About two weeks ago a Play 5 I had in a stereo pair setup with another Play 5 started to occasionally disconnect or just freeze so I had to pull the power plug. This behavior has now started to get worse and worse to a point where it happens every 3 to 5 minutes now where before it was only perhaps once a day. It is usually a self reboot of the device, then the second time it fully freezes. Ethernet ports stop blinking the device stops doing anything.
So things I tried:
=============
I disabled wireless and tried Ethernet only, then the other way around
Switched places with the other Play 5
Changed the Line-in source from one device to the other and vice versa
Changed ethernet cables
Switched from direct router port to powerline adapter where the other play 5 was connected
Tried DHCP and fixed IP on the router
Release the stereo pair and used the Play 5 standalone
Tried just grouping with the other Play 5
Put it into another room to another ethernet port
Full factory reset and putting it back into the system
Whatever combination I try it just reboots or freezes after a few minutes while the other Play 5 works just fine.
