This is a very strange situation
My computer is connected to the same netgear switch as my SONOS play 1.
I have another ethernet cable connected to this switch to my main router.
Last week i noticed my laptop was dropping the network connection for a few seconds every 5-10 minutes.
I diagnosed it today as my laptop connecting to the internet via my SONOS PLay 1. To do this i disconnected the main network cable going to my router and the laptop still had an internet connection - all be it around 10% of my expected speed.
When I discconected the LAN cable of the PLAY 1 it was fine.
Anyone else experienced this?
