Summary: On my third order I ultimately received a switch where all the ports worked.. I suspect this degree of QC may not be limited to Cisco: I ultimately ordered 4 of the D-Link 5 port Gigabit switches for the 2 that I needed.. Same problem: one or more of the channels was quiet..
Summary: Overall, this is a nice switch for a fair price, but BEWARE the latest firmware, 1.06.2 at the time I publish this review. I took 1 networking class in college, but I do remember that switches should operate at Layer 2 of the OSI model, meaning the datalink level. Ok, that sounds like technical babble to most of you, but let me tell you why you should care.
