Wifi Range Extender??

Thanks guys. My house is only 1900 sq feet. The router is on the complete opposite side of the house as the attached garage. I have a wifi signal in the garage. It's just a tad week for video conferencing and whatnot. My old laptop works better out there, but the new one does not. Maybe the wifi receiver on the new laptop is weaker??? I'm hoping a wifi range extender will help.
