Summary: We've purchased 4 of these switches for our Cat 5e gigabit Ethernet house... and they have ALL failed after only 2 years! First indication is one or more ports suddenly not working. Yes, Linksys (now Cisco) fortunately provides a lifetime warranty and its a good thing since they've ALL gone bad at least once.
Summary: I purchased this unit for a remote area of our offices to replace an older 100Base-T unit. It slowed the area to a crawl. Testing showed that traffic was flowing at 1/3 the speed of the old unit. I have been trying for the last week to return the unit, but PC universe does not reply to email and calls just go to a "mailbox full" message. Fulfillment of the order was good, but customer service is NON-EXISTANT.
Summary: I bought this SD2008 switch and I had trouble from the beginning. Connected PC with gigabit eithernet, Linkstation with gigabit port, and a couple of other laptops. Could not get all to connect to my router. Very weird. I got it only to work with only 2 devices, at 100MB, so I just let it be. Finally it stopped working all together after 16 months. As for linksys/cisco support, not a good experience. I would say stay away from these "small business" linksys switches.
Summary: This product was noisy and worked for a few days but then failed. I was able to return it no problem. I've replaced it with a D-Link DGS-2208 8-Port 10/100/1000 Desktop Switch and I have to say the difference is amazing. The D-Link doesn't have a fan, so it is completely silent. How can one company make a product that requires 2 fans and another company make the same thing that doesn't require any fans?
Summary: This thing is junk. A real shame that Cisco came along and ruined a good SOHO company. Runs really really hot, I even used a fan blowing on it but it still died. It also constantly dropped and locked after about 2 mo. of service. I had 2 long runs across my house and I think it is simply not capable of handling anything but short cable runs. Maybe not even that.
Summary: The Linksys SD2008 switch (v2.2) has failed twice. The first time happened within warranty and was replaced with a remanufactured / refurbished unit. The replacement failed, this time out of warranty. The principal issue, according to the message boards, is excessive heat that damages the capacitors. Buy it at your own risk.
