We live in a condo, and recently purchased the Nighthawk R8500 router. The signal is great, until you get to my daughter's bedroom which is about 100 feet away. It gets even worse when you go into her closet, which is where her "office" is. Our cable guy recommened a wi-fi extender, but I'm not sure which model to get. Do I need to buy one that is compatible with the Nighthawk? I'm a stay-home Mom, not a tech person...sorry if the question seems silly. Any help would be appreciated!
