D-Link DGS-1008D 8-Port Desktop Gigabit Switch
I suffered from the same problem with this switch that others here have reported [periodic resets]. I returned it to D-Link for a replacement, because they had no record of any customers having such a problem and no idea what could cause it. When the replacement device arrived, I experienced the same problem–whenever I sent something to my network printer, the switch would reset, dropping all connections. I believe I’ve isolated this as a power spike issue. Each time I experienced this problem, it’s because my laser printer is coming out of sleep mode. Note that my switch is NOT plugged into the same power strip as my printer. In fact, I have my switch plugged into a surge/UPS block. One other point worth noting that I think speaks poorly of D-Link. Though they sent me the replacement product, I was charged twenty-five dollars when I hadn’t included the original “mounting kit” in the return package. The mounting kit consists of two screws and two plastic wall anchors. TWENTY-FIVE DOLLARS! Unbelievable.
