Question about D-Link DGS-2205 5-Port Gigabit Ethernet Switch (DGS2205)
Basically, it looks like it died. I get power, but my computer
can no longer sense the switch. It keeps saying cable disconnected. Doesn't work on any of the ports tried.
is there anyway to reset the box? powering on and off doesn't help.
I've opened up the box, but nothing obvious like a fried chip was seen.
Anyone else have a similar problem and solution other than going a ahead and buying a new one?
Gigabit swich does not enough for a Gigabit network, you also need to get your computers to support it, that means Gigabit network cards, buy if you don't have and you really need to, they are quite cheap these days.
If the above is not the case than it is barely possible, but worths a check, if you are using simple CAT5 cable instead of CAT5E or CAT6 (cable type is written on the cable, see for yourself)cable for the network?
If this is true consider doing a rewireing if really nessesary for speed, but cat5 is ok for gigabit around 10 meters distance for very good speeds.
However to do a little speedtest on your own first is not a bad idea at all, try to copy some big files between 2 computers and check the speed, 100Mbit networks used to do speeds about 8-10 Mbytes/sec that should do it for most networks, gigabit networks can do more, my record in my home network was 50-60Mbytes/sec, but mostly it's around 30Mbytes/sec.
Remember, better cable can do better speed and sometimes length affects network speed if the cable is very long (above 50 meters). And prepare, that you are not really going to reach the theoretical maximum speed of 125Mbytes/sec with common PC hardware. Maybe with some RAID based system or SSD can help you out, but most people don't really need that kind of speed.

SOURCE: d-link lights are all on
I don't think it has anything to do with the voltage its an issue with the ship on a certain batch , again not all the DES-1228P have that issue only few.
I am sure if you contact D-link they will replace the switch as it is a 5 years warranty

SOURCE: there is no power coming
Sounds like the power supply to the switch may be bad, if it doesn't turn the power on.
Check the voltage of the power supply with a multimeter to see what the transformer power supply is outputing.

Are you using the original power adapter ?
Use only CAT5 UTP fast-Ethernet cables no longer than 80 meters.
Connect just 5 or 6 computers to see if the problem resolves. Sometimes the internal buffer on the switch (the store-forward buffer) gets full, so the switch resets and stop forwarding packets until it get it's buffer cleared.
I hope it will help you.
