I received the Dell on Nov 19 and immediately started loading Updates after startup.  This is where the problems started.  I have a 58 Mbps Internet connection and downloads are usually very, very fast.  I took 2-3 hours to download the first file, which was a conglomeration of many fixes.  The Installation went relatively fast.  The next download was Service Pack 1 and that took 3-4 hours.I checked my Network speed at speedtest.net several times and it indicated from 1 Mbps to 10 Mbps and wouldn't even start a few times.  I had my old computer on the table next to it, so I moved the Ethernet cable from the Dell to the old computer and ran Speedtest several times, always indicating 58-59 Mbps.  This pretty much told me that the Network card on the Dell was Bad.I filed a return with Amazon and it was approved by the seller, who was  Candance Ross, thru Amazon - BUT, I was to pay the return shipping fee, which was $65.00.  I thought that was not right, since I bought a new computer, but was sold a DEFECTIVE one.  I have learned my lesson to not buy through one of the Amazon partners, because I am sure that Amazon would have paid for the shipping costs to return it.
