I have a fairly large home office network with 2 servers, VOIP and 8 PC's. The switch is one of 3 (the others are 10/100/1000 Netgears. <br /><br />For the last year I've had very short outages, where suddenly I would see a "Cable unplugged" error" pop up on Win XP, then it would reconnect itself in a few seconds. This progressively got worse, and finally I isolated it to the D-Link hub.<br /><br />Then it got worse, but I noticed that when I would print to a Laser printer that shared the same APC UPS, I got the "Cable Disconnected" error almost every time.<br /><br />I thought that was odd, and thought perhaps there was some feedback coming from the UPS, but still odd since the other 2 hubs were not being bothered by this.<br /><br />I replaced the UPS with a new one, and the problem still did not go away. I then moved the Laser to another outlet in another room and that problem was solved, at least the printing was not shutting down the hub for 10 seconds in a reset.<br /><br />THEN it started again.....the hub resetting with all lights flashing and then coming back up.<br /><br />But then today BOOM....all my PCs lose internet connectivity and I go tot he wiring closet and there is the hub with all 8 lights flashing on and off.<br /><br />I took all the wires out, and turned it off and back on, and nothing, same problem. I tried another power brick and same thing.<br /><br />That is when I called D-Link to see if what the blinking lights mean, but then they wanted a 35$ one time fee to talk to me.<br /><br />I said forget it....why bother, I can buy a new hub for 50$!!!<br /><br />But being curious I scoured the internet and found these postings.<br /><br />Obviously we have some systemic problems here.<br /><br />Seeing the comments I opened the hub and inspected it, and NO BULGING Caps! They look perfect. I took the board out checked both sides and no sign of any circuit failure.<br /><br />QUESTION: Is there a way to test a Cap to see if it has failed even though there is no outward sign of failure?<br /><br />COMMENT: For all you who are waiting for them to admit to a problem....good luck!<br /><br />COMMENT 2: Having been a IT Manager for over 15 years, why on earth are some of you folks using this consumer grade components for what appears to be fairly large environments? <br /><br />COMMENT 3: You have to be really careful nowdays with consumer grade electronics. Black market products in China are everywhere, and they sell you stuff that is supposed to be the real deal and it is a cheap imitation. There was a huge scandal a few years back where the Chinese were selling FAKE top grade nuts and bolts to aircraft companies in the US. The US Airlines thought they were getting a great deal....until the bolts started breaking!<br /><br />Do yourself a big favor and up the budget a bit and get corporate grade. It is not worth the lost productivity to save a few hundred bucks.<br /><br />Thanks for the info, and I hope to hear back on the CAP question. Like one other said, not really worth the time to repair given the cost of the item, but I hate throwing out into the junk heap if it can be saved.<br /><br />I just ordered a 16 port 10/100/1000 with QOS from Netgear. Hope that works better than this one.
