I am going to assume here (since you left out a lot of details) that you have the device connected to a TV? If that is the case, then I would try going into "Control Panel" and then "Power Options". Next to the plan that is currently selected click "Change Plan Settings". Now click "Change Advanced Power Settings". In the new window that pops up, check all your settings to make sure nothing in there is what is interfering with your connection. I suggest checking all of them, as you never know what can cause something. Once done click "Apply" and then "OK".
OH and a side note, that would have been 12-31-2018, unless you traveled to the end of this year and if you did I want to know how you did it!.
