This Dell Optiplex computer replaces another computer like it that finally bit the dust.  It works well [though the incessant ads of Windows 10 are annoying -- but that is not the computer's fault].Why this computer only gets 2 stars has little to do with the computer itself, but with the customer service -- of lack thereof, by the distributor.When we purchased the computer, it came with both an Ethernet connection and wi-fi  capability.  While the Ethernet seems to work, the wi-fi has never worked.  I sent a message to the distributor saying it was a problem, and was there anything I could do at my end to get it to work.  They asked me a question in return that made no sense, and then never communicated with me again.  I sent two other questions, but didn't get a response either time.So we have a desktop computer that at least can communicate with the internet, even if the wi-fi is either defective of not properly configured.  I don't have the knowledge to trouble-shoot it on my own to know which.
