I want to buy either an OEM or a generic power supply for my Dir-879 Router ASAP. I lost mine. I spent nearly a half hour on the phone with D-Link. They had absolutely no clue how to help. Can anybody here give me a part number? I'd prefer to buy a genuine D-link adapter, but it really doesn't matter at this point. Maybe you could just provide the model # of your power supply. There are lots for sale on ebay. I went to parts.us.dlink.com, but I can't find anything for the dir-879.
