Purchased computer. It arrived. I set it up.  I noticed that the Device Plug/unplug sound kept happening.  Didn't know why.  Discovered that Internet connection kept dropping so I assumed it was the wireless network usb dongle.  It appears to be the case.  Installed all updates available.  Restarted computer.  Tried different USB outlet.  Still issue.  Described the aforementioned to the service department through their provided email address.  I got a response that I need to call them.  I called them during normal hours.  It went directly to voice mail.  I left them an email and they didn't respond.  I never received a call back  (I left a through and detailed message).  I called again over an hour later (still within their operation hours listed) and it went directly to voicemail.  I am simply sending the whole PC back.  I was willing to have them send me a replacement part but this computer is for a client and they need it set up.  I will just walk in to a store and buy one.  This isn't worth the hassle.  Would not recommend this product nor the seller.
