One big room solutions please

the boost is same as having a speaker hooked to router. Some people have multiple units hooked and there is possibility of it being better or worse that way.

If its working like you have it I wouldn't go adding more wired units.

@Krislu - if all your speakers are working fine, let sleeping dogs lie!
But that is almost certainly because of a wired in Boost, which is needed ONLY if it is not convenient to have any other speaker wired to the router. But once Boost is wired, nothing else need be.

What is the best Ethernet cable? Do you mean cat 6 cable ? If I ran cat 6 cable to every play box , would this be the best option or overkill?

Many would say good option. Probably more than 1 wired in each room is overkill. Ie if you have 4 play:1s in the big room wiring all 4 with cat 6 probably overkill.

I guess best answer would be do you seem to have much wireless interference in your home such as with neighbors wifi. A sniffer app lokknnb at wifi around you would be good to check. If you have a lot of interference then at that point wiring all may be better for you (pretty much only happens in heavy urban areas/apartment condos)

"Some people have multiple units hooked and there is possibility of it being better or worse that way."

Really ? wow!

"If its working like you have it I wouldn't go adding more wired units"

It works perfect! No problems at all. I will leave well enough alone then.

Thanks

Kumar- THANKS! Yes, everything is perfect. I will take yours and Chris' advice and leave it alone.

I am currently using a Single Play:3 as my bridge device.

Thanks chris. So I will cat 6 wire 1x play 1 in the big room and have 3 x play 1 in the same room but wireless.
I will also buy a boost and then install one socket beside each play1.
Will that cover everything or have a missed the perfect setup?

You really know your stuff! Was just going to buy 2 play 5s and hope for the best!!!

I don't think you need to get a boost.
