I need some help on what wireless router or what I need to do to get a longer ranger signal. There are two of us using wi-fi at a time. My wife wants to take her computer to her shop which is about 100 feet from where the router presently is. I could move it, but really don't want to. I have a Linksys AC900. I switched from a D-Link DIR-615. This one seems much faster, but signal strength is about the same. Any help greatly appreciated. Also, don't know that much about this stuff. Thanks Lewis
