Wireless router capable of getting through 2 or 3 cement walls and 75-100 feet?

    Any chance of a router available right now being able to get a decent signal through 3 cement walls and 75 feet away? Seems tough, but I haven't kept up with these new Wireless-N routers at all. My laptop has wireless-n, but my modem/router doesn't.

    Probably not a decent connection?

    You may want to try using the Wi-Fire by hField Technolgies.

    The Wi-Fire is a long-range WiFi device that will increase the range of a desired wireless network. It's performance is subject to your environment, but the Wi-Fire is a directional antenna, so it is very powerful. You can point it in the direction of the access point in order to optimize your signal.

    I use it in my home to get wireless on my third floor. And, when I plug it in I can see a collection of other networks on my street. I think the Wi-Fire is exactly what your looking for to access a hard-to-get network.

    I'd be pretty surprised if even that makes it through 3 cement walls. I'd say you are out of luck. You would have better luck drilling holes and running a cat5 cable

    Try asus WL520GU or linksys wr54g with tomato firmware. Then crank up the transmit power to something like 200mW. With the transmit power cranked up to just 80mW, i can get descent wifi signal from more than 300feet away.

    Why don't u give a layout diagram of your setup mentioning distances. As of now i feel any good router will do 75-80 feet in straight line even crossing 2-3 brick walls. I'm using a very normal type utstarcom wa3002g4 adsl modem router and when talking about straight line, my router gives 4 to 5 bars at appx 50 feets crossing three 9" brick walls. Adding any high gain antenna to your router will hlep you more. I use wireless G.

    There is a difference between BRICK and CEMENT walls. Cement is very dense--brick. less so

    The diagram is an idea worth investigating, but if we are talking


    router (CEMENT WALL WITH NO OPENINGS) room (CEMENT WALL WITH NO OPENINGS) room (CEMENT WALL WITH NO OPENINGS) computer, there is no chance a signal gets through that.

    I have a computer 20 feet away from the router separated by a 6-inch cement wall and the signal is iffy. I ended up drilling a hole and running a cable.

    Put three walls in there--not a chance.

    I think the signal will definitely be seen but the connection, most likely would be poor.

    Well we hooked up an old WRT54G, and through 2 walls it was connectable. 3 walls though and the connection was dropped. I guess we'll see about getting a stronger antennae as I didn't know those could be bought, and hopefully that will actually get it working decently. Thanks for all the comments and ideas though.

    i use 3com router and built in intel 5100 to receive , through 3 cement walls NUT not 75 feet away , the router is about 32 feet , and i get 3 or 2 bars signal and download with full speed , i am sure new wireless N routers will do better

    Absolutely, the Wi-Fire from hfield. I've been through several concrete and cement block walls with it. And I've been in situations where you just have to aim it and have found a stronger signal being reflected at right angles to where I thought the ap was - it was just on a clearer path past the concrete walls, then bouncing off a distant line of trees but it gave me a couple MB/s more than pointing straight at the ap, which was already allowing me to stream video. I'm just guessing but I'd say that situation was about 200 feet and it was either 3 or 4 interior cement block walls and an external concrete wall. No windows and only a steel security door on that sideof the building. I'd recommend it if you ever have situations with poor connectivity - hfield.com.

    But N is not likely to do better. N in actuality has worse distance characteristics than g. And obstructions like walls translate to distance one way or another. So, a good directional g adapter will do much better at penetrating those 3 cement walls than any N adapter.
