Anyone thinking of purchasing a switch for use in an environment where there is the possibility of bridging a network intentionally or not (ie a mixed wired and wireless network where there is the possibility of creating multiple routes between network devices) should consider a switch that supports stp (spanning tree protocol) to prevent network storms from crashing the network. Sonos and Apple Airport Express are two such devices where, in certain configurations, I have witnessed storms due to a wired and wireless route being available between devices.

Switches that support STP are not standard specification so if the switch specs doesn't specifically say it supports stp then it is likely that it does not. STP is likely to be supported on managed or smart switches rather than unmanaged soho type switches.

I am currently evaluating a Netgear gs108t (not to be confused with the gs108 that does not support stp) and have found it to be nearly as plug and play as soho type unmanaged switches as long as it is used in a DHCP environment or it's subnet does not change frequently. I have yet to test it in a scenario where multiple routes may occur ie 2 Sonos players being physically connected to the same network which would simultaneously create a wired and wireless connection between the two zone players.
