Sonos V8.4 / Bridge Replacement

I have a large(ish) Sonos system locked down at 8.4 (because I still use CR100 controllers). The bridge has finally died so I have temporarily wired one of my ZP Amps as a bridge. Is it possible to buy a boost and use it, or will it need me to upgrade the system version (which obviously I cannot do).

I don’t want to accidentally trash the CRs by adding a component that needs a higher software version.

There’s no way you could add a Boost. It would ship with a much more recent software version (of S2). 

Are you sure the Bridge itself has died? Normally it’s the power supply which gives up. If you have access to a meter a health PSU should put out a steady 5.1V or thereabouts. There are third party compatible PSUs available.

If the Bridge is really a goner your choices are to keep another device wired instead or to switch to WiFi (‘wireless’) mode.

Hold on. If you have another wired Sonos device and resurrecting a functional Bridge triggered a storm you have an STP problem, not a Bridge problem.

Is the Bridge the sole wired Sonos device or not?

It would still be good to have an answer to this question.  A broadcast storm should do no permanent harm.

CR100s don’t know how to nag :) (or at least they have not so far).

WRT the storm, the set up has been unchanged for 6 years after I bought the switch below and set it up to sort out the storm that originally occurred when the man cave was build (see below). To go into a bit more detail, the ‘bridge’ (or now the ZP80) is located in my office and hooked up to a Netgear GS108Tv2 switch. That switch connects to another switch in the garage block (aka my man cave) over Cat 6 wiring. Its too far away from other buildings to get a WiFi/Sonos Net link.

Similarly, a separate Cat 6 cable runs from the office to a switch in the house that in turn connects to the router (again distanced is too great for WiFi).

So in effect the ‘bridge is ethernet connected to the router. In the garage I have 10 play 1s hooked up as stereo pairs, one of which is wired to the garage switch mentioned above. This is the layout that cause the storm 6 years ago when I was using an unmanaged switch in the office. Using the settings on the managed switch sorted out the issue and all has been good until 2 days ago (yes, I agree the storm should not/would not have damaged the bridge, but I think something has gone wrong with the bridge to cause the storm - theory only).

Having now swapped the bridge out and the ZP80 in with the rest of the topology unchanged, everything is now working normally (Sonos, WiFi , and the cabled network). So, although I cannot prove its the bridge, I can say that if I connect it, a storm occurs almost immediately, with it out of the picture, all is fine.
