It would seem that one way or another, based on the network matrix, all other units are adequately able to make wireless connections either directly to this node or to another, tertiary node.ģ. This Connect, (KITCHEN) is identified as a secondary node in the network matrix.
There is only one Sonos device (Connect) with a wired connection into a TP Link Switch which in turn is plugged into an Arris wifi phone/cable modem gateway. All Sonos units are identified as either secondary or tertiary units which to me is fine but would indicate that another, non-Sonos device is acting as root. This was one of those rare times when a bandwidth increase really WAS warranted, and after the schools WAN circuit was re-provisioned, the Internet stopped mysteriously “going down.Just continuing to try to do some diagnostics on a buddy's Sonos setup and having difficulty identifying the designated root based on its mac address. He would go from room to room during art period, handing them out and teaching kids how to do video mashups. It turns out that the art teacher had been awarded a grant for 10 shiny new iPads. I repeated the times and he said, “Oh for the love of…I know what the problem is.” I called the Principal back and gave him the start and stop times of the spikes, along with the information on 10 Apple products that were to blame. A visit to WireShark’s “OUI Lookup Tool” revealed that all 10 were from Apple, Inc.
Every time there was a spike, it was the same set of MAC addresses. Correlating the spike times from our bandwidth stats, we saw that during the same period, the “top talkers” were 10 MAC addresses which all started conversations with. I decided to see if NetFlow (a new tool for me at the time) had anything to tell me. Usage would spike for 20-30 minutes, and then drop down until the next incident. My favorite.”Ī quick look at the bandwidth metrics revealed that -yes indeed -the WAN link to the school was becoming saturated at various intervals during the day. “Lovely,” I muttered under my breath, “vague AND random. One day, I found myself holding the receiver away from my head as the principal for one of the schools I supported was shouting, “The internet just keeps going down!” I replied, “How often and when?” He said, “2-4 times a day and at random times.”
