[COLOR=#000000]SONOS network-attached speakers use 802.1d (STP) to detect and resolve mesh-network loops. Does the TL-SG1005D support 802.1d?

Hi

There is no information about STP on TP-Link TL-SG1005D Datasheet.
Most unmanaged switches don't support Spanning Tree Protocols.
You need L2 managed switches for STP features.

by the way, STP (ieee 802.1d) is pretty much unmanaged (certainly as unmanaged as, say, DHCP). it's hard to build reliable, loop-free networks without using the spanning tree protocol. (imho.) cheers.
