    i'm totally new to the wireless networks. i'm buying a WRT45G wireless router this week.
    and i want to make a network between me and my neighbour.
    there's a building between our buildings.
    and he lives on the 8th floor and i'm on the ground floor. i want to broadcast to him the internet from my ADSL connection.

    the distance between my window and his is about 50 meters max. but hence am in the ground floor.

    please if anyone can help me? and is it good to use antennas? can i make one? cause i can't afford buying a brand new one.

    you need WDS

    Look at the post on here for using WDS to connect two wireless routers. You will need the Alchemy firmware to do this

    thanks jagboy that was really helpful.

    probsdorg thanks to u too.
    what's a WDS tho?

    i changed my mind and i'm buying a WAG54G ADSL Modem/Router

    it's a good one, eh?
    do u have any comments about it?

    as i read about the WAG54G it can go up to 300 feet which is about 91 meters. is that true?
    and the part i don't really get is 91 meters in the free space, right? i mean with no walls or buildings in the middle right?

    wds is when you have 2 routers conected to each other wirelessly.
    here is the link to a guide
    i think that there is a wds guide here @ linksysinfo

    about how far a wap can go i am not sure. as far as i know they dont sell them in the states. sorry i cant help you there. but if you want to do wds you are going to need atleast 2 wrt54g with dd-wrt firmware or alchemy firmware

    WDS stands for "Wireless Distribution System;" in other words, repeating. The WRT is capable of this with the previously mentioned upgrades. It is said that lazyWDS is active by default on a WRT with standard firmware, but I haven't yet been able to test it. lazyWDS would allow this to happen without cofiguring it, though there are some issues with IP's, etc..., that will have to be configured.

    As far as going through another building, and from bottom floor to top, sounds pretty impossible with this kind of equipment. There are relatively inexpensive parabolic grid antennas available by the truckloads on eBay that might be an option. Another would be a chain of WDS configured WRT's, which I'm using, and other antennas, or signal boosters, etc... With home-made parabolic antennas, a WDS chain and Transmission boosting, I am struggling to provide a robust signal with much less distance and structure than your situation, though I have been successful.

    But, become a forum scavenger and you will find out what you need to know!

    thank you all for ur replies.

    now the situation has changed a bit, i've got the WAG54G, i baught it already and it's on its way to me, i should get it by Saturday.

    there's another friend of mine who lives about 2KM away from me which is about 1.24Miles.

    here's wot we had in mind as a plan. don't know if it'd work tho.

    from the article jagboy suggested to check. is it possible to get 2 antenas with 2 access points on each of our roofs and share the internet bandwidth which is about 1MBps so that the 3 of us could share the same bandwidth?

    i think you could but the bandwidth will be cut in half with the first friend you have them it will be cut in 1/3 for the third friend. i am not 100% sure.

    WDS Bandwidth

    Wait now. Doesn't that refer to total bandwidth? For instance, a theoretical (highly theoretical) bandwidth of 54Mbps would be cut in half to 27Mbps, etc... That would not effect a 1Mbps usage of a higher potential bandwidth, whatever that may be. That is my take on it, and as usual, the Good Doctor will verify with research and testing.

    Maybe someone else will chime in and set us straight if need be.
