I have recently added a Boost to my Sonos system in hopes of having less issues with connectivity. I am still not happy with my signal strengths, I have a very small house and can't seem to get good (green) signal to each wireless device.
-- My Boost is centrally located, on a wooden shelf, about six feet above the floor.
-- The Zone Player 3 (Living Room 2) is about 15 feet from the boost, on a wood coffee table, about three feet off the floor, no walls between them.
-- My Zone Player 3 (Office 2) is 7 feet away, on a wooden shelf, about five feet off the floor, with two sheetrock walls between them.
-- My Zone Player 5 (V-1 Kitchen) is 8 feet away, on a sheetrock plant shelf, about nine feet off the floor, with two sheetrock walls between them.
-- My Zone Player 5 (V-1 Bedroom) is 20 feet away, on a wooden shelf, about five feet off the floor, with one sheetrock wall between them.
I'm not using the radios in the Zone Player 80s as they are both using a wired Ethernet connection but for completeness, one is 3 feet below the Boost, on a lower wooden shelf while the second is 5 feet away, on a wood shelf, about 7 feet off the floor, with two sheetrock walls between them.
I can't get a Network Matrix chart to appear for my Boost but this one from my Living Room ZP-80 shows the information fairly well.

I'd really like an easier way to verify my system status and signal strengths than using the web interface with a link like this:

Even having more information available (a key to colors and what the text means) on the grid shown under "Network Matrix" there would also be a good thing and save a a lot of searching for that information.
