My old router died and after researching, thought I'd buy this router...DIR655.  Made all the connections, but I could not configure the router, no matter how I tried.  Tried online help, but no go.  I called the number listed for Tech Support and couldn't understand the company name by the person who answered.
I asked if it was D-Link Tech Support and he assured me it was.  Well then the run around began:  He told me I was the 100th caller and would receive $600 worth of merchandise all for free except for a $11.95 processing fee.  I told him I was not interested, just wanted help with my router installation.  He said he would take care of that as soon as I told him why I wasn't interested in the "free" thing.  This went on for about 5 mins....I kept telling him I wasn't interested, he kept asking me why...I finally hung up.  Didn't get my problem solved and the D-Link is now on it's way back to Amazon.  And of course, I will never buy another DLink product.
