DLink were for me one of the least reliable small unmanaged switches I tried over the years. Out of those I have had (I have about 7 in the house, they get replaced when one dies), there was DLink, Linksys, HP, Netgear and TP-Link, the TP-Links are by far the most reliable in so much as I have never had one die, and now all my switches are TP-Link as all of the others gave up the gost.
The first 8-port 10G TP-Link switch I got died within a few weeks. I think its power supply fried. It's replacement has been rock solid since for the last year and change now, fortunately!
