We have areas in our house that cannot get our wireless signal using the standard modem that Time Warner provides. We switched to an Airport Extreme but that didn't give us any better signal. Are there any range extenders that anyone can recommend? We've been looking at NetGear, Securifi Almond and Amped. Does anyone have experience with these products? I wouldn't mind one that plugged directly into an outlet so there aren't more wires dangling around the house, but not at the expense of performance. Thanks.
