the only devices that i) have reserved IP addresses and ii) are not honouring / following their resered IP addresses.

This router allows reserved IP addresses outside the DHCP range. I know this to be true because I have other devices (i.e. computers, printers, iPhones, etc.) for which I can successfully set reserved IP addresses outside of the DHCP range.


BTW, the DHCP server should detect an attempt to map a MAC to multiple IPs but it would be worth checking that there aren't any duplicate entries.

Agreed and I have checked, there are no duplicates!

Any other ideas?
