Maybe, but I've bought things that I think are (5-port) switches (advertised as such) for in the range of $10 in various sales or on ebay, and so far, have no reason to doubt them. I guess I'll have to really test in the near future. Ok, just did a simple test -- on a 5-port switch, with 5 devices plugged in, one powered off: * solid green lights on 4 ports (when no traffic) indicate the 4 devices that are powered up * flashing green lights on 2 ports when data being transferred I believe it is a switch -- will check the other switch in service ... Ok, same thing.
