I'm not tech savvy with these tablets, or computers in general. On that note...my prime has weak WiFi signal in my backyard by my firepit and I can't relocate my router anywhere else than where it currently resides. Could I plug in a WiFi signal repeater halfway between where my router is and the backyard to help get signal out back? Are these things legit or a bogus gimmick? Something like this since I have a Netgear Wireless N router: WN3000RP Thanks!
