I have a question? I did not know where I would go to have it answered. I have a Dell XPS 2012 desktop computer, OS windows 7, 64 bits (haven't upgraded yet). This computer can run on either LAN or wireless. I prefer to run it on LAN. When I turned on my computer the end of February it would not connection to the internet using LAN. I had to go wireless. When I viewed Network connection details It said Lease Obtained Saturday, March 5, 2016 12:14:PM. Lease Expires Sunday, March 06, 2016 12:14:29PM? Just want to know How I can change this so I can go back to my LAN connection?
