Hello. Whenever I leave my computer awhile and it enters sleep mode it knocks me off AOL so that when I wake the computer up I have to log back into AOL. It also disrupts the wifi because I get a message that my wifi has been restored. I can't find anything in the settings to keep it from doing this. When I access power in settings there is only the option for selecting length of time of nonuse before entering sleep mode. I've never had a computer do this before. I would appreciate any help I could get. Thanks in advance.
