A:Answer It's Linksys, so I'd say Yes to your first question. You place this extender somewhere midway between your router and the weak/dead area. I recommend placing close to your router only whilst you configure/set-up initially. Then unplug and place nearer your dead spot. As to how far it extends, this is difficult to say, because wi-fi network span is affected by all sorts, e.g. walls in the way, especially those with metal framing under the drywall, other network devices in between, etc.
