What's the latest and greatest to extend wifi signal? Preferably looking for something that someone already has experience with or has used with good results. Needs to be easy to do for the common folk. It's not for me, as I run Ruckus Unleashed, but for a non-techy friend. Our local internet provider has these "Pods" that you can plug in anywhere in your home to provide whole home wifi. Something like that would be great. Not sure if their provider has something like this, I am looking into it.
