I am looking to buy a WiFi booster, and may have actually purchased a product that I thought was a wifi booster but is indeed not. Here is the link, http://www.ebay.com/itm/Netgear-Wireless-Universal-Dual-Band-4-Port-Wifi-Range-Extender-WN2500RP-/111267483411?_trksid=p2047675.l2557&ssPageName=STRK%3AMEWNX%3AIT&nma=true&si=sdsa7soWHpDkUv8Me1l9bSM24qE%253D&orig_cvip=true&rt=nc. If anyone could tell me if that is a wifi booster, and how it works that would be great. Because my exisitng internet setup contains a modem, and a router that is connected to that modem that broadcasts my wifi. I need to use a wifi booster to wirelessly connect to that router and extend the signal to my second story room.
