I've done some research and checked CNET but would like to get some opinions before making my final decision. I'm not real concerned with options and features for my router, just one that will offer me the best Wi-Fi signal from a far distance. I plan on running in the 2.4 ghz mode. I currently have ATT U-Verse Fiber optic 25mbps connection. The router/modem combo that it comes with has pretty terrible range and I want to add a secondary router to it. Suggestions???
