Summary: I have a fairly old version of this switch, H/W Ver D3. It took me over a year, and first replacing a ton of other hardware, to discover that THIS 'efficient' device was efficiently causing network problems. All devices connected through it would often have connections die for about 3 seconds, maybe once every minute or so. As soon as I swapped in a different (very expensive) switch of mine, everything squared away immediately.
Summary: Plug in and use,works just fine. Used this one because had problems with a wireless router that was used after my modem router combo. The blue ray could figure out the wireless setup so just got this one and it works great.
Summary: Works great the first timeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee 100
