After playing around with several types of routers over the years, I finally found one that works the best in my opinion. The netgear N router is the most powerful that I have found to date. The other models, I'd be lucky if the signal made it across the room, much less into another room with a wall in between. When I plugged in this unit, I thought it was gonna be just like the rest. Much to my surprise all 4 of my PC's connected right away and never had a signal drop. One of them is clear on the other side of the house and it still made a great link to the router. The unit has 3 ports...
